Kreknorite ore drops Kreknorite chips(krekno chips for short). Krekno chips are used to craft Kreknorite Armor and a Kreknorite sword. The armor causes you to be completely immune to fire, allowing to dance in fire and swim in lava (great for the nether don't you think). The sword has a unique ability that sets fire to whatever mob you hit with it. Kreknorite is the strongest material you can make items out of in this mod.
