Hunter

Fierce creatures that attack anyone who approaches them. Often mistaken on PVP worlds as a PKer by newbies. They are very dangerous for low level players. They can shoot you from off-screen.

A hunter attacks from a distance. A hunter will retreat at 10 (6.67%, red) health.

Knights should approach them quickly before they shoot more Arrows. A good strategy for knights would be to run towards them in full defense and once you are near them, attack with full offense. Another strategy is to duck behind a corner of a house and force the hunter to walk closer to you. Because of the hunter's low defense a knight can kill them easily.
Paladins should not fight these creatures unless they have a Stealth Ring, shield or high enough skills to kill them in 1 or 2 shots, and if you're planning to kill it without spells or runes, make sure to have a good healing spell, rune or potion ready in case of a high hit. A distance level of around 50 is recommended to kill them easily.
Mages should use Invisible or if they are hunting them they should summon monks. Overall, stay away from these unless you have to get through them to get to where you want to hunt (e.g. Heroes) or if you need to get a pair of Sniper Gloves. They usually aren't worth the trouble.
