My understanding is that every negative effect needs accuracy if not stated otherwise, stripping buffs falls under negative side

so to that  I guess I am getting at why  there is  not a more specific way to know this when looking at a champion.

or is it  ONLY when written in the description of a champion plain as  daylight  100% chance / we must assume evry negative effect as you state it  will need accuracy?

Thankyou for the comment as I try and   figure out the truth to this and know/understand whenI need to apply accuracy to a champion who has  no Red debuffs displayed  on their skill list

Things that need accuracy:

Applying any Debuff to enemies

Buff Steal or Removal from enemies

Turn Meter Drain from enemies

The only time these things don't need accuracy are when it specifically states so in the description of the skill.

The notable exceptions to needing accuracy on negative effects are the Block Revive debuff and Activating an HP Burn that has already been placed, such as Dreng or Cronham's abilities.

very helpful Thankyou for this clarification..helps me  a lot to better understand this application and  how it works

note that cc effects from gear sets like stun, provoke or freeze do not need acc.
