Wow, just took a look at the Sword Burst cantrip from SCAG, and... Wow... This thing has the potential to do 3rd level Fireball damage* as a cantrip?!?!? How did this pass the Whoa Police?!?!?
*the tank EK is wanting to take it. If he is surrounded by 8 goblins (entirely possible and likely), that's 8x 1d6 damage** with Dex save
**I am aware that a Fireball would do 64d6 to the 8 goblins... BUT, if the EK drops a Fireball on the 8 goblins surrounding him, then he takes Fireball damage too. Not to mention that he just expended a 3rd level spell slot, a significant resource. Sword Burst is a freakin' cantrip! At-will, no resource, eat ghost blades and suck it goblin scum...
