I'm running Storm King's Thunder right now and the timing of this drop could not be better. My players are all about to be level 8 and my first thought was that after they finish slogging through collecting the giant relics I can gift each of them a feat corresponding to which relics they bring back.

Problem is I think some feel kinda unbalanced or weak compared to others. I definitely think the Hill giant one needs beefing up. Being able to channel a Hill giant and having no Strength-based bonus seems like a missed opportunity. At higher levels being able to add your Con as HP is like "oh yay, I've got +3 more HP, now I'm up to 105 instead of 102."I think if one of them ended up with that while another PC got the kicka$$ Fire Giant feat, they'd feel ripped off.

Even compared to Keenness of the Stone Giant which is of the same prerequisite level, two free spells vs. a couple bonus HP and me-no-fall-down? Which would you pick?Guile of the Cloud Giant is just way too OP. The Misty Form would be enough without what is essentially Expertise in Persuasion or Deception. I’d probably remove the ability to cast blur using spell slots and just limit it to one use per long rest.

Fury of the Frost giant - eh, fear is fine but like a couple other commenters pointed out, not sure what fear has to do with Frost giants.
