So, I thought of a possible weapon upgrade system, different from the well of course. This would be used to upgrade current end game weapons (and maybe even armor?) if possible.
-There could be a new boss/npc that would drop 3 different crystals to upgrade the weapons. Tier 1 would give a 25% success chance, Tier 2 would be a 45% chance, Tier 3 would be a 90% chance at success, and the weapons perhaps could have a boost up to +10, the boost giving an increase in accuracy and damage, the biggest jump/increase being at +8-+10. I'm thinking that at a +10 the weapons could do a max of maybe a +30% damage/accuracy boost.
-If anyone likes the gear upgrade idea (Armors), the same boost could apply, perhaps for example, it would be a boost not only with defence, but also an additional damage buff for wearing an entire upgraded armor set [E.G Full Celestial +10 would give an additional 20-30% damage buff]
Oh, and to top it all off, these upgrades would be account bound, meaning [E.G if you sold your SOV XI +10, but bought another one later on down the line, you would still have your +10 upgrades. The person purchasing your SOV XI would get a raw XI, 0 upgrades, until they apply their own crystals to it to have a damage/accuracy buff to it, or unless they had one previously and had upgrades they've done]
Please feel free to leave your feedback Hope it wasn't too confusing xD. Thanks everyone!
