Skylanders Spyro's Adventure soul gem locations guide

Gem #4: Stormy Stronghold

Unlocks: Warnado’s “Thick Shelled” Ability

Toward the end of the level, you’ll find this Soul Gem behind bars. Remember this location.

Move forward until you come to this slope. Stand on the switch on the right to lower the bars guarding the Soul Gem.

You’ll have twenty-seven seconds to get to the Soul Gem before the bars rise, so hurry back! Use a quick character like Spyro to get there in time.
