*Use Gog mats to enhance Artian weapons(damage?) and a have them gain a random skill.
*Some more event quests that grant Artian materials are becoming permanent
*Once you reach HR100 you can limit break armor to upgrade them more, it sounds like lower rarity armor like 5 and 6 will gain more slots.
*Armor sphere are going to become more common overall and you will get more Heavy Spheres from your bounties
*some event quests that give lots of armor spheres will become permanent also.
* 9 star Rathalos can appear randomly in the field and you can save it as an investigation
