The Survey
A board of 31 nodes in the Cartographer's Lodge that shapes what drops where. Loot and maps only: it never touches your hero's stats.
Earning points
- You earn a Survey point for each tier of a dungeon you chart Pristine. A Pristine clear above your best tier there pays that tier and every tier below it you had not charted yet, so running only high-tier charts loses nothing. 25 dungeons × 16 tiers is the ceiling.
- The board opens at Lodge level 4, and the whole thing costs 76 points.
- Five act regions, each a short chain where every node needs the one before it; only that act's charts and breaches feel them.
- The Ember region in the middle works everywhere and opens as you spend points. A locked node tells you how many more it needs.
- Favoured Dungeon: pick one dungeon of the act and its charts drop twice as often.
- The board keeps a tally of dungeons charted Pristine at Tier 4, 8, 12 and deeper.
- Pristine clears at Tier 8 and deeper can also drop a Survey Shard: an Emberforged roll in the slot you choose.
