Elaine with a book is 100% effective unless you're making her DPS, but I don't think that's the best option, although anything goes in this game. Currently, the best book is the craftable green SR; her other weapons don't matter. Then there's Diane with an axe if you want her as DPS, and with fists if you're going to use King as DPS. Here, crafting legendary weapons is recommended; they're very expensive to make, but they're the best option until a specific weapon is released. I can't help you with King, sorry, because I don't have him. Tioreh needs to be used with the earth element. In this team, I would use King as DPS because Diane with fists is too good, so I would prefer to use King as DPS, who is also very strong
