The Snapspore Wand is a pre-Hardmodesummon weapon that is dropped from Snaptrappers. It spawns a Snapspore minion that bounces around towards the nearest enemy on screen, when attacking an enemy it has a chance to release a poisonous cloud that inflicts the Poisoneddebuff. The Snapspore minion is like any other minion invincible and will follow the player for an unlimited amount of time, unless the player dies, summons a replacement minion, or cancels the buff. The Snapspore minion does have the ability to phase through tiles.
It's best modifier is Ruthless. While the Mythical modifier has more stat bonuses, those bonusses primarily affect the initial minion rather then the resulting minion. Additionally Minions are not able to deal critical hits on enemies. The only significant advantage a Mythical Snapspore Wand has over a Ruthless one is knockback, though it decreases mana consumption it is not a necessity for a summon weapon as those are mostly used once and then never agian until death or cancelled summons.
