Fifty, plus the hundred gold advance.<br/><br/>18.75 on the heavy crossbow.  I'd recommend light for the reload time, but I suppose you're not likely to use more than one shot before switching to melee.<br/><br/>The only real alchemical goody I can make right now is acid, at 3.75 gold a pop.<br/><br/>Banded mail is, as stated, 93.75 gold.<br/><br/>The mail and crossbow together would be 112.5 gold, which is affordable considering the advance, with 37.5 gold remaining.  Toss in two vials of acid, and the total price goes to 120g, with 30g left.<br/><br/>And special materials are too expensive for now anyways.<br/><br/>Edit: And both potions and dogs are beyond my abilities.  I get potions at level two.
