Here's one I did'nt see mentioned:

The tooltip for the Rune Chain spell reports an incorrect damage value when enhanced with a units runes.
I click the spell, then a unit with enough runes to get the most out of the spell, then highlight an enemy and the tooltip says it will deal 610 damage, but when cast it only deals 462 damage. (I've cast it on many unit types and its not a resistance thing).

Also, the tooltip will report a higher damage value if the unit has more runes available. Casting it off my Soothsayer will say 759 damage, and this can be further increased by giving him more runes with Runic Word spell, the damge inflicted will still be 462 though.

Edit: One more I just found. The item 'Block of Honey' degrades even when not equipped.
