I'm still quite new to the game, trying to figure out what happened here. Where did the plasma beam come from? Did it fire from your wand and the gold nugget deflected it?
Yup, the plasma beam came from my wand but the gold nugget itself wasn’t the thing that reflected it back towards me. The wand I was using had a spark bolt trigger with a bunch of plasma beam spells tacked on after it. Spells that have the trigger property will cast spells after it in a reflected angle after hitting something. When I had used the wand and the spark bolt collided with the gold nugget, it cast all the plasma beams I had added into it but aimed towards my direction.
