You used a soul boost, those are pretty much useless, except for the incinerate one. That one is tolerable. I really don't like this month's side quest. Spend energy to get useless soul boost, and MHC shards, high chance of a 3*. Then do annoying fights that requires a specific roster to counter or pay the price of using soul boost to get around the nodes. The concept was good, they could have left out the negative effects of soul boosts, and heal block is pretty annoying but not too bad.Hope next month is better
The boosts suck for this event unless you can quake and shake with them or can slow debuff them. Otherwise, they don't really help most of the time because you're trading DOT for unstoppable if you don't have natural immunity or an unstoppable counter. Best option is to bring the right DOT counter(s) for the path and another counter for the boss. Ghost is MVP for this event cause she'll phase them and use that to return the damage and burst them down fast.Colossus handles incinerate, cold snap and bleed paths and Corvus can do most of it too. Doom or warlock for shock and there are several poison and bleed counters (or robots for both). Void is good for incinerate too. This one is a bit roster dependent. Probably the worst boosts we've seen in a long time.
