How to unlock the The Stones’ Power achievement in Dungeons 3 - Definitive Guide
This is done in the "The Gehenna Stones" level. In this level, you're required to use Thalya to convert Gehenna Stones. Once you convert one Gehenna Stone, you begin to accumulate Stone magic, which allows you to cast a powerful lightning spell. To access this spell, press to access the top right icons, then press to highlight the spell, hit to select it, then hit again on any group of Heroes. This spell will kill any Hero outright.
As you go about doing the level, make sure to use the spell once it's fully charged to kill any Hero in sight. There are more than 15 Heroes so you won't miss out on the trophy as long as you remember to use the spell. The spell works on any Hero that is visible. Even if you have killed all the available Heroes and forgot to use your spell, you can wait for the endlessly spawning dungeon-invading Heroes although you'll have to kill them on the surface.
