Gyfin temple is an end game grind zone. Gyfin mobs used to be grinded for xp but now with Mirumock being introduced into the game it has made Gyfin Temple not needed. Gyfin Temple requires you to be in a group to grind here the mobs hit really hard so you will need at least 320 plus dp to grind here. If you need money definetly do not waste your time here as it it not worth the time invested anymore. Try Stars End as the money there is much better.
