Scrolls

From Shaiya Wiki

Scrolls are one of the few ways a character can dispel any ill effects (known as debuffs) they are suffering from, another way is to use a Potion. When your character is affected by one (or more) of these debuffs, a blinking white icon will appear in the buff-debuff area in the top middle of your game screen.

You can either wait for it to expire as they all have a limited duration, or use a scroll to end the effect immediately. Each scroll cures one specific condition that is currently affecting the character and all instances of that condition if the character is affected by multiple debuffs that cause that condition.

Example : If a character was affected by both Silence Blow and Halt Kick, a single Silence Cure scroll would end both effects since they both cause the Silence condition.
