There are only 3 summoning spells, Shining Blades the epic looking not epic spell, Ice Hammer, and Flame Spear.

It does seem awfully weak. However, Knoc can use all the arcane spells, so flame spells, Ice spells, Energy spells, mind spells.

Once you multiclass mage, sorc, wiz, conj, knoc becomes a plate armor wearing mage. It's very powerful.

I like the idea of a summoned pet that gives a buff. So it would just sit in your effects window. Not sure it the tech exists to create a visible pet. But if it did I think that's a cool idea. Maybe just a slowly rotating about the player effect... would give the appearance of a pet without necessarily being a pet object. Would just be a graphic effect. If the effect was like an animation effect that played for 10 minutes before it started over, it could mimic being an actual pet. Pattern wouldn't be obvious.
