Unfortunately it seems he's still bugged. Had 2 runs with him today, the first I lost because of lag, though he did split into 2 before I died, the second run however, he didn't split after I'd got his first incarnation down to zero, the encounter ended, and no drops.
Which is sad. Two T-fangs wasted. Anyway, don't do him till he's fixed basically.
No idea what my toon is now.
