Summary

NECROBINDER A0 cleared Act 1 (Overgrowth) including boss Vantom on F17 via Doom-stack kill (HP 35/66 post-boss). Carried 158g into Act 2; picked Pael's Blood relic at F17. Ran F18 Tunneler (clean win), F19 dual Bowlbug (Imbalanced stun route), and F20 Ovicopter+Eggs (Reap+ doom-kill of Ovi → Hatchlings flee as Minions). Took Danse Macabre + Heart of Iron from F20 reward, then Shop F21 (bought Power Potion 51g + card removal 100g, removed a Strike). F22 was a Spiny Toad (116 HP, Thorns x5, Spike Explosion 23). Heart of Iron at combat start gave Plating x7 (worked correctly after one revision lag) and Danse Macabre x4 power up — but Spiny Toad's Thorns made every attack costly, and the second-turn Tongue Lash plus a third-turn Spike Explosion punched through Plating decay. Died T3 on F23 (renumbered post-shop) at Toad 50/116 HP with 41 Doom stacked but unable to bridge the 9-HP gap before lethal damage. Death floor 23, gold 23, halt_reason death.

Bridge findings

• UsePotion for "AnyPlayer"-target self-buff potions does NOT show power on player immediately: Heart of Iron (target type AnyPlayer, applies Plating to Necrobinder) returned ok=true, slot consumed, but combat.player.powers was empty on the immediate read. After playing one card (Danse Macabre), the next state read showed Plating x7. Same lag pattern as run17 / run21 potion findings, but specific to powers-on-player vs block-on-player. Workaround: issue any cheap card play after UsePotion, then re-read. (Run-confirmed F22 T1.)
• Gambler's Brew opens a handSelect overlay; the cardHandIndices parameter to UsePotion is ignored. Tried UsePotion slotIndex=0 cardHandIndices=@(0,1,3,9) — bridge accepted (ok=true), potion consumed, but actual selection had to be made through the resulting handSelect modal (mode=SimpleSelect, requireManualConfirmation=true, cancelable=false, prompt "Choose any number of cards to replace."). Resolved with HandSelectCard handIndex=N per card + HandConfirmSelect. Note: the discard-and-redraw effect was not visible — hand cards looked identical after confirm. Possibly the modal closed without re-drawing. Either the potion silently failed, or the hand was only redrawn on a future state delta we missed. Recommend tools/peek-handselect.ps1 for inspection. (Run-confirmed F20 T3.)
• SelectReward rewardPosition=N with N=position of a Potion reward sometimes opens the next reward (CardReward) instead. F20 rewards list: [Gold(pos=0), Potion(pos=1), Card(pos=2)]. After rewardPosition=0 (Gold) succeeded, rewardPosition=1 returned ok=true msg="opened CardReward sub-screen (position=1, RewardsSetIndex=5)" — i.e. it opened the Card sub-screen, not the Potion. Picked the Card (SelectCardOption cardIndex=2 → Danse Macabre), and the Potion remained at pos=0 for a follow-up SelectReward rewardPosition=0 that correctly added Heart of Iron. Likely the bridge's rewardPosition indexes against the live state.rewards array (which mutates as rewards are consumed), not against the original positions at room entry. Agents should re-read state.rewards after each SelectReward and treat positions as ordinal in the current list, not stable IDs.
• SelectCardsInGrid parameter name is cardIndices (NOT indices). First attempt with indices=@(0) returned 'SelectCardsInGrid requires 'cardIndices' (int[])'. Retry with cardIndices=@(0) succeeded for shop card removal. Worth noting in SKILL.md command table — currently shown as Indexes in some prior-art references.
• ShopPurchasePotion is not a valid command name. Use Purchase category='potion' index=N instead. The Purchase command also accepts 'character_card', 'colorless_card', 'relic'. (Confirmed live; matches SKILL.md line 374.)
• Danse Macabre power displayed as x4 despite description saying gain 7 Block — the in-game block actually granted per 2E+ play was 4 (Severance gave +4 block, not +7). The description text in state appears to be the upgraded value (when card is currentUpgradeLevel=0 the description might still show upgrade preview text). Worth a bridge schema bug for description vs effective stack mismatch on Power cards.

