Grease

I just want to confirm that grease does not work on noremove weapons and irongripped weapons? The echo I saw on an Irongripped weapon didn't reassure me that it was impossible for the ap to not drop the weapon. "Despite the grease on you, you manage to hold onto a Wicked Battleaxe." This sounds like the same echo when a person manages to hold onto a normal weapon during a round of combat. Maybe give a different echo when this happens to irongripped weapons. eg. The grease is powerless against your unbreakable grip on a Wicked Battleaxe. or somethinng to that effect? Just something I noticed
