Drowning Beacon event art, Slay the Spire 2

Drowning Beacon

Crossing a dreamscape of rocks and still waters, you emerge to face a sinking lighthouse emitting anti-light.

You can bottle up the eerily-glowing water that has pooled here or climb up the dilapidated structure to retrieve the lens.
Using a nearby bottle, you calmly scoop up the glowing liquid as the lighthouse peacefully sinks into the mud.

Good thing you weren't in there.
You climb to the top of the lighthouse, unnerved by its steady sinking.

Upon reaching the lanthorn room, you start prying off the lens as the anti-light saps your vitality!

Finally, you wring it free; the lighthouse stops sinking.

Which option to take

Bottle

PotionGlowwater
  • Bottle when the deck already has its block or your HP pool is small; the potion is a strong burst turn for exhaust or draw decks.

Climb

Our pick
RelicFresnel LensMax HP−13
  • Climb in Act 1 if your Max HP is healthy: every block card you draft from here on comes with +2 Block, a run-long buff for a one-time price of 13 Max HP.

How it plays

  • Bottle: offers a Glowwater Potion as a reward, Exhaust your hand and draw 10 cards.
  • It needs a free slot and can be skipped.
  • Climb: lowers your Max HP by 13 and grants Fresnel Lens.
  • Fresnel Lens: whenever you add a card that gains Block to your deck, it is enchanted with Nimble 2, so every such card arrives with 2 more Block for the rest of the run.
  • Cards already in the deck are not touched.
