Overview
Mechanist is a versatile and potent healer, capable of providing permanent 
敏捷, 
激怒 and 25 
威能 in addition to a variety of defensive boons and barrier.
The mech itself provides the majority of offensive boons, which leaves the mechanist able to handle ranged mechanics and makes it very reliable provided the mech's position is controlled. Unlike the DPS alacrity builds, it also does not require 
危机区域 to maintain 敏捷, leaving it free to be used to counter mechanics with 
圣盾 and/or 
稳固.
The greatest weakness of heal mechanist is that its self-healing is even lower than usual for a heal build, which means that it is more difficult than the common alternatives if used as a tank.
Skill Bar
Weapon Variants
- Mace/Shield is the best option for players that don't own Secrets of the Obscure, and it is worth having on the second weapon set as it has a few benefits despite the lower healing:
Skill Variants
Any of the utility skills could be swapped out if needed, just be aware of what you're sacrificing in each case:
试剂枪 offers consistent condi cleanse and healing over time. This should be your lowest priority for swapping out.
屏障纹章 is an extra source of barrier, and can cover any gaps in 敏捷 or provide projectile defence. You can also benefit from the passive damage reduction if you're tanking.
位移纹章 gives you a stun-break and allows you to precisely position the mech if needed. More importantly however, it guarantees that your mech will have 敏捷, which is what affects the cooldown of your command skills.
Some ideas for extra utilities:
Thanks to the recommended relic, 
卡拉科萨古物, any blast finisher can be used as an additional heal, notably:
投掷地雷 becomes a great all-round skill, offering CC, boon rip and healing.
喷火器 gives you access to 
烈焰爆弹, which has a very low cooldown.

Trait Variants
超能盾牌 if using Shield.
试验炮台 gives you access to additional boons if you bring the relevant turret.
反馈治疗 might be useful on some encounters. Typically you shouldn't struggle for 
再生 uptime, but on encounters where boons might get stripped/missed and there are frequent condis to cleanse, it can be potent.
反作用力 can be very nice on encounters with lots of condis, particularly if those condis convert to boons you otherwise have limited generation of.
连锁反应 can be very useful if you're struggling with tanking.
Equipment
Relics
For players that don't own Secrets of the Obscure, 
僧侣古物 is the best option.
Consumables
Food
碗装薄荷配菜水果沙拉 or alternatives
美味饭团 as a cheap option - it would be optimal to swap one accessory to Harrier stats Harrier stats to make up for the lost concentration.
Utility
Usage
Activate 
屏障爆发 off cooldown. Due to the cooldown penalty from 
机械天才, try not to be too far from your mech when activating 屏障爆发. Though with boon duration as high as this build has, it's not essential.
This should keep your group healthy for the most part but for optimal play you want to make use of the following:
Mace
蓄能猛攻 provides barrier, 再生 and 
活力 on a low cooldown. You want to use it off cooldown to maintain your group, and use your kits to provide extra boons and healing.
Short bow
Across the four skills, Short bow offers barrier, healing, CC, 威能, 
保护, and some 圣盾. This means you can be pretty effective by just using skills 2-4 off cooldown. 
苟且精华 can be held on to for CC or 
奔驰疾速.
Much like with shield, you want to balance the need to maintain 保护 with holding 
液怒精华 for 圣盾 (much like 危机区域).
A very useful aspect of Short bow is that its skills have the same cooldowns as key skills within your kits, so by using these skills together, you can ensure you're using them off cooldown:
流沙精华 and 
绷带冲击 (Med kit)
影流精华 and 
超级试剂 (Elixir gun)- 液怒精华 and
灌注炸弹 (Med kit) - 苟且精华 and
试剂炮弹 (Elite mortar kit) - you can hold on to these skills rather than use them in your rotation, as on-demand CC and a water field.
As Short bow has a fire field and two blast finishers, it can be used to quickly stack up 威能 with an optimised opener, such as:
- 液怒精华 - fire field
医疗包 ⇒ 灌注炸弹 ⇒ 绷带冲击 ⇒ Weapon Swap Weapon Swap-
流沙精华
-
苟且精华
Combined with 屏障爆发, this should be sufficient to reach 25 威能 in a matter of seconds even if no-one else is contributing.
Key Skills
Significant healing over time can be added from the following skills:
- 流沙精华 and 影流精华 (Short Bow) provide barrier and healing respectively.
- 灌注炸弹 (Med Kit) - Provides a large amount of 再生 as well as some other useful boons.
- 超级试剂 (Elixir Gun) - Pulses rapid healing over six seconds on a relatively short cooldown.
