all racial abilities are independent of levels cause they have a relative bonus except the dunmer bonus...does it get stronger with levels? cause otherwise i imagine it will get useless after a few levels?

You'd be surprised, I'm at level 8 and almost rely on that and flame (compounded with a steel sword) to do most of my damage.

Actually most greater powers don't directly scale except for Orcs. Altmer and Argonian scale indirectly if you happen to add magicka and HP respectively.

sure they do scale, they are all relative - 10 fold something for 60 seconds is as good for 100 something or for 500 something...? but an absoulte number stays an absolute number...and level 8 isnt really that far progressed

I had a thread about this too. But it was more about how a regular spell,Flame Cloak, does the same thing as this trait. It's like a repeat of the ancestor ghost/summon ghost deal from OB.

thats actually the reason why im thinking about going for redguard rather then dunmer...the redguard ability seems to have a lot of usability
