Debuff

Seal

There are two versions of this debuff: Seal and Master Seal.

The Seal debuff blocks effects from Gear Sets and Masteries, except stat boosts granted by Artifacts and Accessories, as well as Masteries that only boost stats like Blade Disciple, Flawless Execution etc.

Master Seal is an enhanced version of this debuff, which additionally blocks the effects from Blessings, Relics, and Gemstones, except stat boosts.

The Seal and Master Seal debuffs don't block effects that were activated before these debuffs were placed.
