Core Boss Combat & Stagger Rules
Rule 1: ×1000 Block Multiplier

Regular attacks drain 1-2x stamina. Dangerous boss slams carry a ×1000 block-break multiplier that instantly shatters held shields.

Rule 2: 0.066s–0.15s Parry Window

Deflecting right as an attack lands (0.066s-0.15s) negates block-break, reflects poise damage, and charges Special meter rapidly.

Rule 3: Fixed Threat 1-5 Hazards

Environmental hazards are deterministically unlocked at Threat Levels 1 through 5, unlocking catastrophic arena hazards at Threat 5.

Gilles has 8 distinct moves, 5 of which carry the ×1000 multiplier and break held guard unconditionally. Do NOT hold block against his overhead stabs or running charge — use strict 0.066s–0.15s Parries or roll laterally, and punish his 4-swing exhaustion.
