Method to Acquire - Starts with you on Chapter 21.
Damage - As sad as it is, in my Hard Mode file, Saul had 17 magic, 2 lower then level 20 Bishop Yodel. So it's pretty good.
Critical - His natural critical isn't that high, but nearly every light spellbook has a critical boost.
Speed - His speed is AWFUL. He starts with 14, so you're going to need to give him speed increasing items, which appear in the Secret Shop on Chapter 21.
Dodge - His dodge is very bad, but if you are up against a spellcaster, they won't do any damage to him because he has maxed resistence. Just be worried if you're fighting an enemy unit with weapons at a 1 panel range or an Archer at a 2 panel range.

Rating - 7.5/10. He has pretty high magic for a Bishop and he starts with an A in Light Magic and an S in staffs, so he can use Holy Maiden immediately and Aureola pretty quickly. Additionally, Ellen and Saul are difficult to raise and often end up far worse than their averages for me.
