Lightning Sigil

Lightning Sigil is a spell added by Electroblob's Wizardry.

When cast it places a trap on top of the targeted block, with a max range of 10 blocks. When a mob or player other than the caster or one of its allies steps on it, the trap disapears, the target takes damage and up to 3 additional enemies in a 5 block radius take  damage.

Wand Range Upgrades increase the placement range and potency from lightning wands increases the damage.
