I pretty much only use cleric hirelings, the warriors are too squishy or stupid, the sorcerors and wizards have no sense of self preservation and wont evade big baddies coming to mush their brains.
So heres a few tweaks to the spelllists for the hirelings (level 4-15)
Malone lv4 : ok
Kendra lv5: Good, useful spell list.
Molin Lv5: Bad spell list, I suggest changing it to: CSW, Remove Curse, Remove Fear, Remove Disease (a themed healer for mummys)
Arias lv6: Pretty useful, though you could change cmw to some other level 3 spell maybe blindness.
Mareth Lv6: Bad spell list: I suggest changing it to : Glyph of warding, Protection from evil 10', Mass Aid, CSW (a themed warding cleric)
Flower Lv7: Pretty fun and useful spell list, I suggest only changing turn undead to DIVINE CLEANSING II.
Laerathor lv7: Good, Useful spell list
Fergus lv8: Bad spell list (because it's basically a duplicate of flower): Suggesting: Holy Smite, Order's Wrath, CCW, Summon III (hellhound) (themed damage dealing cleric)
Marrisa + samuel lv 9: Both fun + useful spell lists.
Fayden lv10: Boring spell list: Suggesting: Chaos Hammer, Raise, CCW, Slay Living (themed dark hearted cleric)
Arkyn lv11: Good, Useful if slightly boring spell list.
Flagon Moren: Useful spell list.
Dheryn: Useless spelllist: Suggesting : Heal , Symbol of Stunning (or weakness) , Summon VI (troll), Raise Dead (themed conjurer)
The rest are mostly ok until
Isadora lv16: Change blade barrier (flagon moren already has it) for Holy Aura or firestorm or summon VIII (bezekira) (she's a cat lady).
