How can a 15 ft. Frost Giant(level 9) have a Stealth of +17 (and +21 in snow).
With a level of 9 and Dex mod of +0 they would have a Legendary (Lvl+8) Stealth if they were bound by the same rules as a PC.
Frost Giant Stealth technology has evolved a lot since Pathfinder 1 (Stealth +2 (+6 in snow))
And why are dragons harder to spot the bigger they are?
A young blue dragon (Large) has Stealth +15 while an Ancient Blue dragon (Huge) has Stealth +28.
Oh look what a Huge Blue rock I found!
How would you modify these ridiculous Stealth modifiers in your game?
