Stream of Light/Divine Light: Stream of Light & Divine Light is your main healing output. Divine Light applies the passive "Grace" which will buff the healing of your next stream of light or Divine Light. If the situation permits, ensure you can put grace on the target before using stream.

Seal of the Heavens: Ensure this is active at all times, in the late game do not be afraid to re-active this 30 seconds early as you may not have the spare global cool down during late sudden death damage.

Prudence: Ensure this is being used on the current kill target on cooldown, This is your primary mana regeneration.

Holy Nova: A very nice AoE heal I am finding a lot of success with in a lich heavy meta. You should aim to use this on cooldown as it also regenerates mana based on the amount of friendlies hit. With that said look to push in for triple nova's when you see the opportunity, however also be cognitive of your positioning in regards to the enemy team & what CC they may have. There is no sense pushing in for a mana regen holy nova if you will be punished for it, and end up spending more mana getting yourself out of a avoidable situation, or potentially lose the match. This ability also does a good amount of damage, and can be used during a setup where you're confident your extra damage will secure the kill. Holy Nova also applies grace, and can be followed up by a empowered Stream of Light or Divine Light.

Rite of Passage: This ability is very versatile. Defensively it can be used to create distance from enemy melee targeting you or your partners, disrupt frost mage's damage setup, or as a HoT that has very good mana value. This HoT can be used proactively right before CC to potentially prevent having to trinket/a partner use a defensive. Offensively it can be used to allow friendly melee to connect to their target, and can also be used proactively to prevent a friendly from being rooted/slowed while securing a major defensive cooldown/kill.

Purify: In Arena of Kings all CC is able to be dispelled, even physical stuns. You should be looking to use this ability to keep your teammates out of CC and in the fight. A fast reaction time is key, as purify only removes the most recent status aliment. If you find you cannot react fast enough to see value with this ability, I suggest swapping it with Heaven's Strike.

Immortality: This is your biggest defensive cooldown. Use this in situations where your partners otherwise would have died. It can also be used proactively in a situation where you know your partner would have had to use a defensive themselves or you would have had to trinket to save them, good read's can end up saving mana and saving your trinket. This spell can also be used offensively to prevent your dps from being CC'd by the enemy team, this can win game's if that CC would have lost you the kill window.

Insane damage-scholar build! Good with wiz or sin

Notes:

This build is meant to serve as a basic introduction to healing as Nihilist. Not every spell mentioned in the build will be covered in detailed writing. You can read about what each spell does by clicking on them above. 

Infuse: This is your standard healing spell, actively placed orbs will empower Infuse dependent upon which orbs are alive. 

Shadow Affinity: Another healing spell that heals more than Infuse, but has a cast time. Leaving you susceptible to interrupts. Shadow Affinity also grants your target 8% Lifesteal. This Lifesteal is highly valuable for high damage allies such as Assassin. 

Orb of Absolution: A pulsing cleanse orb which heals whenever it cleanses. 

Orb of Replenishment: A fairly straightforward pulsing heal orb. 

Orb of Wisdom:  A fairly straightforward pulsing mana/resource orb. 

Orb of Smoke: An orb which decreases damage taken, and increases outgoing damage alongside some minor lifesteal. 

Blink: Teleport to your cursors location, dealing some damage. If an enemy target needs that small bit of extra damage to be defeated, you can auto attack them and blink on them at the same time that the auto lands. Providing a burst, albeit small, amount of damage that may result in a killing blow. 

Spell Breaker: A standard 5-second shield spell. Use this on a target who has 50-70% health that you are expecting to receive incoming burst damage. Note the 20-second cooldown timer on this spell. 

Important Tips: 

Heal and Damage over-time effects can not crit. However, Orb of Replenishment can. This is because Orb of Replenishment is a pulsating healing spell, and not a heal over time. 

Positioning is important on Nihilist and it can be difficult to recover from heavy pressure. 
Do your best to avoid being the target of incoming burst or openers. 
Blinking while an enemy (Champion's charge or Elder's Bear Rush) is charging to you carries them with you to your new location. Either attempt to bait their mobility first, or use it to your advantage by baiting them back into your team. 
Orbs do not require Line of Sight, try to position them out of range of the enemy. 

