The Relic of Ruin's multiple spinning projectiles, which home in on the Super Dummy
when the blades are close enough to them.
The Relic of Ruin is a craftable Hardmode spell tome. When used, it fires out 16 spinning blades in a circle from the player, which home in on nearby enemies. The blades are grouped roughly in pairs, with each pair being varying distances apart, and fly away from the player while synchronously alternating between very high speed to very low speed, rather than a continuous motion. The blades neither pierce nor pass through blocks.
Its best modifier is Mythical.
