Dragonstone/1.03

High Elf
Excluding building upgrades, the Dragonstone is the final building that the High Elves can build, and one that may not even be needed to be built. This smallish building only improves the Hero's spellcasting chance and produces Wyverns. Although Wyverns are decent units by nature, they offer very little to the High Elven race and their removal will have very little consequence to the the High Elves, if any at all. If your Hero has no spellcasting capabilities, or already has a 100% chance to cast spells, then the Meditations skills are completely useless and need not be researched, which then should prompt the question as to whether you need to build the Dragonstone.
