A solo 20-stage roguelike combat event (not tied to normal base actions). You pick generals at Stage 1, advance stage-by-stage fighting Mayan Warriors/Guards/High Priests, occupy totem towers, dispel fog and collect buffs/runes/gold; a final boss is at stage 20. Score sources: kill enemies (Warrior 10, Guard 20, High Priest 40), dispel green fog (5 each), occupy Crescent Totem (20), Typhoon Totem (50), Poisonwood Totem (100); Holy Wrath Rune on Poisonwood gives NO score. High-score loop (author hit 11,190): defeat ALL enemies, occupy ALL towers + as many Poisonwood as possible, dispel ALL fog, and beat the stage-20 boss with maximum troops remaining (nearly 1,000 points of variance) -- requires heavy buff-stacking and healing items, expect ~10 retries from stage 1. Buff strategy: stack buffs scaling with Mayan Gold owned (Ring of the Rhine, Hand of Famine) plus Gold in Fog and Moneybags to snowball gold; run a siege-heavy formation with Unstoppable Force for unwounded wins; avoid Desperate Measures and Hand of Death (block healing); save Blade Rune and Prediction Rune for the last boss. Reset points: stages 1, 3, 8, 14, 18. Buildings: Portal (advance), Mayan Camp (recruit), Life Stream (heal), Calendar Stone (random buff), Mayan Market (buy with gold). For a bot, this is a self-contained combat puzzle -- low priority for an economy-first bot since no base action helps and it needs manual buff decisions.
