Remove the animation from Drain Life, add it to Torment

[milski]

By the time you encounter it, Drain Life is a relatively weak, negative-energy smite that heals the Soul Eater that casts it. The fact it hits all allies is irrelevant for most characters and still adds very little to the threat for summoners. Giving such a mediocre spell an animation is confusing and doesn't really convey any useful information to the player.

Torment, on the other hand, is an extremely powerful effect at all stages of the game. Further, it is specifically nonlethal, which makes it valuable to know if e.g. you lost 40 HP that turn because of Torment or because something really nasty hit you. Adding the brief dark "flash" to any Torment effect would provide a simple visual cue for one of Crawl's most potent effects.
