e9n9 is the best. maybe earth mother pretender. But serpent cult has weak magic, maybe the weakest. Altough this blessed hydras are the toughest recruited unit in the game and i like it.

what about e9/n9 neifel jarls? they are tough. and yes it has poor magic and expensive units (and by making hydras good you limit your pretenders magic)
but tough ones are hard to get (w9 vastness ftw!). my f9 n9 centaurs might be ok vrs hydras multiple (very high strength when berserk) flaming attacks, regen and poison resistance (and my heirophant thugs have 5 attacks )
Its a little unfair to hydras because a n9 partially protects against their poison. They can't get a blessing to protect against fire, cold, or w9 lances
so, i could say giving the hydras f9 is unfair as it makes them better vrs my naturally higher def centaurs. N9 also gives +3 berserk (up to +6 for centaurs) and regen.
You don't really even need crazy-high blesses for the white centaurs. Dropping battle afflictions let's them get up to 5 experience without becoming useless. 40 White Centaurs, all at full experience with n6b4 handles most things.
