according to the official iRO database and the divine-pride both Stefan.J.E.Wolf and bijou are big size, undead race and undead property 4,and as such should receive + 100% holy and fire damage, but this does not happen,
below has the link to the database.

below follows a SS from my ranger, in both cases I use the same items and buffs and the damage on stefan gets far below the damage on the bijou.
apparently the stefan is with property undead 1, so I wonder if this is intentional or is it some bug.
