Wisps are the traditional mage option, physically frail but one of only two monsters with a ranged attack at the beginning (the other being the Fanged Lizard's poisonous spit, which doesn't go as far). In terms of appearance it's like a Zelda fairy or just a glowing, floating ball of light, but even without limbs it can manipulate objects within its "personal space" with a very weak form of telekinesis. Because of its magical and formless nature, it will find it easy to take on different elemental traits for its Transformations.

The Pixie, in terms of appearance, is roughly based on the Shin Megami Tensei version (doesn't have to be a girl though). It's probably the only monster I would consider to have a big drawback, because even though it shares the Wisp's magical nature and accompanying frailty, it has no actual attack magic. It can only fight with physical strikes at first, which it doesn't have the raw stats to truly make effective. However, the Pixie is also the only monster that starts out with healing magic, and a supportive defense spell. If a Pixie player were to work together with another player, no matter their species, they would become much more effective.

[color=red][b]I'm going to make an edit in a moment to include the skills that each monster would start with, since that would probably help any character creation drafts.[/b][/color]
