This perk actually lowers the difficulty of any lock Henry attempts to open, which allows players to try and lockpick the very hardest locks in Kingdom Come: Deliverance from very early on in the game.
Mule (you can carry 15 pounds more): this perk will allow players to gather more loot before having to sell it off and is also very important to equip heavier armor which there is plenty of later in the game.These Kingdom Come perks are widely applicable and are the ones players should get first.
