So I've attempted to convert an old friend to 4e. I used the level conversion guide and the expanded damage table, and then looked to Tiamat for guidance. I made all 6 swords everdancing because I thought the image would be cool, and I reduced Alabaster's speed based on how Tiamat's speed was reduced from 3.5e.
This entry does not convert the Amidah template, just Alabaster himself. How does it look?

Medium natural humanoid (undead) XP ???
Initiative Special, see Sextuple Actions, below Senses Perception +29
Evil Eye (Gaze) aura 20;
all creatures Alabaster choose take -2 to AC, Fortitude, Reflex, and Will defenses. They also take -2 to attack, damage dealt, initiative, saving throws, and all skill checks.

see Mist Discorporation and Co-ordinated Strike
Regeneration 10
AC 55;
Fortitude 55,
Reflex 55,
Will 50
Immunities Cold, Fire
Saving Throws +5
Speed 12
Action Points 6;
each sword can only use one action point, and Alabaster can only spend one per round
Blood Drain (standard, encounter; recharges when an adjacent creature becomes bloodied) * Healing
Requires combat advantage; +43 vs. Fortitude; 2d12+30 damage, the target is weakened (save ends), and the vampire lord regains 440 hit points; see also combat advantage.
Dominating Gaze (minor, recharge

) * Charm
Ranged 5; +41 vs. Will; the target is dominated (save ends, with a –2 penalty to the saving throw). Aftereffect: The target is dazed (save ends). Alabaster can dominate only one creature at a time.
Mist Form (standard; encounter) * Polymorph
Alabaster becomes insubstantial and gains a fly speed of 12, but cannot make attacks. The vampire lord can remain in mist form for up to 1 hour or end the effect as a minor action.
Mist Discorporation * Polymorph
When Alabaster becomes bloodied, he and his weapons become discorporate into mist and gain a fly speed of 12. He cannot attack or be attacked by any means during this time. He can remain in this form without limit, but cannot reform for a period of time immediately after becoming mist.
Co-ordinated Strike (Immediate reaction, when first bloodied; encounter)
Upon being bloodied, all six weapons immediately gain a move action, a standard action, and a minor action. They still activate as normal on their initiative counts. This ability only activates if Alabaster is not in mist form. At the end of the round, Alabaster regains any action points he has spent in the encounter so far.
Sextuple Actions
Alabaster does not roll initiative as normal. His swords have set initiative counts of 50, 45, 40, 35, 30, and 25 (Alabaster chooses the order each round). He cannot delay or ready actions. Each sword can activate once per round on its initiative count to take a standard action, a move action, and a minor action. Alabaster himself can activate once per round instead of a sword, or, if he takes a sword in hand, he and the sword can act together. Alabaster’s ability to take immediate actions refreshes on each head’s activation.
Intelligent Weapons
Each time Alabaster would become dazed or stunned, he loses his next sword activation instead. Multiple such effects do not stack.
Limited Range
Alabaster's swords cannot purposely fly more than 6 squares away from Alabaster. If forced to move farther, or if left behind, they must spend any available actions on their initiative in order to return to within 6 squares.

Upon a critical hit, target's divinity is sundered until the end of the encounter, creating an appropriately sized Quintessence Elemental for the duration.
