The steward of Whiterun gave me the smallest amount of gold EVER for retrieving his daughter's sword.
Spoiler Assassinating the Emperor nets you 20,000 gold...19,000 of which you must spend to upgrade your keep

"I've killed the giant at Whatever Crossing."
"Thank you! You've done us a great service! Here, have a hundred gold, ya putz."
Yep, this. I'd love to make a living hunting bounties, but I can make ten times as much gold just through trading stock in the markets without risking my livelihood. Hell, I can make that 100 gold just beating some poor bloke up in a bar fight.
Agreed; worst shout in the game IMO. I'd say that Dismay is useless, too, but it's just a matter of playstyle. If you use Illusion or a Nord, you obviously don't need the shout, just the same way a mage doesn't need Elemental Fury.
For that matter, why aren't there any shouts that work particularly well with mages that don't really benefit non-mages?
Oh man, no kidding. +30 to each of the 3 base attributes? Casters don't give a rip about 30 to stam, and most non-mages usually don't give a rip about +30 to magicka... so yeah. You only get 60 points towards two stats you may care about. So, you barely beat a +50 necklace to one stat, and there's no way I'm going to wear Gualder's when I can instead wear a necklace that greatly boosts archery or melee damage, instead. Or magicka regen. Or whathaveyou. If it had given +50 to each attribute, it would have been worthy. Or at least +40....
Srsly.
Yes, it's of great benefit to, say, a battlemage who uses all three stats. But you are likely to find a necklace with a high enough buff in one attribute that it outclasses the Gauldur Amulet, and with moderate Enchanting, make one yourself. If you're a master enchanter, then you could easily make an amulet with double the power of the Gauldur Amulet spread across two attributes.
Still, I wouldn't say it's the most useless.
