Weakened
This effect is inflicted by heroes like 
Overlord Executum using 
Void Taunt and 
Void Strike. The effect reduces stats by a percentage, making the affected target less threatening in battle. Specifically, heroes that rely on high ATK and CRIT will have a tougher time dealing sufficient damage. Heroes that rely on defense will find that they are taking much more damage from all sources. When used offensively in battle, it can help a team quickly take down dangerous targets. When used defensively, it can prevent enemies from landing critical hits. 
Shadow Queen Daeris can also inflict the Debilated debuff with her 
Debilitating Shot ability.
