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.
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:
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.For players that don't own Secrets of the Obscure, is the best option.
Food
Utility
Activate off cooldown. Due to the cooldown penalty from , try not to be too far from your mech when activating . 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:
provides barrier, and 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.
Across the four skills, Short bow offers barrier, healing, CC, , , and some . This means you can be pretty effective by just using skills 2-4 off cooldown. can be held on to for CC or .
Much like with shield, you want to balance the need to maintain with holding for (much like ).
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:
As Short bow has a fire field and two blast finishers, it can be used to quickly stack up with an optimised opener, such as:
Combined with , this should be sufficient to reach 25 in a matter of seconds even if no-one else is contributing.
Significant healing over time can be added from the following skills:
and are the most important skills here. is nice, but it is also a water field so on some encounters it may be worth holding on to for burst healing.
has the same cooldown as , and has about half the cooldown. This means you can use the cooldown of to track the cooldown of the other skills whilst not in their respective kits - Use both skills whenever you use , and hop into an extra time when is on a ~15s cooldown.
You can just about maintain permanent protection by using and either both shield skills or (Short Bow) off cooldown. However these skills also offer significant utility, so feel free to delay them if they will be needed.
You only really have one burst skill available, the appropriately named , but you can get some more by comboing available blast finishers with the water field from or . These are:
As you may be using the first four skills in your rotation, 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 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 , all your blast finishers are heals in their own right.
While not a burst heal per-se 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 , 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 and spam and . Be aware that neither of these skills heal you, and you're no use to your team if you get downed!
already provides some measure of condition cleanse. You also have:
If you need even more, then the light fields from or (Mortar Kit) can be comboed with a blast finisher.
You don't have a huge amount of CC available, limited to:
As ideally you want to use shield skills to provide , on encounters that require a lot of CC you may wish to bring a utility skill such as or instead.
Heal Mechanist is very well suited to hand kiting and many options will work, but there are some recommendations.
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.
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.连锁反应 more valuable than the duration increase on 
生长激素.
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.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 to block Annihilate, but as you are unlikely to be in range of 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 to save yourself from Mind Crush. You won't have time to use this again in between.
