Fel Sword

The Fel Sword is an Dungeon Sword that boosts the Healer class' abilities while in dungeons. It can be crafted with a stick and 32 Fel Pearls. It requires 20 to use.

This sword description states that it reduces the healer wish ability cooldown by 10 seconds and increases the healing from the healing circle by 10%. Despite being prominently a healer weapon, it can still work extremely well in a budget berserker's build.

When the attack damage is upgraded, it is not displayed. (More info needed)

Essence Crafting
This weapon can be upgraded with wither essence.

Trivia

 * This is one of 6 Items that take the form of a Stone Sword, the other five being the Adaptive Blade, the Earth Shard, Conjuring, the Wither Cloak Sword, and the vanilla Stone Sword.
 * The +100 damage buff does not show as a weapon stat and does not stack with catacombs levels or dungeon item stars. It does, however, exist and increase damage (making a maxed Fel Sword stronger than a non-gilded 50 mil Midas' Sword outside dungeons).
 * The healing circle healing buff gives approximately +100% healing instead of +10% healing.
 * The 10 second wish cooldown was bugged and did not work properly until the 0.11.3 skyblock update
 * This sword needs to be held for the healer buffs to work.
