So my team is raiding the trex.where all level 15
.we have 3 bleeders and 1 healer we use bleed at first round damage is 2500 and bleed is 6800 then round 2 its finished we then we know trex will do his shields and increase attack we use nullify cuz we have 2 suchotator then we finish it in round 5 or 6 if you use one bleeder the bleed will be 1600 when full level suchotator. so its best to use it when doing epic raids
