Well, after 90 hp, 99 wc, 99 fish, I was thinking of 90 mage...
Anyway, I've planned it all out. Mage longs will only cost me 1.5m for lev 90.
I think I will only be able to afford loads of 2.5k.
If I alch in barrows, I won't get any randoms, and might get a lagged out reward.
Full infinity (Est 6.4)
Mage book (Est 2.4)
Mystic lava staff (got)
Magic ammy (t) (95k)
So about 9m total costs for equip.
That leaves 10m or so for buying stuff to alch.
