Poenir and Duenir

Keep moving and use Wind Dash for space. Damage Poenir, the lower-health half, in short openings and kite Duenir. Do not retreat into the entrance tunnel at the start: Poenir can catch on the ceiling, pillars or doorway, and reloading fixes it. Patch 1.01.06 rebalanced this fight, so earlier write-ups may describe a harder version.
