Olafur's "Harumph" skill is an Earth attack with 50 base power. It has the effect of giving yourself Immunity to Freeze, Possession, and Daze. This part of the skill works as intended. However it's suppose to also randomly give these immunities to allies. For example 1 monster could get immunity to Freeze, and Possession, but the other just Immunity to Daze. This part doesn't work correctly at all. From testing this skill over 20 times it just gives allies Daze immunity, and that's it. I really wish it worked as intended, and I've been reporting it since getting him from the Winter Maze he was from, but end up getting Ignored from support. With my post also being drowned in the official bug report post. I decided it was best to make my own post on it to get the word to someone in power.
Honestly I think it be best just to change it into the skill just giving everyone Immunity to Freeze, Possession, and Daze. Instead of this random factor that may never be-able to be programed right. However that's just my oppinion.
