Samrata Scramge

Samrata Scramge is a Rakshasa who lives in Rappun Athuk, near the purple worm den. The party has encountered him twice to date, both times resulting in a sound defeat. He employs a mix of up to 9th level transmutation and illusion magic, some quickened, and he can cast greater dispel. He has DR 15(?) Silver+Good, and has a massive SR. 
Two splat pieces relating to him, both written by Alex:

So, what do we know about Scramge, assuming there's only the one Rakshasa? 
That assumption seems to be a good one, Raksashas are like Siamese fighting fish or Kardashians, they do not play well together.''
First and foremost they are egotists of a grand scale. Raksashas are divided up into classes, depending on their ability. The classes are (in ascending order):
Raktavarna, Dandasuka, Marai, Common, Tataka and Maharajah.''
Sight alone is not enough to distinguish between the classes, as all from the level of Common up spend considerable effort looking like a powerful Maharaja. (The lower three classes look like a serpent, a fiendish gnome catgirl, and a snake with snake for arms, respectively).
Nor can one trust a rakshasa's word, as they are liars of the highest order, and the worst kind: they almost certainly have internalized their own lies as truth long ago. You must instead look at what they can do.
Scramge is certainly a Maharajah rakshasa, Maharajas are spellcasters first and foremost, focusing on a school of magic then branching out. Illusion is the prime choice, with enchantment and transmutation coming in a tied second. Every Maharajah is different however, having spent their time learning a distinct set of spells, although they accrue more as they age.
Scramge favors phantasmal killer, dispel magic, and polymorph any object for his offense, and almost certainly has access to true seeing, comprehend languages, and a variety of defensive spells. Rakshasas are not stupid - but they are proud, the kind of pride often only reserved for dragons and devils; those that know that they're extremely good at what they do.
Scramge does carry a falchion and is probably pretty good with it; although a rakshasa that's been reduced to hitting someone with a bit of sharp metal is not going to take prisoners - the damage done to the attacker's flesh will be nothing compared to the damage to the rakshasa's pride.
Defensively (besides his suite of spells), Rakshasas enjoy ignoring a lot of damage that's not dealt by a good piercing weapon. His spell resistance is godlike; rakshasas consider themselves masters of magic and magic seems to agree.
While Scramge definitely favors tricks, it's almost certain that he has more up his sleeve than simple weird spell. Rumors of a raksasha in Rappan Athuk are centuries old, and there are stories of maharajas going toe to toe with balors gleefully.
Perhaps this is one that goes in the same pile as "the bottom of the Well" and "Tabitha's undergarments"; maybe this is beyond the reach of mere mortals.

Samrata Scramge was not born a Rakshasa, but even they do not remember what they once were.If Scramage had a day for every year they lived, they'd still have more years than Kruin, twice over, with some to spare.Scramge is not their name, nor is Samrata. Scramge is the name of his prized possession, although it is not what it once was, having broken along with all it's kind.Samrata is a status; it means a Maharajah who has slain 3 members of 3 species, each creature older than they. Rakshasas are one, and Dragons are a second, the third may be devils.Scramge found his home a long time ago, but his home only moved to Rappan Athuk when the Oracle did. Scramge gave much of his wealth to the oracle to find the remaining creatures to allow him to earn his Samrata status. He paid the oracle a gem worth kingdoms not to divulge his secrets. The last laugh was had by the oracle; The oracle had no power over things older than the oracle's demise.Scramge has spent too long seeing the Truth; he can see someone's soul, and so has forgotten how to see faces. He has never made anything real in his life, nor commissioned anything to be made. He sees the world as his to take from, to ask for something to be made for him would to admit that the world does not serve him first and foremost.Scramge once took tea with the Grand Cornu of Orcus, when the Orcusites arrived. Scramge has never turned down an offer of tea, as was not about to begin. Far from thinking it was out of politeness, the Grand Cornu assumed it was because Scramge craved attention, but did not understand it; civil tea and attempted assassination were equivalent to him. The Grand Cornu gave him the magic crown that he still wears, wrongly thinking that Scramge would join his cause, although Scramge has never explored Rappan Athuk beyond the small area he considers to be his.Scramge thinks himself a god; and gods dislike things as old as he, so none have corrected him. His pride and his intelligence are nearly equal, but he has never come close enough to death to learn at what point his own pride would lay him low.Scramge loves games of skill, but no story mentions him losing. Rakshasas are not graceful in defeat.
