DWARF URDVAERG ABILITIES

Unless I got some google search terms wrong these do t seem to be a thing...

I could brew up some kind of stat block for a dwarf-asimaar type thing (I've been considering doing some more varied half-races) but you'll need the boy fluff as I can't seem to find anything on these guys.

Actually all that depends on what edition you want, I'm only brewing in 5e at the moment.

I don't have my MMV on me so the only semi divine template I have on hand is lolth-touched though that's a good place to start.

Abilities: Increase from the base creature as follows: Str +6, Con +6.
Skills: A Lolth-touched creature gains a +4 racial bonus on Hide and Move Silently checks.
Special Qualities: A Lolth-touched creature has all the special qualities of the base creature, plus the following spe- cial quality.
Fearless (Ex): Lolth-touched creatures have immunity to all fear effects.
Level Adjustment: Same as the base creature +1.

This seems like a decent starting point only the skills irk me, so I would adjust them to be

Skills: A Udvaerge gains a +4 racial bonus on all Crafting and Proffesion checks related to stone working, mining, smithing and brewing.

Now just slap this template onto your favourite brand of dwarf and we're halfway there.

The master of all weapons and rune magics clearly need to come from class levels; I would go with...
4 levels of fighter
1 level dip into wizard
5 levels of Runesmith (out of races of stone)
10 levels of Runecaster (out of Faerun campaign setting)
(For an epic desciple Id fill out the remaining levels with fighter)

That said at this stage in building a caster character with no idea what level your aiming at, and no real desire to jump back into the cheese ridden mess that is 3.5 character creation.

Hope the tips help, good luck!
