Arrow PrecisionTier SCost 35 | Precision | Select the exact cell you want to land on this turn and fully bypass the random drop mechanic. | Boss fights and rows with 3 or more lethal cells. | The Merchant | Do not spend it on a normal room. Save every Arrow for bosses or mathematically unwinnable rows. |
Bubble DefenseTier ACost 10 | Defense | Grants immunity to the next monster attack you receive. It does not block traps. | Entering high-monster-density rows on a budget. | The Merchant Grid drop | This is the best value item in the game. Carry 2 to 3 whenever possible. |
Sun Potion UtilityTier ACost 7 | Utility | Immediately recharges your Sun Power regardless of cooldown. | Emergency escapes and chaining Sun Power within one biome. | The Merchant | Especially strong on The Lizard because the cooldown is only 2 turns. |
| Offense | Destroys all monsters in one selected row. It does not affect traps or special cells. | Clearing a row for a safe chest pickup or removing the Merchant. | The Merchant | Bombing the Merchant steals all shop items but permanently closes all future shops for that run. |
Cluster Bomb OffenseTier BCost 28 | Offense | Destroys one random monster in each row at the same time. | Thinning a heavily populated board before you choose a row. | The Merchant | Less precise than Bomb, but useful when every row contains at least one monster. |
Pile of Rocks OffenseTier CCost 18 | Offense | Triggers a rockslide from your current position and destroys all cells in the row below you. | Clearing the row directly beneath a safe position you already control. | The Merchant | Situational. It only shines when the row geometry already favors you. |
Throwing Stars OffenseTier CCost 15 | Offense | Randomly eliminates between 1 and 4 monsters anywhere on the current grid. | Cheap board thinning when Bombs are unavailable. | The Merchant | Unreliable targeting keeps it below Bomb, but it is the cheapest offensive tool. |
Flute SpecialTier SCost Special | Special | Play a melody in The Source room to trigger a unique special effect. It breaks after one use. | Triggering one of the strongest run-changing Source-room events. | The Source room | Do not waste it outside the right context. A broken Flute can later be repaired. |
Fountain Bird SpecialTier ACost Special | Special | Repairs a broken Flute and restores it to usable condition. | Setting up a second valuable Source-room use. | The Source room | If your Flute is broken, prioritize finding The Source room before spending attention elsewhere. |
