Perfect Strike (Ex)
Replaces: Spell Recall
At 4th level, when a kensai hits with his chosen weapon, he can spend 1 point from his arcane pool in order to maximize his weapon damage. Don’t roll for damage—the weapon deals maximum damage. This affects only the weapon’s base damage dice, not additional damage from sneak attack, magical weapon properties, spellstrike, or critical hits.
If the kensai confirms a critical hit, he can instead spend 2 points from his arcane pool to increase his weapon’s critical multiplier by 1. This ability replaces spell recall.
