Orc Berserkers fight to the death and use close combat to kill their enemies, they will also push/kill other creatures to get to you.
Field Notes:
These are dangerous creatures, it is better to fight one than trying to escape because they can run really fast. Warning: Most players under level 20 will die if they meet one.
Stealth Ring can be a life saver when coming across these creatures at low levels. With all vocations these can be handled easily with care.
Knights, recommended skills: at least 60/60 with decent equipment and should be prepared to use Health Potions.
Paladins and Mages should consider using Mana shield or Invisible. However, at level 25+ with a decent magic level it is not hard to just use earth attacks and Intense Healing for this creature, but if they do an exceptionally big hit you can always use health/mana potions, Halberds make it easy to profit. But be careful with invisibility, as Orc Leaders, Orc Warlords and Orc Shamans can still see you. If you find them together with Orc Shamans, kill the shamans first so the snakes don't break your shielding. It's a good summon for mages, however healing runes may be recommended, since they lose health easily.
