Like if you wear a Crota mask, Hive enemies won't attack you, or at least until they're fired upon or you get too close or after a certain amount of time. Same with the Aksis mask for Fallen, Atheon mask for Vex, Oryx for Taken... The other masks would have more specific perks, like: - The Warden/Variks masks keeps PoE enemies off your back for a while, or the modifiers don't apply to you. - The exotic and legendary engram masks raise the drop rates for those engrams. - Skolas mask wards of fire from Fallen on Venus. - The SIVA mask protects you from SIVA mites and grenades. - The Queen's brother and Petra mask gives bonus Queens Wrath rep on all activities. (because taken bounties aren't enough) - The ghost mask marks materials on all planets. - Cryptarch mask decodes all your engrams in the field. These are just some crazy ideas I had in passing. If they are going to be 0 light helmets, it wouldn't hurt to have a fun little secret perk. What are your thoughts?
