Please help

It removes the lowest level mod, not the lowest tier. Check https://poe2db.tw/us/Modifiers to see the level of each mod.

I’m not an expert but it gets more complicated than that. Mods all have ‘levels’ that you can’t see, based on the item level. Tier 1 of something on a low level item is going to be different than tier 1 on a high level item. Your omen is removing the mod with the lowest level. So unfortunately in this case, the T1 +2 melee skills is the lowest ‘level’ mod here, even though it’s tier 1 and arguably the best mod on the item. This is a shitty explanation but kind of what’s happening, someone else can explain it better than me.

Basically tier 1 +skills is a low level mod. Tier 3 cold resistance is a higher level mod. Omen removes lowest. Games annoying and doesn’t show you these behind the scenes levels.

It’s lowest itsm level of the mod (each mod has a minimum item level they can appear at), not lowest tier. +2 melee skills must be lower ilvl than T2 cold damage. Annoyingly there’s no determine these things without consulting the wiki.

Oh lol im a moron thought it was tier smh

ngl it's dumb that it's based on something not visible in game...
