I don`t know what squad or friend I use to defeat Grahdens and need help. What is beether a mono water squad (guardian  snown queen signas, ice warrior karl, anima axe king mariudeth, oracle tyrant goddes phee) with spear king raydin as a leader (all the 6 on the squad with sbb) or a rainbow squad (lord bordebegia, oracle melchio, breaker spear king raydin or lord mech god gribe, anima maruideth) with inferno sword logan as a leader (all this squad have bb and sbb to max)? And what is better as a friend grahdens on max lvl and max bb or raydin with bb 7 and lvl max or atro with sbb and lvl max? Ps: I don`t have a healer.
