Prioritize Your Needs
Rise of the Tomb Raider wastes no time in providing you a lot of different options for you to spend your precious resources that you have hunted and gathered. Don’t go spending them on the first thing you happen to see. Take the time to read each available upgrade node and decide if it’s even something that you’re going to take advantage of.
Resources can be burned through VERY quickly if you try to upgrade every skill early on. Only upgrade skills that you know you’re going to actually use, unless you literally are at capacity for your resources. For example, there’s no point in getting the Stock-Mounted Shell Holder if you don’t use shotguns very often. On the flip side, there are equipment upgrades that are useful no matter what. For example, the Satchel, which increases your resource storage capacity. It’s great for those that want to save their resources without worrying about capping them often.
