Cursed Spirit's Blade

The Cursed Spirit's Blade is a sword added by Thaumic Tinkerer. It has 950 points of durability and deals 10 points of damage (5 hearts) but will apply a one heart damage every time to the holder. When blocking with this sword, it will negate all damage but will deal a 1.5 heart damage to the holder. When shift right clicked, it will activate essentia harvesting mode, which - when a mob is killed with this sword - will drop the aspects of the mob in form of Soul Aspects. Lastly, when holding the sword, the player will gain 25% more speed.
