Infinite Variety combos, suggestions?

[Learn2Roll]

I'm talking about the class feature of the master transmogrifist(complete arcane) for those not in the known , this class features allow to add one extraordinary special quality, one extraordinary special attack and one form of attacks (for example if I choose the twelve headed hydra as my secondary form, I can add the fast healing and the 12 bites to my war troll form primary)

1)Twelve-Headed Hydra (12 attacks, fast healing, enough said)
2) War Troll (very good stats and regeneration extraordinary+ the stunning blow)
3) Firbolg (good stats mostly)
4) Will O Wisp (because of magic immunity(Ex) and Natural invisibility (Ex))

I'm trying to fill the last 3 spots with monsters that could offer good extraordinary special qualities and if possible one good extraordinary special attack, I was thinking of doing the classic combo Giant Octopus + Mind Flayer for the extract(ex) but open to suggestion.

CHOKER for QUICKNESS.

If you don't do that, I will hurt you in such subtle ways that you couldn't possibly understand them without 2 standard actions per round.

[Learn2Roll]

damn I knew that I was forgetting something, the quickness is indeed an (ex) ability, awesome man!

It's (Su), though.

[Amechra]

F**k. Alright, grapple with a throttle.

Depending on how you interpret the sharn's inability to be polymorphed into text, you might be able to pick up (ex) Independent Action.

[Learn2Roll]

the sharn, I'll look it up.

Anauroch, Empire of Shade.

I'd still rather pick the Hex Portals. Not as powerful, but 3x cooler.

Yeah, but (su).

Assuming you can get construct forms, Zodar (FF) for Invulnerability (applies to all attacks except bludgeoning weapons.)

If you have room, Ocean Giant (MMII) for immunity to bludgeoning weapons.

Hmm, you do any crafting?  The midguard dwarf has the Master Smith EX ability.  You get craft magic arms and armor, craft wonderous item, forge ring, and you are considered to have all the necessary prereq's to craft anything.  It would be a decent form during down time.

I was also excited about the Curst from Lost Empires of Faerun, but it turns out to be a template.  Unkillable EX means you can only be killed by total body destruction or to remove the curse that keeps it from dying.  No undying curse so only full destruction would work.

Edit: Mock Divinity EX from the lilitu in fiendish codex 1 stats the lilitu casts spells as a 9th level cleric,  but she uses her Cha for spell casting.  The ability goes on to describe additional casting things she does, so I think you could use this to pick up spell casting.

I would go for some kind of good movement mode, possibly Xorn's Earth Glide or something like that. It could get you out of a sticky situation or two.

I'm a sucker for the remorhaz ... special quality (ex) = heat (creatures that you grapple or who attack you with natural wpn take 8d6 fire damage; wpns that strike you fort save DC 18 or be destroyed).

[altpersona]

can has pixie? (ex) invis?

[BeholderSlayer]

can has pixie? (ex) invis?

He already has that covered with Will-O-Wisp

Phaerimm, gives you sorcerer spell casting equal to your HD, or adds it to your existing sorcerer spell casting. Also, all your spells now work as spell like abilities when it comes to casting time (standard action casting) and cost (no material cost, or xp cost)

[Jelvoden]

Unless I'm missing some errata on the subject, you only get one ability of the secondary creature for the transformation. So in your example, you'd only get the hydra's fast healing or the 12 bites. By the "last 3 spots," I assume you mean the favored shape options. Keep in mind that only the base monster has to be a favored shape, and the secondary can be any monster that exists in your campaign setting (possibly limited to those your character is aware of, depending on the DM). The relevant passage is:

"... To create an imaginary form, he chooses one of his favored shapes as a base form. He can then chose a single aspect of a second monster whose form he could assume using the spell he is casting and add it to the first creature. His available options include..."

Save your favored shapes for creatures that have boatloads of good abilities, then just cherry pick the singular best abilities from the monster manual for any given situation, as you need them.

[The_Mad_Linguist]

Ah, well that precludes using sharn abilities.

Aspect of Demogorgon [Miniatures Handbook] gives Dual Actions as EX, it's an Outsider with 11 HD, so you'll need some manipulation for "early levels", like Otherworldy feat or being a Neraphim.

Chronotyryn [Fiend Folio] Dual Actions and Choker's Quickness are both SU, so it's no good unless you use them as primary form with Assume SU.

Chronotyryn [Fiend Folio] Dual Actions and Choker's Quickness are both SU, so it's no good unless you use them as primary form with Assume SU.

Incidentally, what if you put them both on a single creature? I'm guessing that each says "may act twice" or "may take two of each action", but if they say, "may act again" or "may take additional actions" or something like that you could have some fun times. Also, the Thoon Elder Brain has an interesting variation, if you have lots of Stilled, Silent spells or buffs.
