I think Amdusias using explosing arrows! Or maybe it was fireball ... not sure.
I didn't make use of my creature. Maybe I used Summon a Demon, that can be, but also not sure I did.
If I remember good Amdusias his weakness is a lower melee resistance (??)... so take your best melee weapon, drink a healing potion and go quickly to Amdusias and attack with your melee weapon!
Like Raze said: on that moment Amdusias takes his sword, so no more fireball or explosing arrow he use...
Success!
