Your utility and elite skills are very flexible and you should consider all options. Note that Wells and Mantras will additionally heal via 善始善终 and 咒语回复.
You can obviously change the opener based on the encounter or your individual skill choices - just make sure you apply Quickness / Alacrity, Fury, and 25 Might as quickly as possible.
Rotation Concept
After your opener, you want to continuously summon Illusions and shatter Clones for:
Cast 强力恢复 off Cooldown to grant Regeneration via 抽象回春 and Swiftness via 菲勃古物.
Rifle Usage
Rifle is your primary weapon, which you will use most of the time.
跋山涉水2 generates a clone, grants Regeneration, and heals allies for a small amount. Cast it as often as possible.
3 grants Fury and Might and you should therefore cast it regularly. It's sequence skill, , instead heals allies for a large amount, cleanses conditions, and blinds foes - cast it whenever you need to save your allies.
5 grants Barrier and Resistance to allies. You can reactivate it to open a portal from its location, but that will increase the Cooldown.
Shield Usage
Shield is part of your secondary weapon set, which you can swap to whenever necessary.
The last part of the Scepter auto-attack chain generates a clone.
2 blocks incoming attacks and generates 2 clones. Alternatievly, you can use the recast to summon a singular clone.
4 blocks incoming attacks and summons a Phantasm that grants Protection. If you blocked an attack, you can cast its sequence skill, , which has the same properties.
5 can stun foes twice to deal high Defiance Break. It's also useful for granting additional Might and Swiftness.
Shatter Usage
F1 is important for maintaining Might. Cast it off Cooldown.
F2 maintains Protection and Vigor. Cast it off Cooldown with three Clones.
F3 should be cast with as many Clones as possible to Daze foes.
F4 makes you (nearly) invulnerable for a short duration. You can also cast it to grant Aegis and Stability, if those boons are not available via your utility skills.
While F5 is active, all skills you cast will not be on Recharge when it ends. You should use it to double-up on boons, healing, defiance break, or any other skills you would like to cast twice in quick succession.
