Just rolled a Breton 'Witchhunter', I think he has staying power. Focus on Archery and Restoration, Smithing, with Conjuration, One Handed and Lockpicking as (very) minor support skills. A sort of 'treasure hunter' Archaeologist, a lovin' for Deep Folk and their tech, was a skilled undead hunter back in High Rock out of necessity, and of all the luck this damn country is full of them!

He just has one query about marksmanship: when he bashes with a bow, does this train the Block skill? And further, does this bashing benefit from 'Deadly Bash' (ie. 5 times more damage from bashing), though he does know that he can't power-bash with them. Is the damage related to base damage of the bow, as with other weapons?

I'm not sure if it levels the Block skill, but it does benefit from Deadly Bash.

Surprising that you would need to power bash with the bow. Bound Bow early on is a crazy powerful tool with the right setup.

I don't use Bound weapons. Besides, Guy's a technology aficionado, only Dwemer will do.
