I don't know why, but it seems that some types of damage in fashion have some kind of limit. What, in fact, is the matter - I pumped my character using the Level+ mod. and at one point, all the weapons from The Stars Above that had a special type of damage (for example, Celestial) began to have 0 damage. the rest of the weapons with the usual types of damage (melee/ranged/summon/magic) did not have these problems. This happens when weapons have very large damage values, somewhere in the million - hundred million.
