Quick combat levels in f2p?

[Loyal 2 da game]

I'm currently leveling my friends account, legitimately. He's free 2 play, lvl 70, 62 str, 58 att, 50 def, and he has full rune, etc.

I just need to get his attack to 60, and str to 65.

I'm currently doing minotaurs, but are there any quicker alternatives?

Try flesh crawlers. They're found on the second level. They auto-attack so you can afk a bit.

Alright thanks. Also didn't mean to post this in cheating, my bad.
