Build Use

The base buff changes with the weapon in your hand. Sword applies Bleed on Affinity hits, Spear ignores 12.5% Physical Defense, Dual Blades boost your next Martial Art Skill after a Perfect Dodge, Mo Blade adds Critical DMG to Charged and Parry Counter Skills, and Heng Blade buffs Varied Combos after a deflection.

The breakthroughs are all about the Dual-Weapon Skill you use when swapping weapons: 30% more damage, a 20% speed boost for you and a 20% slow on the target, and 10 Endurance back per cast. Tier 6 keeps your previous weapon's mastery active for 10 seconds after the swap, so you briefly get both weapons' bonuses. Tiers 2 and 5 add Max Bellstrike Attack and Bellstrike DMG Bonus.

At Tier 6, swap with a Dual-Weapon Skill right before your burst so the mastery from your first weapon is still running alongside the new one.