Quad-Orb Healer

Introduction:
I have over 1 000 victories on Mystic, currently at 1 800 MMR. I don't claim I am the best Mystic, nor I claim this guide is perfect. Mystic is a versatile class with multiple ways to play it. It fits into any comp and is playable against any comp. Below I will go through the general build I play and its variations. I will also cover its weaknesses and strengths. In addition, I will mention a few handy tips for different situations. 

My general build: This build has defensive tools against all comps and offers ways to play aggressively. 

Healing vision: Decent bursty heal, use it when you don’t have any CDs available, and your team is under pressure. Try to avoid overusing this ability, it will make you run out of mana faster than the enemy healer, it’s not mana efficient. 
TIP: Pay attention if the target, you want to cast Healing vision on, has healing reduction applied to by an enemy. If yes, use Cleanse before to get the 100 % value out of Healing vision. Currently there are 3 classes which can apply healing reduction: Champion, Assassin, Lich.

Temporal Barrier: Your second most mana efficient spell, close behind Blessing of Sun and Moon. It provides a huge shield for 7 seconds and 15 % movement speed bonus. When the shield is depleted, you are refunded 40 % of the mana cost and close enemies are slightly slowed. Use this when you know a lot of dmg is coming towards your target. Be careful to not use it too early, good opponents will just switch targets. Do not overlook the movement speed bonus and slow, it’s useful for putting some distance between you, or the target you are using it on, and melee enemies. 

Blessing Of Sun and Moon: Your most mana efficient spell and a spell which, in my opinion, separates the best Mystics from the good ones. With 4 seconds cooldown and 8 seconds duration, you can have nearly 100 % uptime on two targets. Always have it on the ally who is being targeted. With its low mana cost you don’t have to be afraid of running out of mana due to using this spell. 

Blackout: AoE fear for 2 seconds. This ability is fantastic for setting up kills but to do so, you must run into melee range. While doing so, be sure you have some defensive spells available to immediately help yourself, such as Temporal barrier, if the aggressive attempt doesn’t work out. 

Spirit Form: 60 second cooldown. When used, it cleanses all debuffs from the target, silences them and makes the invisible. The invisibility lasts for 2,5 second unless cancelled earlier by casting spells. Allies around the target are healed every second, and when the invisibility is broken. 
TIPS: With such a long cooldown, be sure the situation truly deserves using this ability. If used on yourself, you can try to group up with your allies to provide them with the AoE healing, if necessary. Use it to counter big DoTs such as Lingering Demise. Because the initial cast silences the target, be careful not to interrupt your allies’ important spells. Timing is key. 

These abilities, in my eyes, are mandatory in every build and every way you want to play Mystic. For the last 3 spots I usually use: 

Aegis: For 7 seconds you get 30 % damage reduction and are immune to a first Hard Disable ability (Fear, Stun, Incapacitate, Polymorph, Banish). The damage reduction disappears if it prevents Hard Disable ability! Be careful what you want out if this ability. Some great examples of use: Use it on ally Wizard when they are about to cast Meteor to ensure they don’t get CCed. Use it on ally Champion to help him stick to his target. If you are playing against a team which has many DoTs, thus constant damage, and pressure, don’t be afraid to use this spell every time it’s available. 
Cleanse: The best cleanse ability in this game, removing 3 debuffs from an ally target at once and slightly healing them for every debuff cleansed. Before the match, try to think of key abilities which might be worth looking out for to cleanse. Example: Wizard’s polymorph, Champion’s and Assassin’s stuns. Quickly cleansing these effects from your ally can be crucial. If the enemy team doesn’t have abilities such as those, feel free to use Cleanse everytime it’s available to cleanse slows and DoTs. 
TIP: If you are playing against Champion, Assassin or Lich, be sure you use Cleanse before casting Healing vision to get rid of possible healing reduction applied by an enemy.

Astral Shock: One of the two offensive spells I use. Astral Shock has two basic uses: To interrupt important cast from an enemy, or to add pressure on an enemy your DPS allies are focusing due to the increased damage taken part of spell. Like with Cleanse, try to think before the match which enemy abilities are important to interrupt. For example, Wizard’s Polymorph and Meteor or a big healing ability. TIP: When your allies are hard committing to kill one target, save Astral Shock to interrupt enemy healer’s channelled heal. Those abilities usually offer a lot of hp and interrupting them increases your team’s chance to kill the target. It also deals decent amount of dmg, so if you are in a situation where you know you won’t need to interrupt any casts, feel free to use it on enemies to add pressure. 

