Ok, so I got most of the effects/attributes for the masks, here they are:

Claw Mask: Default mask which will balance between attacking, gathering, and support to the hunter leaning a bit more towards attacking than the other two.

Fake Melynx: Throws Felvine bombs that will sometimes make the monster drop shinys, will a low chance of being a gem/jewel.

Rathalos: When pinged the wearer will 'Roar' acting as a sonic bomb, main attacks will be melee but when enraged it will shoot fireballs like Rathalos/ian, if the hunter is hit, it will be sent flying similar to when hit by hammer's super pound.

Gagua: The wearer will be less likely to attack, but when scarred/hit it will flea the area leaving an item behind, the item left will variate depending on the 'Mask Mastery' level, but the most common item/shiny left behind will be First Aid and/or Herb

Golden (Your best face) Will block any incoming attack from either monsters or hunter, when enraged it will go berserk and attack the monster ignoring it's health, if the wearer stays in berserk mode for too long without taking damage it will 'Burst' causing his health to drop to zero.

Negation Mask: It can remove status effects given by Altaroth, Bnahabara, and/or Deviljho (Defense down) when pinged as well as elemental blight, the wearer will be very likely to not attack but when enraged will shoot small thunder-balls that act like Jinouga's lightning summon.

Excavation mask (Looks like dung!) This mask's special attribute is to throw dung bombs to monsters if the hunter is being pinned down by it (Rathalos and sub-species, Rathian and sub-species, Deviljho, Jinouga, Dark Jinouga, Gigginox, Gigginox Sub.), also, it will 'Dung' one monster if there are two large monsters in the same area, the recovery speed for the wearer is slow, so using 'Guard UP' and/or 'Speedy Recovery is recomended.

Whetstone mask: Like the name says, it adds the 'Whetstone mask" item to your useable items list, so, even if you don't have Whetstones, you can use the mask wearer to sharpen your weapon, It cannot be used under water, and it has a recovery time before you can use again that is reduced based on the mastery level.

Fake Frog: Same as the Whetstone and Double BBQ Spit, this adds the 'Frog' to the usable items, so you can use it as fishing bait that works the same as a regular Frog, if you set up a trap before you start fishing, when pulling a large monster out (Gobul, Plesioth, Green Plesioth) it will go directly into the trap if whitin reach, also, when enraged, it will make different face expressions.

I'll get the rest of the effects/attributes once I get some more tickets for the Pirate J mask
