RuneScape - If you're unable to find the royal crossbow
If you're unable to find the royal crossbow, think about OSRS gold a think about getting one like the Armadyl. Always utilize 2H or dual weaponry for slayer tasks. Go with the highest tier weapon that you have. If you got a lv 80 ranged wep and an 80 melee weapon as the top weapons, use the weapon which your monster is the weakest (according to combat triangle).
