Underworld Mason

Liberate both underworld chambers by clearing masonry rows to damage their guardians. Move and rotate a two-stone slab, then Drop at its ghost. A clear deals your Power per row; a nonlethal drop also triggers the guardian’s forecast attack, even if it cleared a row. After each nonlethal clear choose one boon: Power increases damage up to three, Shield absorbs four future damage, or Mend restores three hearts up to six. Boons cannot be taken without earning a clear. Defeating the first guardian opens a new chamber while carrying your hearts, power and shields forward. The second guardian strikes harder, so prepare protection before entering. A killing clear prevents retaliation. Buried spawn or zero hearts ends the run. Keyboard: Tab and Enter/Space operate buttons; R restarts.
