Party roles: tank, healer and damage

Party roles in The Ember Depths 0.20: which classes take which role, what each role gives you and your allies, heals, shields, interrupts and sellsword roles.

Once you have a subclass you can take a role. It is a small bonus for you plus an aura for allies near you, never a requirement: any mix of heroes can clear a dungeon, and a balanced party does it a little safer.

Your class decides which roles you can take, and your subclass picks where you start. Casters never tank (a summoner's minions hold foes for them).

Role	What it does for you	Aura for allies
Tank	Foes find you first (×3 threat). +10% life, +5% damage reduction, −10% damage. Foes you taunt hit you 15% softer.	Guard: allies take 4% less damage
Healer	+25% healing, heals cost 15% less. 12% of your damage heals the most wounded ally, and your hits refund resource. −15% damage.	Mend: allies get +10% healing
Damage	Foes notice you less (−20% threat).	Edge: allies get +4% crit chance

Heals go to whoever needs them most. A heal that lands on an ally under a quarter of their health pops Saved!, and shields soak damage up to 30% of an ally's health.
Interrupts. A blue bar marks an enemy cast you can stop. A stopped foe is silenced; a stopped boss is Staggered and takes extra damage for a few seconds.
One buff of each kind. An ally takes only the strongest party buff in each family, so the tank's, the healer's and the damage dealer's auras all apply, but two of the same aura do not stack.
Sellswords take roles too, the ones their class allows. Set their dial on the Party sheet and they fight that way.
Finding a group. Role chips show in the lobby, the directory, chat and the group-finder, and a post can say which roles it still wants. Turn on Fill the gap and you take the first role a party is missing.
