Experience in Arena is primarily gained by defeating enemies. The more powerful the enemy, the more experience you receive. To level up efficiently, focus on clearing dungeons thoroughly. Don't shy away from random dungeons, as they are excellent for grinding. When you level up, you gain hit points and potentially attribute points. The amount of HP gained is influenced by your Endurance attribute, so a high Endurance is beneficial for survivability. Prioritize increasing your primary attack attribute (Strength for warriors, Intelligence for mages) and Endurance with your level-up points. Remember that some classes gain more HP per level than others.
