If anything, that’s the only decent part of Allanon. Similar to Argos, he doesn’t regen upon dying since you spawn so close to the arena. It drains your drachma, but it makes it impossible to fail him as long as you can get a couple hits in. The easiest way to beat him is to just force out damage and to keep distance.
he did that to me several times
even regeneration when i actively hit him not even 3 seconds
i hate them
He never went back up to full when I first fought him. Maybe it’s just me, though.
