Get the summoning, it'll help you alot as summoning is like a shortcut for alot of stuff. BoBs, stat raisers, etc Make sure the familiars dont train defence.
As you can see my account is maxed pure and i ahve 57 summoning and 82 rc atm but i am not bottin as they've started to give out rollbacks to Rcers. and It is worth it 100% I have never regret the 57 summoning.
i have 97 rc on my main and to be honest...the good times are over for rce
to many nature bots.. it isnt worth it anymore to get 57 summon for 300k/h
now the best way to get money from rc is death runes around 500-600k/h
