Vampiric Drain is a unique Novice Destruction spell that continuously absorbs a small amount of health from a single target and adds it to your own. While Vampiric Drain can be dual-cast with the corresponding Destruction skill perk, its cost is not reduced by any Destruction proficiency perks and using it does not train your Destruction skill. However, equipment and apparel reducing Destruction skill costs will still have effect, making it possible to cast Vampiric Drain for free. Unfortunately, this spell is not as powerful as the version cast by vampire NPCs (which can reach up to over 20 HP per second), but it can be useful to damage an enemy while healing yourself, especially at lower levels, avoiding the inconvenience of having to switch to individual spells.
