Beowulf:

Display: '&8Beowulf'
Health: 50
Damage: 8
Skills:
- message{cooldown=20;m="<mob.name><&co> You seem to have angered the bewoulf..."} @PlayersInRadius{r=40} ~onCombat >0 0.2
- message{m="<mob.name><&co> RAGHGHHR!"} @PlayersInRadius{r=40} ~onPlayerKill >0 1
AIGoalSelectors:
- 0 clear
- 1 meleeattack
-...
