First of, thank you very much for answering.
Also how do i go about getting a cognitor mask ?
Is Crimbo limited to a time of year ( does the game read my computer date&time) or is it an event that happens normally trough playing ?
the stones (the diamond shaped thing) is an attack rune or something, I forgot the name. It can be used to damage and kill enemies by holding your attack button until you see the charging animation with black particles. Each hit deal 1 damage. You can also get an equipment that will make your basic attacks deal damage, like the claw, the knuckles, the boxing gloves, etc
