Since rune caster fits into a warlock build (both based on linker or cryo kino), making rune of justice work with mastema’s holy damage amplification could improve its viability as a grind time burst DPS, where as its current role is just a mission boss killer.
it used to deal holy damage, but I think they changed it. I removed my Rune of Justice for Rune of Protection recently with a skill potion (this skill is OP on GvG), so I’m no longer able to test this.
I’ve been a rune caster before merge patch and I vaguely remember that too… But back if memory serves, it didn’t work properly back then either.
I used to have Holy on tooltips, but now just says is magic, perhaps they removed the attribute to lock wizards out of holy property attack since very few things can resist it.
