Maybe you fed it a dozen different additional stats, it will only give you 4 to choose from. These 4 choices will be based on the additional stats of the items you fed to the weapon to upgrade.Once you've filled the experience bar you gain a level and you get up to 4 different choices: they either add a new stat to the weapon OR slightly increase a stat that was already on it.The amount of weapon experience you get is based on the rarity of the item.
Try Murder of Crows (for ranged attacks, the gun is weak) and Harvest (for an area attack, you get crowded by lot of weak enemies fairly often).
The level cap is raised from 22 and 30 and this new cap opens more of the Crucible (challenge arena). Quests and collectibles are reset (but you keep their rewards). You keep your level, inventory and skills. After you complete the game you can use your save for New Game+.Unlocking the Abyssal Armor bestows some pretty powerful abilities to add to that impressive arsenal but it sucks you have to buy the DLC to even get it as an option. The strongest armor to appear in the first two games, it takes until this very DLC to appear for Fury. Upon defeating this behemoth of an enemy you will finally be graced with the beloved Abyssal Armor. This all eventually culminates in one truly epic boss battle to put your skills to the test. This opens your arsenal up from five to nine new weapons, and I much prefer these new brutal combat options as opposed to the stock ones in the base game. The spear made of lightning is replace with a double bladed staff, the hammer with a large axe, and the broadsword with dual scythes not unlike the ones Fury’s brother Death would wield in the previous game. What is essentially flaming nunchuks, for example, are now burning claws.
These are not merely reskins, but will have greatly different abilities, attack speeds, and reach distances. Of course what good is a challenge without rewards? You’ll encounter boss fights against formidable golems that – when defeated – will drop an all new weapon for their respective Hollow.
