Im looking for a monster that i can range from a safe spot u know like blue dragons?only thing is i need a lower monster that i could actually hit for some damage
Buy heaps of lobs / 10k iron arrows, Pile up a bunch of rock crabs, fast as exp.
Experiments would be no good because you can only attack one at a time, for fast range you need to pile up a mass of monsters and attack them = Fast exp.
I would go with karamja scorpions until you hit 47-50 ranged, powerrange hobgoblins at crafting guild until 60 ranged, and than finally, safe spot ankous. Best xp in f2p =D
get an accumulator, then you won't have to worry about your arrows. Then try the fight caves. You lose nothing when you die, so just go in there and you can afk til you die.
