how to lvl def without hp?

it is possible. Books/Genie Lamps/Penguin Points. My Skiller friend had 16 Combat with like 40+ Defence He had 10 HP

 

Ok here: I didnt know for myself so I went to that runescape wiki thing and found out: http://runescape.wikia.com/wiki/Penguin_point

 

Pest Control and Genie lamps work

Its hard to make 10hp pures because if you want to stay 10hp.
It'd also take skilling to get the lamps and so.

 

Just get a bunch of food and use as much prayer as possible this will help you I was in this situation once.

 

Lumbridge Dummies, theres a script on rsbot that attacks them and you get no hitpoints xp for it

 

Oh ya i remember that now.
