Stoneskin II

[Uielyave]

Not really. SSII lasts 30 minutes and stacks with succor.

That 30 minute marker doesn't mean much of anything. Stoneskin II is merely for beginning battle application. After that, it can not be used in combat. We have to use Stoneskin I after that. Half the time I don't even get a chance to cast Stoneskin II as far as I've seen, aside from when i first enter a dungeon or the first few seconds before boss encounter. Stoneskin II is just for a slightly quicker means of applying stoneskin TO START. After that, you can't do much with it.

Just because it lasts for 30 minutes, doesn't mean it will stay there for 30 minutes.
