You can recieve advanced training by going to any journeyman blunt trainer, and going to talk to Irene Metrick for training. She will say you need to kill 50 people. Go back, and she will train you.
Blunt determines how skilled with a blunt weapon you are are. Things like maces, axes, warhammers, and clubs fall into this category. The higher the skill level, the more damage. Blunt is governed by Strength and is a Combat skill.

- While going through the Main Quest, Fighters Guild and Mages Guild your blunt skill will go up naturally if using a blunt weapon, as you'll many enemies to fight.
- Putting the difficulty level on slightly harder will give you more training as enemies will have to take more hits before they die.
- Alternatively, you could use a weaker weapon. Get rid of that Daedric battleaxe and use a steel one instead, and you'll have to hit enemies alot more before you kill them.
- Train your Conjuration skill as well and summon monsters in a location away from city guards(i.e your own house, out in the wild) and kill them, over and over. Watch out though, when you hit your summoned monster three times they'll turn on you so be prepared.
