Rather than have an advancement section for these beasties, maybe we could allow them to be created from 5th or higher level fighter.
Hmm. Sounds like I'm pushing this back towards a template. But maybe a Prestige Class (for any worshipers of Ragarra with a BAB of X) could do the job.
I think the lesser segarrans are not quite sophisticated enough (in design, not in Int

) to be templates and especially not PrCs.
As the abilities of the beastie improve as the cleric goes up in levels (wings at 16th level) I wonder if a Prestige Class might be a better way to handle this.
A PrC is an interesting idea for the greater, but the problem I see is that most of the transformation seems to happen right at the beginning.
The 9 hit dice is a bit confusing. It would make mewonder if the Greater Segarran is created from a 9th level cleric, but lower down the text, we get told that they are created from 12th level clerics. So what happens to the other 3 hit dice? I thought the +18 was hit points Is the +18 actually another 18 hit dice? If it is 18 hit dice, then I'd say that the stats were for an 18th level cleric.
I'm guessing that the 9HD (rather than 12) is an artifact of older edition monster design.
I think this should somehow feature in the conversion. If the segarran can open some sort of doorway to Ragarra this ability should return. Alternatively we could offer it as an advancement option (especially if this monster got turned into a Prestige Class).
I'd make this a flavor issue or maybe a variant lesser segarran.
Perhaps the Organization section of the Greater Segarran should include an escort of Lesser Segarran.
At least as an option, yes, I love this idea.
Looks like killing a segarran and using spells to bring them back from the dead would make them human. But as they go into this process willingly, I'm not sure they would want that to happen.
I think the idea is that breaking the "curse" is a way to attack them, not anything they would actually want to happen.
This is looking more and more like it should be a PrC to me.
Standard spellcasting rules allow a cleric (or any other spellcaster) to cast lower level spells in
spell slots, so I'd say that a 13th level cleric (who gets 7th level spells in 3rd edition) should be able to use the 7th level slots for 6th level spells.
Yeah, this is an interesting point. There's the difficulty I mentioned above, but I could possibly see the greater segarran as a PrC rather than template.
Would the tail affect flanking (i.e. can't be flanked)?
Normally it's things like extra eyes (ability to process more information) that makes a difference with flanking, not having an extra body part or attack.
Should we swap the bat wings for dragon-like wings (to make them more reptillian)? If there is nothing in the blurb of Ruined Kingdoms that associates Ragarra with bats, I say we should make the swap.
I could see a swap, but the bat wings on a croc are nice and creepy.
