For Tome of Pain, I found it very enjoyable to instantly kill minions using its max wis build. Its effectively a mini nuke in your pockets.
While I never tried Necronomicon, it might be fun to try to hit the most enemies with it. Maybe with a close range wand, you pop the tome and run behind it as enemies get cursed then killed by your wand? Just saying.
T-Pain got buffed
I challenge that statement. No weapon can cover a radius of 9 tiles instantly, except bulwark which is anything but instant and only has a range of like 3 tiles.
