I'm 58 combat with 40 defence. I recently got 44 RC and a mounted glory + home tele, and I've been using it to grind nature runes via the abyss. I'm taking a lot of damage, though, and have to eat a lobster or so every single trip back which really slows down my xp/hr and gp/hr. Is there any efficient way to do this at a lower level, or do I have to deal with it?
