Balance pass: every act, every class

How The Ember Depths was rebalanced in v0.13.1: death rates per act and class before and after, the level-20 fix, fairer World Tiers and the Effigy's nudge.

We play the whole campaign thousands of times with a bot that fights like an average player: it clears every pack, uses its skills, dodges most telegraphs, drinks at 40% health and equips its upgrades. Before this patch it died on Medium about once every eight attempts, and almost never at level 20. Medium is meant to sit between 15% and 35% for every class.

Medium, deaths per dungeon attempt (14 classes, 2 heroes each)

	Act I	Act II	Act III	Act IV	Act V	overall
before	10%	13%	23%	12%	3%	13%
after	19%	14%	35%	24%	18%	23%

What changed

Every dungeon's foes were re-measured and retuned so each act has real fights, with the first dungeons still gentle.
A level-20 hero gets a lot all at once (capstones, a sixth skill slot, a third attuned unique, Legend points), and Act V fell to almost no deaths. Foes from level 18 to 20 now scale up to meet it.
World Tiers past Normal already force Hard. They no longer add a steep extra climb on top, so a level-20 hero can start Veteran in campaign gear and grow into it with the new drops.
Bards: Performer's Flourish (finesse weapons use Charisma when it's your best stat), and Magical Secrets now adds damage, damage reduction and health.
Raise Dead, Pact Familiar and Conjure Animals last a little less than their cooldowns (about 65% uptime instead of permanent).
Gnome Cunning: +4% cooldown reduction and +2% dodge.
Vhoruun's Effigy notices when you're cruising: after three clean clears in a row (no death, never below half health) it tells you what the next mode pays.

Still on our list: ranged heroes and summoners (wizard, druid, warlock, necromancer) remain the most forgiving on Medium, and at World Tier 2 the gap between the toughest and the most fragile classes is still wide.
