Cleon
Legend
Well, I agree that lesser planar ally would actually be fun but may be too ambiguous. I guess let's go with summon monster IV since we've decided he doesn't really like to get involved in melee.
I can go along with that.
Updating the Hanim Worm Lord.
So many good choices for the remaining 5th level spell. But maybe we should stick for the simple mass cure light wounds. That or maybe wall of stone. What do you prefer?
Well mass cure light is serviceable but not exactly interesting. I could see wall of stone being used to build platforms for Hanim settlements, bridges and other conveniences so that is more tempting to me.
Let's see, I can see Zophiel being the type to impose mark of justice to enforce his commands and break enchantment and true seeing are always handy. (He doesn't have any way to see invisible at the moment which is an argument for true seeing)
So I'd go for wall of stone or one of the three above spells. What's your preference?
