- Insane - start with the BLUDTUPOWA glyph
- Power-hungry - mana potions 100% effective, reduce health by 6 per level
- Sanguine - restore 15% max health from blood pools
The Blood Mage's free glyph isn't as useful as the glyphs from the other classes. If you're low level it will net you one or two extra spells, but the higher your level goes, the less helpful it will get (there is some balance missing there) so you might as well can get rid of it. The way to go with the Bloodmage is to get as many mana potions as possible and leave the blood pools from killed monsters untouched as long as possible. The bosses can be taken on using fireballs, HALPMEH, CYDSTEPP and/or poison (whatever works best) and with the help of bloodpool regeneration. You'll be able to cast a lot due to the mana potions' 100% regeneration, but the health loss from using a potion makes it more difficult to use several in a row, as you'll need to save up blood pools and/or health potions. Note that you won't be allowed to drink a mana potion if you do not have sufficient health.
Race & Deity Choices
Gnome or Elf are your ways to go here. As a Gnome you'll have a lot of Mana Potions and therefore a lot of mana. As an Elf you'll have more Mana overall but less Potions for regeneration. The Elf, due to having more overall mana, definitely has the advantage when trying to take on monsters without using potions. On the other hand, the Gnome will miss individual potions less, and can take on monsters that are even higher level than the Elf can without setting himself back too far against the boss. Against the boss, a Gnome who has many potions saved up will have more mana overall (by 25, at 5 glyphs converted), however, the Elf will have to pay less health to use up all his mana, and will be able to more effectively melee the boss in conjunction with any magical assault. Note that if the dungeon spawns with shops or Deities that allow for expanding maximum mana (such Mystera Annur), it favors the Gnome, while spawns and midfight leveling strategies that allow for more mana refills benefit the Elf more.
Mystera Annur should be your preferred Deity, and makes BLUDTUPOWA look significantly more useful, as you don't need to regenerate health as much if you aren't attacking enemies directly. If that one's not available you can still go with The Pactmaker, Jehora Jeheyu (if you won't depend on CYDSTEPP) or Tikki Tooki.
Level up by killing Gorgons and go only for Serpents and Nagas if you can kill them without getting weakened or poisoned (except you'll get a level up or use HALPMEH). Try to not use any Mana Potions until you're able to take on the bosses.
If you're around level 7 start attacking Medusa. Immunity to Death Gaze is helpful but not necessary. Just make sure to keep your Health up with bloodpools, potions and level up. Make sure to keep enough potions for the Nidhogg, who can be outlastet afterwards.
