Prismalline

The Prismalline is a craftable Hardmode non-consumable dagger that is an upgrade to the Crystalline. It shoots a piercing projectile that is affected by gravity and cannot pass through tiles. Shortly after it is thrown, it emits 5 copies of itself in a random spread, some homing and some non-homing. Copies that home in deal 110% of the original projectile's damage; copies that do not home deal 75% of the original projectile's damage.

Performing a stealth strike with the Prismalline causes the resulting dagger and its copies to explode into 2-4 and 1-3 prism shards respectively. Additionally, an extra dagger copy is spawned, all dagger copies will home in, and will deal 115% of the original damage instead of 110%. Each shard from the main dagger will deal 50% of the weapons base damage, and shards from the dagger copies deal 33.33% damage. The main projectile inflicts the Eutrophication debuff for a short time.
