OK, I'm doing this for the first and last time.

You may choose one or even more of these modifications for a Raziel (although officially no Raziel at the moment has more than a couple).
Retractile Claws: The Raziel's Trap Attack has a range of 30m and if it hits the target, the target is pulled in melee with the Raziel.
Spectral Shape: The Raziel can use the Spectral Shape as described in the Necromantic Level52 spell. Also, the Raziel retains full ability to affect the material world while in such shape. Those who cannot see spirits must pass a Notice Check against 120 or suffer from Blindness while fighting the Raziel in Spectral Shape. Spectral Shape can only be maintained for up to 1 minute.
Dual Raxxor Zero: Remove the trap attack and add a second raxxor.
Nova: Allows to do the two following things.
- Energy Distance Attack with full attack ability, 500m range and Base Damage 100. Attack used instead of the additional claw attack. After using this attack for one turn Nova cannot be used.
- Energy Area Attack with full attack ability, 15m radius and Base Damage 100. Attack substitutes all other attacks in a turn. After using this attack for five turns Nova cannot be used.
My suggestion, considering your party level is facing it with a mixed group including a few modified Raziel as "frontline", a couple high level necromancers and eventually even some powerful seekers (you will have to roll a few NPC). Since your players are pretty strong, the Black Sun might also choose to test some new wonder against them. You might take the Raziel NK-X and "improve it" by a couple levels, adding more Attack/Defense and more powers. But really when facing such strong opponents it's likely that Black sun will send undead forces supported by "intelligent" seekers. Besides, they might choose to send beforehand a powerful prowler (a Shadow or Assassin) to "spy" on them, in order to better study their weaknesses and combat tactics. If the hunting party includes intelligent beings, it's level of danger is greatly increased then if simply using a few raziel that randomly charge the party. If scouting on them is hard due to the Shadow and the Ranger in the party (but again, I believe such organization should have access to even better prowlers), then Black Sun should have no problems obtaining the services of a magician with clairvoyance to spy on them. If the party is really getting dangerous to them, they're going to use any trick they can think of. For example, undead cretures can be trained in the use of nemesis, and the same goes with Raziels, of course. If any of your characters are using ki techniques THAT would be bothersome. As an alternative, if you really want them badly dead:
send them a high level Illusionist or Dark Paladin with high Edamiel Elan, Seducer, Zen, tons of DPs spent on Persuasion and POISONOUS BLOOD...then have her seduce them to the bed...If the character is an Illusionist, you may add a Lower Resistances spell to the mix. Also a character could get close to them for a time (a classical character asking for help initiating a quest, just to come into possession of a part of each of them. Then, Vodoo on them from safe distance with Necromancers "at the base".
A strong fighters party shouldn't be fought by fighters alone. At least, a powerful organization such as Black Sun (which should be led by very clever people who control world's economy), should be able to think of better ways of handling them.
Of course they mght also send against them their best seekers...I believe Clover should be between Lev12-14 and possibly his "close" mates are around level 10. Black Sun isn't going against such a strong party without preparing a tactic that ensures winning the battle...
