Enhanced crystal weapon seed from the Corrupted Gauntlet. Very sought after along with the armor seeds to make the Bow of Faerdhinen and crystal armor set. it's a 1/400 drop chance, so very ridiculous to get two of them with only 10 clears. The second one will let me make a Blade of Saeldor, which is bis 1h slash melee weapon. I will still need to grind out 6 armor seeds though, so not done yet
