At a point you choose, you create an invisible particle of antimatter surrounded by a magnetic field. When triggered by creature passing withing 5ft, it explodes area 20ft radius, causing 5D4 damage in each of the following types; Fire damage(1d4),  bludgeoning damage (1d4), Lightning damage (1d4), Poisoning damage (radiation) (1d4) and Necrotic damage (1d4), unless creature is immune to a certain damage (remove 1d4 for each immune damage).

at Higher levels increase in particle, damage and area; L7 = 2 particles & D6 & 30ft area. L8 = 3 particles & D8 & 40ft area. L9 = 4 particles & D10 & 50ft area.
