Borrowed Power can no longer be repaired and sells for a flat 20 gold. The Fallen Hero now appears from your second run onward.
The blackout is fightable now. Its mobs take damage instead of ignoring you, but they never flinch and have ten times the health. You can fight. You cannot win.
Keys now survive an ascension.
Lighting: obelisk fire and burn trails no longer go black outside your light; dark rooms actually darken the walls and monsters instead of just the floor; behind-wall enemy outlines only show inside your light; the trader's shop is lit like the camp.
The spectator wisp is a proper ghostly orb now bigger, paler, trailing and its light finally lights walls and enemies instead of bare floor.
Fixed: continuing a run saved on a trader stage killed the shard-energy clock for the rest of that run: no strip, no blackout, no light shards.
