Tomb Raider (2013) · Progression system
Skill tiers at camps
Skills are learned by spending Skill Points at camps, with three tiers and a stated seven point threshold to unlock the next tier.
How it works
StrategyWiki says each skill costs one point and skills are divided into Rookie, Hardened, and Specialist tiers. Spending seven points unlocks the next tier. WikiRaider describes Skill Points as earned through XP. The passages do not list total skill points, category-specific prerequisites, or whether the threshold applies identically to each category.
