You're good for creature control and healing. Unfortunately, you forgot to add in the damage.
You're overly dependent on that titan and your otyughs growing to a large size. Those two alone won't be enough. Consider using acceleration on armagio, and then using mitosis on that when you think you've grown enough damage. That way, you can keep the life/gravity and the control/healing, but you'll get a lot more damage out. Unfortunately, you'll have to get rid of the light if you want to do that.
