Protection only goes to 40. Size only goes to 6. Morale only goes to 30 for mindful units. Strat move is maxxed at 12 for Vastness, IIRC. I think the others are unlimited, though it's hard to get magic resistance very high. There are also special stats, like reinvigoration, quickness, regeneration, fire shield, fear, awe, leadership, and so forth; I've gotten +302% quickness (after magical quickness multiplies in, it becomes 8 turns per round) and I think I remember making a mid-30's Fear POD once. Making a unit a prophet in a very high dominion area can sometimes give you that last bit of "oomph" for breaking a new stat record
