Worldslayer Technique

Declare a mythic weapon technique tied to a duel, army, tyrant, monster, fortress, artifact, war, or impossible strike. Define its principle with the GM: the cut that ends a siege, the arrow that finds a hidden god, the stance that holds a bridge alone, or the blow that breaks an empire’s weapon. It can be opposed only by Tier 10 martial mastery, divine intervention, artifact protection, or a story condition set when declared.