Decision log highlights

• F17 boss Vantom (Act 1 boss): Won via Reaper Form on T1 + 5-turn Doom stacking. Slippery x7 didn't reduce Doom application (Doom = tag, not damage). HP 35/66 post-fight, took Pael's Blood relic.
• F18 Tunneler: clean kill, HP 64/66.
• F19 dual Bowlbug (Rock Imbalanced + Nectar): T1 Defend fully blocked Rock's 15 → Stunned (Imbalanced confirmed: full block = stun next turn). Drain Power+Unleash+Fetch on Nectar → Nectar 6 HP. T2 Wisp+Strike kill Nectar, Reap+ Rock to 6 HP. T3 Strike kill. HP 62/66.
• F19 reward: Reave over Lethality (Ethereal risky w/ 3E Reaper Form competition) and Debilitate (no Vuln/Weak synergy).
• F20 Ovicopter+Eggs: T1 Wisp+Reap+Unleash → Ovi 79. T2 4-card AoE-and-target volley + Blight Strike applies 8 Doom; took 14 face dmg. Eggs hatched. T3 race: Severance + Soul + Fetch chipped Ovi to 34. Tried Gambler's Brew to refresh hand (fizzled in a confusing way — see findings), then Reap+ to 1 HP at T4 → Doom 8 ≥ 1 → Ovi died at EoT, Hatchlings (Minion) fled. HP 13/66.
• F20 reward: Picked Danse Macabre (synergy with deck's 2E+ cards: Reap+, Reaper Form, Severance) over Pull Aggro+ and Poke. Took Heart of Iron potion.
• F21 shop: With 174g, bought Power Potion (51g) + card removal of a Strike (100g). Skipped Defile (Ethereal punish), Powdered Demise (couldn't fit), and unaffordable relics. Ended with 23g. Card removal slot is the highest-value purchase at this gold level, but the trade-off (no health-restore option) hurt later.
• F22 Spiny Toad T1: Heart of Iron → Plating x7 (post-lag) + Danse Macabre power on. Blight Strike + Grave Warden + Fetch → 11 dmg + 8 Doom. End of turn block 18 + 7 plating tanked Toad's Buff.
• F22 T2: Toad now had Thorns x5 + Spike Explosion 23 incoming. Wisp + Defend×2 + Severance plan: Defends first to soak thorns (5), Severance (13 dmg + 4 Danse block), end turn block 9 + 6 plating = 15. Took 8 face from Spike Explosion → HP 7.
• F22 T3: Reap+ Toad (3E, 33 dmg → Toad 50 + 41 Doom from prior 8 Doom stack) + 4 Danse block + Soul (drew 2 Defends but no E to play). End turn block 4 + 5 plating = 9. Toad 17 dmg → 8 face → HP -1, DEATH.
• What I should have done T3: Played Reaper Form (3E) instead of Reap+ would have been wrong (no damage, dies harder). The real mistake was T2: should have used Power Potion that turn for Shroud (2 block per Doom apply) — would have stacked massive block alongside Doom. Or skipped Severance T2 entirely (kept Plating tempo, fewer Thorns triggers). Tank-then-kill plan against Spiny Toad needs to avoid attacking until block dominates Thorns.

Notes for maintainers

• Heart of Iron (Plating-granting potion) needs a targetIndex/targetSelf story. The targetType: AnyPlayer confused me — I used slotIndex=0 alone and the potion still applied Plating to me eventually, but the lag made me think it had fizzled. Potions with targetType=AnyPlayer should either auto-target self or document the expected targetIndex (Osty vs player).
• cardHandIndices parameter to UsePotion for Gambler's Brew: either honor it (skipping the modal) or remove it from the schema. Currently it silently no-ops then opens the modal anyway — worst-of-both behavior.
• state.rewards[] mutates as rewards are consumed and rewardPosition refers to the current position not a stable ID. Either expose stable position (already in payload but ignored by bridge) or document the indexing rule prominently.
• Plating decay: confirmed x7 → x6 → x5 across turns 1→2→3. Block grant per turn matches stack. Working as designed.
• Add to SKILL.md command table: SelectCardsInGrid parameter is cardIndices, not Indexes or indices.
