ValhallaMMO features 14 skills natively you can level up. Each skill has a skill tree, populated with perks you can unlock to gain specific bonuses.
Use the arrows to navigate the skill tree, and clicking on a skill icon will center that skill and reveal some others sort of like a scroll bar.
Each skill (except power) has an additional perk that allows you to reset that skill. In exchange you get some permanent stats for that skill and you get your skill points refunded, but also have EXP gain for that skill reduced a bit so your next run will be a bit harder. This also allows for a higher power level since you get to level skills again. This is known as New Game+ (NG)
