I suggest for non members: lesser demons as you can get good drops while getting good exp.
Members: pest control is a great way of getting exp, and one of my favs to train defence on is cyclops in warriors guild. I have stopped that though and now into pest control. You should check it out.
The best and most efficient way to train defense on runescape member's worlds is to train on rock crabs. Rock crabs have 500HP, low defense, and a maximum hit of 15, they also drop clue scrolls.
A good way to train combat in Runescape is to go to Soul wars. whats the best thing if im nonmembers
The easiest way is with a mystical lamp.
Fighting. Actually it's the only way.
try killing experiments.
Pest Control.
depends if you have good armor, weapon and food you should kill moss or hill giants
Probably training on Fir Giants at baxtorian falls.
Get a weak weapon and fight barbarians at the barbarian village.
Karambja Volcano, Lesser Demons.
simply chose block in the sword option and kill as many things u can. or if u are members talk to boldman2000 near varrock and give him money he will increase ur money + defence lvl THE BEST WAY TO INCREASE YOUR DEFENCE IS TO GO TO THE STRONGHOLD OF SECURITY
here's the best way to get a high level runescape acount. make an acount train all skills to 70 then train bandits till you have 99 in every combat skill. now you have a high level runescape acount :)
