Summary

Silent A0 run died at Floor 8 to Bygone Effigy Elite (127 HP, Slow, Str-scaling). The run was proceeding well, with the player obtaining Booming Conch from Neow and drafting strong AoE (Dagger Spray x2, Blade Dance) and mitigation (Piercing Wail). At Floor 7 Shop, the player purchased Footwork and a second Piercing Wail, leaving 2 Gold.

Entering the Floor 8 Elite combat against Bygone Effigy with 36/70 HP, the player utilized Dagger Sprays and Piercing Wails to mitigate the Effigy's heavy 23-damage attacks. On Turn 9, the player was at 3 HP and the Effigy at 29 HP. The player attempted to use Explosive Ampoule and Liquid Bronze to secure the kill. However, the player incorrectly passed targetIndex: 0 to the UsePotion command for Liquid Bronze (which targets AnyPlayer), inadvertently granting 3 Thorns to the Bygone Effigy. When the player subsequently played Dagger Spray (which hits twice), the enemy's Thorns dealt 6 damage back to the player, causing immediate death.

Bridge findings

• SelectMapNode requires col and row parameters, not just nodeCol or col.
• UsePotion requires slotIndex and targetIndex.
• CRITICAL: Potions with targetType: AnyPlayer (like Liquid Bronze or Mazaleth's Gift) will apply their buff to the enemy if targetIndex: 0 is passed! The player must carefully check target types. tgt=AnyPlayer means the potion can target the player OR the enemy. Passing targetIndex: 0 targets the first enemy, not the player. To target the player, no targetIndex should be passed, or it must be specifically formatted for the player.
• SelectCardInReward is not valid; the correct command is SelectCardOption with cardIndex.
• cardRewardOptions can be accessed via read-state.ps1 -Raw, but extracting the JSON in PowerShell requires care with quotes and stdout pollution from autopilot-lib loaded.

Decision log highlights

• Neow F0: Chose Booming Conch.
• F1 Reward: Took Dagger Spray for early AoE.
• F2 Event (Whispering Hollow): Exchanged 29 Gold for 2 Potions (Explosive Ampoule, Mazaleth's Gift).
• F3 Reward: Took Blade Dance.
• F4 Reward: Took Piercing Wail.
• F6 Reward: Took second Dagger Spray.
• F7 Shop: Bought Footwork (75g) and Piercing Wail (48g), perfectly spending 123 of 125 Gold. Excellent shop execution.
• F8 Elite (Bygone Effigy): The player correctly identified that playing cards increases the Slow multiplier, and optimized card play order to maximize damage. However, the fatal mistake was misinterpreting targetIndex for beneficial potions, buffing the Elite with Ritual and Thorns, leading to death-by-thorns.

Notes for maintainers

• The UsePotion command behavior where targetIndex: 0 applies a player-buff potion to an enemy is extremely dangerous and counterintuitive if the user assumes 0 means "self" or "default target". A warning in SKILL.md about AnyPlayer potion targeting would prevent this.
