Skills in Gloria Victis are leveled through use. The more you use a specific weapon type, armor type, or crafting profession, the more proficient you become. This unlocks new abilities, passive bonuses, and allows you to equip higher-tier gear. Key skill categories include:

- Weapon Masteries: Swords, Axes, Maces, Spears, Bows, Crossbows, Daggers. Each mastery unlocks specific weapon abilities and damage bonuses.
- Armor Masteries: Heavy Armor, Medium Armor, Light Armor. Higher mastery reduces movement penalties and increases defensive stats.
- Combat Skills: Blocking, Dodging, Stamina Management. These improve your general combat effectiveness.
- Crafting Professions: Blacksmithing, Leatherworking, Carpentry, Alchemy, Cooking. Each profession has its own skill tree.
- Gathering Skills: Woodcutting, Mining, Herbalism, Skinning. Improve yield and speed.
Focus on leveling skills relevant to your chosen build. For instance, a heavy warrior will prioritize Heavy Armor, Sword/Axe mastery, and Blocking. You gain skill points as you level up, which can be spent in the skill trees to unlock specific abilities and passive bonuses.
