Marks: every Peril, Boon and Twist

All 43 Marks you can put on a chart in The Ember Depths: what each Peril, Boon and Twist does, its Danger, and how the printed rewards are worked out.

Marks are how you set a chart's difficulty yourself. Perils make the dungeon harder and each carries a Danger number; Boons pay extra and cost you nothing; Twists change the shape of the dungeon. The chart prints its total, such as "Danger 4: +32% rarity, +24% materials, +16% chart drops, +20% experience", before you step in. There are 30 Perils, 7 Boons and 6 Twists.

What each point of Danger adds (printed on the chart)

Per Danger point	+8%	+6%	+4%	+5%

Rules

4 Mark slots, 5 with a Survey Extra Mark Slot; the corrupted Mark takes one.
A chart that drops carries 0 to 2 Marks; you add the rest at the Lodge with Ember Ink (a random Mark of the ink's kind) or a Scribe's choice (pick one of 3).
A chart never holds the same Mark twice, and only one "every elite is …" Peril.
Some Perils can only arrive through a Scorch, as the chart's corrupted Mark (Glass Cannon, Dry Flasks, Twin Champions, Vengeful Dead). A corrupted Mark can't be erased, but it multiplies every reward line by 1.5.
Where the Mark echoes a Rite or Wager rule (the Horde, Quickened, Emberfury and the rest) it works exactly as it does there.
