Heroic dungeons

Beat a dungeon once, then light its Heroic Sigil for a harder, richer run.

How it works

Each dungeon has a Heroic Sigil by its first floor's way in. It opens once you've beaten that dungeon's boss and reached its level.
On heroic, every monster on the dungeon's floors has 80% more HP, hits 35% harder and has +6 defence. Their names start with “Heroic”.
In return they give 60% more XP, roll better loot, and drop marks (Heroic Mark): the boss gives 12, an elite 3, and other monsters one now and then (30%).
Heroic lasts while you stay on the dungeon's floors. Leave, and it switches off; light the sigil again next time.
