The Slime Spiker is a trap sentry weapon. It fires once every 60 frames. 5 needles are fired up at random velocities, each one capable of dealing the weapon's listed damage. It has a 33% (50%) chance of being dropped by King Slime.
This weapon benefits from the player's sentry speed, able to fire faster than its default firing speed.
Its best Modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the sentry's damage. Additionally, sentries cannot deal critical hits under normal circumstances. The only significant advantage a Mythical Slime Spiker has over a Ruthless one is knockback.
