Currently only Rinny teaches spells, but you can get some passive skills from other NPCs in the game.
drain kiss does drain stamina though?
Drain removes it from the enemy but does not give any of it to you.
So I'm not sure if it is really "drain" think final fantasy drain spells (if that was what you intended it only does half the effect) even Warcraft describes it as "
Definition
Drains do exist in two forms: Mana Drains and Life Drains. The definitions of those two normally slightly differ. Common understanding is:
- Mana Drains are abilities, which remove mana from the enemy's mana pool. They normally have a secondary effect.
- Life Drains are abilities, which transfer life from the enemy and add it to one's own.
Currently, almost all of these spells are Shadow spells."
However yours only does the first part "remove life from the enemy" but does not add it to yours.
you said it would be too powerful. I take (in some cases) 8 hp damage at a time if the spell only recovers 3 then that's not overly helpful as a restorative option. Also I notice that the NPC doesn't seem to have a limit on their MP (I could be wrong) but it seemed they were able to use them constantly without pause. Final Fantasy 2 (US or FF4 Japan) made a great point of showing bosses had a MP limit (Fight Asura) cast wall on her and she'll keep using cure 4 until she runs out of MP
