infernal armor set

[Pieshaman]

some days ago I read someone said you need only 2 infernal irons for karlach upgrades,
but I just found out if you talk to dammon again and have more , he will make you nice stuff from it.
I had 5 infernal irons on me and did the karlach upgrades. the other 3 are now an infernal heavy armor, gloves and a helmet. So don't just sell the surplus iron to any vendor, give them all to Dammon

I dont know if he can make even more, I will try if I find more iron.

Interesting. My game glitched. By the end of the game I had about 6 infernal irons and Dammon would just take mine and give nothing back lol.
