Right, here's my long-term plan:
Whilst I'm ranging raise kittens into cats and trade with 'Civilan's for 100 deaths ea.
After I get 70 ranging, then start making the 3.5k ess into 7k fires to get 50 runecraft. Whilst I'm runecrafting I can of course carry on raising kittens. I will then have enough runes for 1k Fire Blasts. =)
