Ice Barrage

The Ice Barrage is a craftable post-Moon Lord wand that consumes Blood Runes as ammunition. It creates a circle of energy around the cursor which collapses inwards, dealing a great deal of damage to any enemy within the circle. After that, it creates four large blocks of ice which fire snowflakes at enemies, eventually shattering. The center of the spell attaches to nearby enemies that enter the field.
