This is a bodyguard that was not originally made of Boulder material.
It's fully upgraded. (Except the upgrades from tools)
Boulder was placed on it. Yet only the Evade and Weight have changed
7 base armor + 8 UL = 15
0 base magic armor + 5 UL = 5

Boulder lists itself as giving +7 of both Armor and Magic Armor.
It's currently not applying to this one, for whatever reason. Relogging and Re-equipping it didn't fix it.
It should be statistically impossible to have less than 7 on magic armor after putting Boulder on it, unless you had grimey, which it doesn't

Wonder if this has anything to do with the fact that we can't get boulder from breaking items down. . ? Strange.
