This is a thread to answer everyones questions about what happens with stop opp ability and stop opp bonus in the same round. Mods if you find that this guild is clear and helpful, please sticky. I was once a new player who asked this very question and i think having a stickied guide will be helpful.

For the following examples, assume that:
1. the room you are playing in is non-random
2. that neither person has played any pills
3. that all bonuses apply and are active

Take a look at the following round.

Otakool VS Flo

Otakool
power 6
dmg 4
(ability) stop opp ability
(bonus) +8 to attack power

Flo
power 5
dmg 2
(ability) stop opp bonus
(bonus) -2 opp power

Who stops what? Does Otakools bonus get stopped?

The best way (and easiest i've been told, i forget from who) is this! Put all the abilities in a chain of what affects what. Use paper and a pen if you have to. The beginning of the chain is always the stop opp ability or stop opp bonus that has nothing affecting it. This is what the following round looks like in a chain.

(Otakools ability) Stop opp ability ----- (Flos ability) Stop opp bonus ----- (Otakools bonus) +8 attack power

Since nothing has stopped Otakools ability or affected it at all, Otakools ability follows thru and stops Flos ability. Otakool keeps the +8 attack power and wins the round.

Mods i would like to post 2 more slightly different examples but i have reached my character limit. I will wait till this thread gets approved
