You *CAN* get ridiculously high dps in "vanilla" Ars.. but you have to enable features turned off by default and the resulting 200k+ projectiles all dealing damage will freeze your PC for a good 10 to 20 mins while it resolves itself.

So all I did was create a few custom spells and changes to other associated mods that allow you to sort of "compress" spell projectiles down into more powerful forms..

if you look at that image to the right (as you look at it) of the dummy over the water you can see a single lone projectile that somehow missed (despite being homing) and it'll travel until it finds a poor helpless sheep/creeper/spider/villager to lock on to and absolutely demolish XD
