Eanswythe in Heroes 3

Weakness

Casts Weakness with effect increased by 4 for 1-2 level creatures, by 6 for 3-4 level creatures, by 8 for 5-6 level creatures, and by 10 for 7 level creatures.

According to hearsay, it was Eanswythe who concocted the potion that poisoned Regna's first emperor Hareck before fleeing for Jadame. If that is indeed the case, then she must be at least six centuries old. Ordinary people don't live that long, and whoever this enigmatic crone is, everyone knows: she merely has to raise an eyebrow to make even the most formidable soldiers drop their swords and spears.
