Specifically: You're looking to hit level 10 as early as possible so you can one shot the level 9 baddies that spawn whenever you hit the boss. Dracul blood tithe + hunger means you heal a ton of health every time you hit the boss
Also, try to avoid exploring everywhere in the boss subdungeon straight away - more blackspace = more dead level 10 bandits = more bloodpools for when you actually face off against Draugr.
Also, weytwut and pissorf can do endiswalls job well enough. Just remember to always spam them when you have spare mana.
