Best thing I've been able to do as a blood mage, is make sure you get the rested Status in Dragonstooth from the Inn Guy, then head back to the port and get the Gentle Warmth and Arcane Blessing from the hooded woman and the Wizard respectively. All of them together should let you deal with a few of the enemies whilst only using Mana when absolutely needed, just need to get a weapon from the town of beginnings as soon as possible.
