You realise that firemaking cost me 30k to get to level 60 using top wood? Getting to 99 takes around 60 times longer than getting to 60, so it costs around... 3.6 mil. I got 60 firemaking in around 2 hours. Youtube videos for firemaking to find fast ways to train this. This is the skill you want if you take ages leveling.
On my pure I got to level 60 by accident. The highest I've ever got a level is 70, and that is on my main. Now my pure is like leve 40 combat, everything at level 1, and a random 60+ firemaking...
