Seraph Towers have to be one of the worst events I have ever tried to do. I haven't even beaten one fully yet. It is too chaotic and if even one enemy is near the tower barely any orbs drop. Plus sometimes there aren't even enough people to beat it. The power cap on it made it impossible anyway for the first few days. I think I'm giving it a pass and will instead focus on bounties. It's all I even can do at this point.
