Behavior
Orion is a fire elementalist. This means he casts fire storm and other fire related spells in combat.

Orion is also a favored target of foes. Most monsters will target Alesia first, but those who don't target Alesia will usually go for Orion.

Orion is by far the easiest to kill in combat, due to his weak armor and inability to heal himself. The fact that he often quickly gets surrounded and attacked by multiple enemies only makes keeping him alive harder.

Tips

 * Try and keep Orion in the back of the fray. Have warriors charge in first and get the enemies' attention.
 * Target a lot of enemies that are bunched together. This way when his fire storm actually goes off, it will affect something living rather than the corpse of an already-slain enemy.
 * If you're not anticipating a really long battle don't even bother bringing him. He'll just spend three-quarters of every battle preparing his post-battle fireworks. I mean Firestorm.
