But if ye nerf rock you really ought to take a look at Creeping Death as well, because that spell does a ton of damage (ok, it has a long reload, but its basically the same thing as throw rock, just slower and without physics but with way more damage ,p)
Also, while i am writing stuff... you also ought to put a warning somewhere around that region with the shard-nodes, because that is definitely not a level 1 fight.. even if its in level1 region ^^
Also another thing...
Theres a way via rebinding mouse buttons to trigger 5 and more ability slots AT ONCE circumventing timers and literally casting multiple spells with 1 button
And lastly, there should probably be a No Friendly Fire zone in the settlements, because i killed all my guys by accident when i tested a key bind (creeping death...)
