I have the master archery perk that lets you paralyze targets and a paralysis bow. Is it possible for me to paralyze a dragon? In the time I've played I've not seen it and was just curious.
The master archery perk (Bullseye), paralysis poisons and paralysis enchantments do not affect dragons.
You can paralyze dragons. I'm not sure about the enchantment, but you can use the paralyze poison on them and they will stop moving.
