Ascending weapons in Nier Reincarnation increases their level caps (allowing for more Enhancements), improves abilities, and unlocks new abilities. Overall, doing so will make you more powerful and increase your Force number, helping you take on tougher quests, subquests, and events. 

To Ascend a weapon, you’ll need 25,000 Gold and certain Ascension materials. You can perform Ascensions with Pearls and with the same type and level of weapon. Let’s go over Pearl types first.

2-Star weapons require Pearls 3-Star weapons require Natural Pearls 4-Star weapons require Black Pearls

Pearls can be purchased from the Shop with Arena Coins, Bookmarks, Sunset Port Medals, and Automata Medals. Here’s what each one costs for each currency type: 

Pearl 75 Arena Coins 90 Bookmarks 120 Sunset Port Medals 120 Automata Medals Natural Pearl  400 Arena Coins 500 Bookmarks 600 Sunset Port Medals 600 Automata Medals Black Pearl  1,200 Arena Coins 1,500 Bookmarks 1,500 Sunset Port Medals 1,500 Automata Medals

It’s possible that Pearls drop from quests, subquests, or events, but I’ve not yet had one drop as a reward, so I can’t confirm.

You can also use weapons of the same type and level to perform Ascensions. For example, if you have two 4-Star Emil Heads, you can use one to Ascend the other. You’ll still need 25,000 Gold, but since summoning dupe weapons it actually easier than getting some of the resources to buy Pearls, this may be a faster method.

To find your weapons, open the main menu and click on “Enhance.” Then choose “Weapons.” Every weapon in your deck will appear, and those with a red diamond in the upper right-hand corner can be Ascended.

Just as with characters, weapons can be Ascended four times.

And that’s all you need to know about how to Ascend weapons in Nier Reincarnation. Ascension is essential to taking on some of the harder missions and quests in Reincarnation, so be sure to take advantage of the mechanic whenever you can!
