Brotip for people who are new.
You can do Shift+Left Click to bind elements to your sword, Shift+Right Click for a radius blast thing.
Oh yeah, and ctrl to block. And shields on yourself make you more prone to being knocked down. And QFSAAA is overpowered. And DQRQRQRQR is a good emergency thing (does something like a thousand damage if just fired off, if charged to full, ~10000)
Also the Staff of War is my favourite staff. Double HP + Physical damage resistance + Free arcane bolt every ~5 seconds? forget. Yes.
