Relics of the Spire brings Slay the Spire 2's relics into Starbreed's rail-shooter levels.
Shoot down enemies to open Spire relic rewards: pick 1 of 3 real Slay the Spire 2 relics. Their icons, names and descriptions are read straight from your own Slay the Spire 2 install.
Every relic changes your ship: Vajra and Shuriken boost your shots, Anchor shields you as each level starts, Bag of Marbles weakens bosses, Kunai speeds up your guns, Strawberry, Pear and Mango add hull, Orichalcum repairs you while you dodge, and more. 19 relics in all.
Relics stack across your run. Clear a level for another reward, but if your ship goes down the run ends and your relics are gone, just like the Spire.
Your relics are shown along the top of the screen while you fly.
Single player. You need both Starbreed and Slay the Spire 2 installed; nothing from either game is included in the download.
