To be a fighter, you stay at a level where there are lots of prey (7-20 usually). You fight regularly and give most if not all of your experience to your clan to stop leveling out of reach of easy targets. By training every day and ‘level sitting’ you become stronger than most around you and can fight to increase your clans respect and, by taking part in wars, battle karma. To increase your stats you use the blood pond, vials of max +3 hp and gym trains.