- 试剂炮弹 (Mortar Kit) - A water field and more healing over time.
灌注炸弹 and 超级试剂 are the most important skills here. 试剂炮弹 is nice, but it is also a water field so on some encounters it may be worth holding on to for burst healing.
灌注炸弹 has the same cooldown as 屏障爆发, and 超级试剂 has about half the cooldown. This means you can use the cooldown of 屏障爆发 to track the cooldown of the other skills whilst not in their respective kits - Use both skills whenever you use 屏障爆发, and hop into 试剂枪 an extra time when 屏障爆发 is on a ~15s cooldown.
Protection
You can just about maintain permanent protection by using 危机区域 and either both shield skills or 液怒精华 (Short Bow) off cooldown. However these skills also offer significant utility, so feel free to delay them if they will be needed.
Burst Healing
You only really have one burst skill available, the appropriately named 
体力爆发, but you can get some more by comboing available blast finishers with the water field from 试剂炮弹 or 
净化区域. These are:
As you may be using the first four skills in your rotation, 
强酸炸弹 might be the only on-demand blast finisher you have so it can be beneficial to plan accordingly if you know there is some big damage incoming. Be aware that 强酸炸弹 launches you backwards, which can be very dangerous, but it can be cancelled by weapon swapping as soon as you see yourself move.
If using 卡拉科萨古物, all your blast finishers are heals in their own right.
While not a burst heal per-se 屏障纹章 can provide a good amount of barrier to protect against and incoming hit. This skill can also be used to fill in any gaps in 敏捷, or to block incoming projectiles for five seconds. Also bear in mind that the passive reduces all incoming damage by 10%, which may be more valuable than the active effect if you're tanking.
Finally, if a large amount of sustained healing is required you can remain in 医疗包 and spam 
医疗喷剂 and 绷带冲击. Be aware that neither of these skills heal you, and you're no use to your team if you get downed!
Condition Cleanse
超级试剂 already provides some measure of condition cleanse. You also have:
If you need even more, then the light fields from 超级试剂 or 
闪光炮弹 (Mortar Kit) can be comboed with a blast finisher.
Crowd Control
You don't have a huge amount of CC available, limited to:
原型火箭拳 (Mace)
磁力反转 (Shield) - flip skill of 
地磁护盾
投掷盾牌 (Shield) - flip skill of 
静电护盾- 苟且精华 (Short bow) - an additional daze can be triggered by using a second Short Bow skill (other than the autoattack) within four seconds.
- Given your abundance of boon duration, you can also briefly recall your mech and use
机甲坠落.
As ideally you want to use shield skills to provide 保护, on encounters that require a lot of CC you may wish to bring a utility skill such as 
小型冲锤 or 
重击炮台 instead.
Hand Kiting
Heal Mechanist is very well suited to hand kiting and many options will work, but there are some recommendations.
Skills
医疗包 only has one skill that heals you, and it's not for a huge amount so is strongly recommended it be swapped out
整流纹章 offers consistent healing while passive, and Mechanist's largest heal when activated.
H型试剂 provides a big heal, and also a good amount of protection and regeneration.
治疗炮台 has a very short cooldown and if left active pulses a huge amount of 再生.
试剂枪 is an essential skill due to 超级试剂, but 屏障纹章 is optional and 位移纹章 should be replaced
It is extremely helpful to have permanent 保护 uptime, so 重击炮台 is a good choice - make sure not to drop hands on it so that it stays alive as long as possible. Similarly, 治疗炮台 makes 再生 permanent when combined with 蓄能猛攻. As the initial overcharge also provides 再生 you are free to immediately pick it up for the cooldown reduction or detonate it for the water field combo.
Traits
The standard traits can be run, but there are options:
- 试验炮台 should be used if you're taking 重击炮台, otherwise there's no point in bringing the turret.
- You may find the damage reduction from 连锁反应 more valuable than the duration increase on
生长激素. - Alchemy or Inventions can be replaced with Explosives for
冲击护盾 and 
超然爆发. Be aware that 超然爆发 will require you to regularly hit enemies with your 
精英炮座 to trigger.
Playstyle
For a general explanation of the playstyle and some suggestions for runes and food, see the guide.
The key to this build's value is in keeping the mech on the group to provide boons, so make sure to direct it to the group whenever they are on the platform. You can save 危机区域 to block Annihilate, but as you are unlikely to be in range of 机械天才 you won't have it available for each one.
As you lack blocks, you may not be able to consistently stack five hands together, so keep an eye on your health. Use 静电护盾 to save yourself from Mind Crush. You won't have time to use this again in between.
