ToME: the Tales of Maj'Eyal

Decided to clean out Kaltors place to see what would happen.

Kaltor dropped Brilliant Auto-loading Orc Expeller and Pressure Enhanced Slashproof Combat Suit.

When opening all the chests I got 2 more Expellers and 1 more Pressure Suit.

A total of 5 artifacts, 3x of one and 2x of another.

It isn't a bug! Do you expect his stocks to have only one of each item?
