Also note that since Triton has fast mana, his special will be ready before Kiril and Grimm. At this point you have the choice of using his special before of after Kiril and Grimm. If you use him before Kiril and Grimm you will lose out on damage because Grimm’s defense down and Kiril’s attack up, thus making him a less formidable sniper but Kiril’s heal will become a whopping 67%. But if you do no need that much heal, it would be better to fire him after Kiril and Grimm.
EDIT: I stand corrected. Triton’s 39% increase does not stack with other healers but increases the heal percentage. So Triton + Kiril will give 0.28*1.39=0.39, that is 39% heal and not 67% as I previously mentioned.
