Warfan, metcurisl, maul, etc these weapons automatically shoud have a +1 atk unseen by stats. This wad done back in vep 2.1 similiar to items that give bonuses due to material. I am not certain if this has changed in later cep. But in my hay day scripting if you look at the items blue print it gives a +1 atk this was an issue when players who possessed +5 atk items were rolling +6. But that was a long time ago in old cep less the items used by the team is just the skin and not the cep blue printes item.
