Okay, so either the Whirlpool Saber is too weak, or the Sand Storm Claymore is way, WAY too strong...Actually, I think it's both.
The Saber is a Post-Skeletron AND Post-Jellyfish weapon that does base 15 damage. The projectile travels about 15 blocks, goes through blocks, and can pierce several enemies. However, the knockback is more of a hindrance, requiring the player to chase the monster they're fighting.
The Claymore is a Pre-EoC weapon that does base 16 damage. The projectile travels...Let's estimate 150 blocks, and can pierce 8 enemies. It also does minimal knockback, meaning it destroys monsters when they stand in a line, like Goblin Army and Old One's Army. Or just standard Fighter AI like zombies.
Was a number mistyped somewhere, or is this intentional? It really doesn't feel like it...
