In Assassin’s Creed Valhalla, you can upgrade your character’s power level by increasing their gear level and skill points. Here are the steps you can follow to upgrade your power level:
Increase your gear level: Your character’s power level is largely determined by the gear they are wearing. You can increase your gear level by finding and equipping higher-level gear, or by upgrading your existing gear at a blacksmith or a crafting bench.
Increase your skill points: Your character can also gain power by investing skill points into various abilities and perks in the skill tree. You can earn skill points by leveling up, completing quests, and finding certain collectibles in the game world.
Upgrade your settlement: As you progress through the game, you will be able to build and upgrade various structures in your settlement, such as the blacksmith, the armory, and the tattoo parlor. Upgrading these structures will unlock new gear and crafting options, which can help increase your power level.
