Item Effects

Item Effects are special effects that happen when your weapon strikes an opponent. There are two ways to add special effects to an item: Effect Items and Potions

Effect Items
Main article: Category:Effect Items

Effect Items are items associated only with adding a special effect to a weapon.

There are currently four:

Red Hot Piston - Inflicts [http://terraria.gamepedia.com/On_Fire! On Fire!] to enemies on hit. Lasts three seconds.

Poisoned Piston - Inflicts Poisoned to enemies on hit. Lasts seven seconds.

Crystal Cog - Has a low chance to heal you for 20 Life when striking an enemy.

Life Fruit - Has a chance to heal you for 5 Life when striking an enemy.

Potion Effects
There are many potions that can be used to add an effect. However; neither Hunter Potion nor Spelunker Potion can be used for this purpose.

When adding a Potion to an effect slot, the effect will last 2 seconds by default. The exceptions are Regeneration, Mana Regeneration, Shine, Water Walking and Gravitation which last 5 seconds each.

Healing Potions
Adding Healing Potions to the slot will make the weapon heal you upon striking an opponent, provided that you are not under the effects of Potion Sickness.

All such healings have had their effect reduced by 10 life, though, and coupled with the fact that they provide Potion Sickness for 80 seconds, they are far from optimal. However, this effect does not consume healing potions, so it may still be worthwhile.
