Tiers

There are three Tiers of Upgrades for each of the different Skills (Survivor Upgrades, Hunter Upgrades, Brawler Upgrades) in Rise of the Tomb Raider. The higher Tiers can only be unlocked after a certain amount of lower tier skills have been unlocked: Eight for the second tier, 19 for the third. Note that for some of the higher tier skills other specific lower tier skills must be unlocked first; e.g. to unlock Triple Shot from the second tier, one needs to unlock Double Shot from the second tier first.
