I was farming in Jugner Forest, and I decided to see if Panzer was around. I killed a couple of placeholders, and 10 minutes later he spawned.
I healed to full MP and put him to Sleep, debuffed him as much as I could, and healed a bit more. He woke up and the fight started.
I was outmatched from the very beginning. As a RDM30/THF15, he was hitting me for much more than I was hitting him, even with Enfire. Like most NM's, he has a ton of HP, and it was a very, very long fight.
A DRK came up to me at one point and told me to disengage it. I didn't, and fought to the bitter end.
With my HP in the deep yellow, and 1 MP left, I killed him. Dropped a beetle jaw, an insect wing, and 36 EXP, but no Neckchopper.
My most exciting NM fight so far.
