The Chlorophyte Partisan is a Hardmodespear crafted using Chlorophyte Bars. It beats all of the "standard" ore spears, dealing 9 more damage than the best of the standard Hardmode ore spears, the Titanium Trident. When thrust, it emits a cloud of spores from the tip of the spear at the apex of the thrust, which looks exactly the same as the Chlorophyte Saber's projectile. The cloud travels a short distance in the direction the spear was thrust before fading out, and it is able to penetrate through solid blocks and multiple enemies, but it does not inflict any knockback.
Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount.
Contrary to what its inventory sprite suggests, the Chlorophyte Partisan is actually quite long. Because it additionally has a spore cloud that follows its thrust, the Partisan has a massive range, possibly the second largest (after the North Pole) range of spear-type weapons.
The spore cloud has the same damage range as the spear itself, and is able to deal critical hits.
It can be used to damage enemies through blocks via the spore cloud it emits, but not by the actual spear. Because of this, the user must be at a specific distance in order for the spore cloud to make contact. The cloud will not make contact if the enemy is too close, since it is only released at the tip of the spear during the apex of the thrust.
Because of the damage and knockback, it is a useful weapon against groups of enemies. It can knock back several enemies at once, this also makes it useful for defense.
