Flamestrike: Casting time reduced by 33%. Deals increased damage to targets unaffected by Burning. (x3 or something like that, good burst after switching to fire, punishes cleanse spam and condi immunity)
Shatterstone: Radius reduced by half, now pulses 1s of Chill every second, twice before exploding. (Balanced by very small AoE, opens up nice tactics, picture whack-a-moling someone XD. Half radius is consistent with the animation also)
Arc Lightning: Is now unblockable. (Why not? It needs a buff and this would be better than straight damage, scepter is already on the strong side when it comes to damage despite the weak AAs)
Stone Shards: Now blocks up to 3 projectiles directly in front of the player during the second half of the casting animation (3/4 seconds, happens just as the stones are thrown, great thematically and is a counterplay skill, yay!)
Dust Devil: Now also slows for 1 second.