Sometimes I exchange some of those spells for these spells: 
Dream of Prosperity: In theory a great spell against enemy comp with a constant pressure due to DoTs. Unfortunately, as of now, the spell doesn’t bounce properly making him, in my eyes, not a great choice. 

Disenchant: Sometimes I alternate between Cleanse and Disenchant, depending what comps I play against the most. Disenchant is great for cancelling Wizard’s Crystallize, and Paladin’s/Scholar’s Immortality. The spell has huge value against Elder, to remove his stacks of Mending Spirit, Elder’s most efficient source of healing, or against Lich + Nihil to remove 1 DoT from multiple allies and 1 buff from multiple. 
TIP: unless you are waiting to cancel Immortality/ Crystallize or a specific spell, try to use it as much as possible when multiple players are clumped together. 

Divination: This spell helps you win the mana battle against the enemy healer. Use it with Temporal Barrier against burst, or Healing vision, if your Barrier is not available. Use it with Blessing Of Sun and Moon against constant but low dmg. Use Divination on cooldown to gain as much mana as possible. 

General tips: 
Astral Shock and Blackout are great offensive tools, but they also require you to position aggressively, therefore enemies can attack you much easier. Experienced opponents will use this to kill you. Be very carefully with your positioning.

Focus on keeping up Blessing of Sun and Moon on at least one ally. It should be your top healing spell almost every game. 

Speaking of overall healing, don’t mind the post-game screen or enemy healer’s healing. Mystic’s power comes from preventing dmg, not healing it. 
Mystic has a lot of defensive tools but overall is very squishy. Cycle your defensive tools efficiently to not become an easy target. Use any obstacles, such as pillars, to position correctly and make it as hard as possible for the enemy to attack you. 

Majority of Mystic spells are instant casts. That leaves you with a lot of time between casts. Press that space bar and auto attack! As often as possible.

When facing DPS Paladins, they have a spell, 7 seconds cooldown, which removes the most recently applied buff from their target. Be very mindful in which order  you use defensive spells on the Paladin’s target. Preferably always have Blessing of the Sun and Moon as the most recently applied buff on the Paladin’s target, as it has the lowest cooldown. 

If playing Disenchant and you are facing Wizard who plays Chilling armor, or facing a Lich who plays Underworld Armor, casting Disenchant on them will remove these buffs. If the enemy doesn’t notice this, they will run out of mana much sooner than what would they expect. 

Stat priority
Not useful: Lifesteal, Item Rarity, Reduction of Mana burns. These stats are straight up bad for combat, avoid them. 
Decent: Critical chance, flat HP, flat mana. While not the most efficient or suited for Mystic, they are fine. 
Note: A lot of Mystic’s power comes from shields and applying damage reduction. Neither of them can crit. That’s why Critical chance is kind of bad.  
The best: Mana regen, HP regen, Damage reduction while CCed, Armor, Magic Resist
Note: mana regen is super good, get as much as you can. Stacking Damage reduction might become mandatory if you keep facing double melees, to avoid dying in CC chain. 

Main stats
1 Intelligence gives 7,92 Power 1 mana, 1 Magic Resist and 0,004 % crit chance.
1 Wisdom gives 6,69 Power, 2 mana and 0,02 mana regen per sec
Personally, I think the stats are so close in terms of value that it doesn’t matter.  For biggest Power gain (increasing your damage and heals) go Intelligence.






Popuuuh's Standard Mystic build

My general build I play and its variations. Mystic's strengths and weaknesses. 

By sacrificing your cc spells you invest for mobility and damage. Use whirling blades when it's 2+ targets, keep your bleed on 2 targets min with the help of your shadow walk. Open with a 5cp puncture then envenom for poisons since it is off gcd it is basically free. Then get 5cp and puncture someone else. Wanna finish someone off? Go with annihilate after a dissapearing act for big ambushes. If you want to discuss anything my ign: Vallenhal

High DPS Bleed Assassin

Do spread pressure instead of single target, top dps charts.
