Ok so im 72 range now and i want 80 where should i train?? I dont just want ... fire giants i want to know some other good areas to train my range effectivly :D

The more you hit and the more often you hit the more EXP you will get, so find the best monster with the most HP and the monster you can hit the most often and you will have your place to train.

Maybe you should try the Ogre Dungeon and bring 15 law runes just in case you want lvl3 clue or rune full helmet. Telegrab these good drops.

u mean range the greaters in there?

Yes
