Doom currently uses one animation for every neutral creep spell he gets. For some of them, the animation is fine and fits. But for others, it's unfitting.

In the best case, every spell should get its own animation, but they can still be grouped:

1. Mana Burn, Purge, and Chain Lightning could use the level_death animation (currently unused since the spell was removed)
2. War Stomp, Thunder Clap, Slam, and Desecrate (and maybe Raise Dead) could use the slam animation (currently used by Scorched Earth)
3. Hurl Boulder, Shockwave, Tornado, and Ensnare could keep the current animation (the throw animation fits them the most)
4. No idea about Heal, Ice Armor, Frenzy, and Fireball
