I'm trying to get a lot of limps, I've tried hobogoblins, they drop at a decent rate, but it's kinda slow. Also Hill Giants are way too crowded... I'm f2p by the way... Any ideas on how to get them...?

For f2p i think hobgoblins are your best bet. In members the only thing better than hobgoblins are cockatrices.

Yeah, but hobogoblins don't drop them that often... I guess for f2p you're limited...

Even though the Hill Giants are crowded, most F2Pers leave them on the ground since most F2Pers think they are worthless. Just run around and collect when you can't find a giant to kill.

try doing what berrakus told you

Hill Giants are most likely your best bet.

 

If you're f2p, yeah they're crowded, but just pay attention.

 

If you're a member, its pretty easy to find a free world and have them all to yourself \
