Couldn't think of a better name, but item merging, at least in this case, is being wonky.
Sorry if this is known behavior, or accepted shifter glitchiness. But I couldn't figure out why and it caught my eye.

Unmerged item on top, no normal enchantment, +2 vs undead.
Merged weapon in the middle, minotaur greataxe, normally +1, +2 vs undead.
Stat sheet on the bottom, where I am getting a *lesser* attack again undead.

+18/+13 is the normal AB I get, shifting without any weapon at all.
The game uses the highest bonus, so I'm not getting a lower attack vs undead, but the item property isn't working either.

A couple of things I can think...

1.It may calculate +2 enchant v. Undead as higher than +1d4 damage v. undead because you get the AB and damage bonus.

2. The +AB v. Undead would not show up on your Character Sheet at all, it would only show in the combat log.

I'm not sure if that answers you issues?

What's your normal strength before you shift into Minotaur? And your current levels in druid/shifter?

1. It's the +2 vs Undead that isn't applying. Damage specifics are hard to see, with it all being physical though, so I really don't know what was applying or not there.

2. Assuming character sheet glitches first, that's what I looked for. The combat log was displaying to me as +18 AB, which is the calculation with the +1 instead of the +2. It should have been +19 AB in the combat log.

Normal str is 10 unshifted, 20 in minotaur. First picture was at druid/shifter levels 5/4.

Tested again just now with a different weapon (+2 vs humans), and different shapes for the same result. Druid/shifter levels 5/7.

Out of curiosity I tried to mimic the behavior without shifting, putting a +1 enhancement on the weapon with +2 vs humans. It appears on the character sheet just as it should, so it's definitely something to do with how things merge.

This is correct. The character sheet lies, don't trust it. The combat log, on the other hand, is always reliable - it's 18 AB because you have -1 AB as a minotaur. They're large creature size.
