Not Updated For Current Season
This is not a spam build, just the build that works best for me.
Having RoA for extra HP, MP, and AP makes it a great item.
ArchAngels Staff increases your AP a lot and in the end your overload will be doing more damage than ever.
Void Staff is an extra bonus for the tanks that do have a lot of MR, but you could also just substitute it for something else like banshees, another staff, or will of ancients for some spell vamp.
