I was trying out tinkers construct and saw that i could make a sword blade from the blue slime but it dosent work, i cant smelt or just put it in the part builder. how do i make it?
1. Your avatar, when smallified in the forum, looks like Pewdiepie. I was about to not click because of that.
2. Blue slime is horrible for sword blades, it gives no damage.
3. Look through Materials and You, it'll tell you exactly what to do with slimeballs and blue slimeballs to make them into crystals, those can be used to make parts.
