In true RPG fashion,Ghost of Tsushimapromises its players more than their fair share of upgradable pieces of gear. These include Jin’s armor sets, katana and tanto, two types of bows, and various projectile weapons.
All of these items can only be upgraded and enhanced if Jin has the necessary supplies and upgrade materials for them. And while the game does throw plenty of these materials at players at every turn, it will still not be enough to upgrade every single item in the gamebefore entering New Game Plus. This is by design. The developers want players to reinvest their time into the game in NG+. But for players who don’t want to do that or simply want to 100% the game faster, there are ways to make the grind take less time.

Bandit Camp Exploit - Infinite Supplies Farm
Directly west ofthe Golden Templein Act 1, roughly 230m away, is a large house that has been overtaken by the Mongols. The house lies directly between the Golden Temple and the river separating the next prefecture. There is an infinitely renewable source of Linen here that can be converted into Supplies. Here’s how to get it.
Each time you loot the 2 Linens sitting on the shelves and restart the game, the two Linens are added to the inventory and two more spawn on the shelf again in an infinite loop.

Gather as much Linen as you can carry andfast-travel to a Trapperto sell them for 15 supplieseach. Gathering 100 Linen roughly takes about five minutes, which means that players can get 1500 Supplies every five minutes.
The limit to how much Linen players can carry at one time is 500, which means players will need to spend about 25-30 minutes to complete a single run that nets exactly7500 supplies.

And since this method is repeatable, there is no limit to how many supplies can be obtained in this way.
Equipping theCharm of Inariincreases the amount of supplies, predator hides, bamboo, and yew wood players get every time they loot them. It is a great way to passively increase your supplies during regular gameplay.
