Summary

REGENT A0 run died on floor 7 to a dual-Nibbit encounter. The early game went smoothly — cleared floors 1-4 with only moderate chip damage — but the Cubex Construct on floor 5 was a long fight that dropped HP from 54 to 39, and the Vine Shambler on floor 6 further depleted HP to 25. Entering floor 7 at 25 HP against two Nibbits, one of which rapidly stacked Strength, proved fatal. The Nibbits buffed to Str 2-4 while the agent scrambled to kill one; after eliminating the weaker Nibbit at the cost of most remaining HP (6 HP left), the surviving Nibbit attacked for 16 against only 10 possible block. The deck's Forge/Furnace/Sovereign Blade synergy was strong offensively but provided no defensive scaling, and without a potion or rest site available, the run ended to cumulative combat damage.

Bridge findings

• handIndex shift after PlayCard — After every successful PlayCard, hand indices re-pack. Issuing a subsequent PlayCard using a cached handIndex from before the play frequently targeted the wrong card (e.g., played Furnace when intending Defend, played Venerate when intending Summon Forth). This is documented behavior in SKILL.md but caused 5 error responses and at least 2 mis-plays (wrong card played that consumed energy). No stall resulted; the agent recovered each time by re-reading state.

None observed beyond the expected hand-shift issue.

Decision log highlights

• Neow choice: Booming Conch (option 1) over Lead Paperweight and Cursed Pearl. Picked for elite-combat value (draw 2 + energy at elites). No elites were reached before death, so the relic provided no benefit this run.
• Floor 2 card reward: Furnace — 1-cost Power, Forge 4/turn. Strong synergy pick for the Forge/Sovereign Blade engine. Performed well in practice.
• Floor 3 card reward: Solar Strike — 1-cost 9 damage + gain 1 star. Solid attack upgrade over basic Strike. Used effectively in multiple combats.
• Floor 5 (Cubex Construct): Used Flex Potion + Monologue combo for a 27-damage burst turn. Effectively halved the enemy's HP but the prolonged fight cost 15 HP total.
• Floor 5 card reward: Summon Forth — 1-cost, fetch Sovereign Blade + Forge 8. Strong synergy with Furnace. Used successfully to close out the Vine Shambler fight.
• Floor 6: Skipped card reward to keep deck thin at 13 cards while at low HP. Defensible given the priority was reaching a rest site.
• Floor 7 map routing: Only one available node (Monster), no choice. No rest site was reachable before the fatal encounter.

Notes for maintainers

• The agent experienced no tool leaks (no MemPalace, webfetch, task/sub-agent, or MCP tools were available or used).
• All stat lookups came from the allowed docs/data/eng/*.json files; the glossary was consulted for the "Forge" mechanic definition.
• The list-cards.ps1 tool threw PropertyNotFoundException on cardType when inspecting card reward options — the field does not exist on cardRewardOptions.cards[i].card. The agent worked around this by reading read-state.ps1 -Filter full instead. This is a minor tool bug, not a bridge bug.
• Five PlayCard commands returned status=error due to stale handIndex targeting after hand re-packing. The agent corrected each time by re-reading combat state. This is documented expected behavior but caused measurable inefficiency at ~4% of total commands.
