Mass hold person for the last 7th level spell it is!
Let's do moment of prescience and holy aura at 8th level. I was going with moment of prescience as the domain spell, but it works just as well as a regular sorceror spell.
Editing Working Spells
Updating Ahi the Steel Dragon Working Draft
Ready for skills and feats?
I guess the easiest approach is to compare him to his brother, who has:
Concentration, Intimidate, Knowledge (the planes), Listen, Move Silently, Search, Spellcraft (scrolls), Spot, Use Magic Device + (+ scrolls)
Ahi has a lot higher Intelligence so can max-out 16 skills, so how about we give him all of the above plus 7 more.
How about Bluff, Diplomacy, Knowledge (arcane), Knowledge (nature), Hide, Sense Motive and Tumble?
That'd make it:
Bluff, Concentration, Diplomacy, Intimidate, Knowledge (arcane), Knowledge (the planes), Knowledge (nature), Hide, Listen, Move Silently, Search, Sense Motive, Spellcraft (scrolls), Spot, Tumble, Use Magic Device + (+ scrolls)
Rahab's feats offer less inspiration since he's a lot more melee-focused than his brother.
Cleave, Devastating Critical (bite, DC 39), Fast Healing, Great Cleave, Hover, Improved Critical (bite), Improved Initiative, Multiattack, Overwhelming Critical (bite), Power Attack, Snatch, Weapon Focus (bite)
Of those, the only ones I've included in Ahi's stat block are Fast Healing and Improved Initiative. That leaves 10.
Feat 1 & 2 - Fast Healing, Improved Initiative
Feat 3 - Blind-Fight (It'll increase his chances of hitting Rahab through the Grey Dragon's aura of profane darkness aura.
Feat 4 - Multiattack (He's got enough attacks would be useful.)
I reckon most of the rest ought to be spell feats. Spell Focus and Greater Spell Focus in a couple of fields plus Quicken SLA and Spell Penetration seems a good basis, which leaves two feats undeclared:
Feat 5 - Quicken Spell-Like Ability (greater dispel magic
Feat 6 - Spell Penetration
Feat 7 - Spell Focus (Abjuration)
Feat 8 - Greater Spell Focus (Abjuration)
Feat 9 - Spell Focus (Enchantment)
Feat 10 - Greater Spell Focus (Enchantment)
Feat 11 - ???
Feat 12 - ???
What do you reckon?
