Version 1.39 of this massive custom content pack is soon to be released for Neverwinter Nights 2:
Of note, some serious love for Spirit Shamans:
Spirit Form (Spirit Shaman ability) now correctly lasts for 10 rounds as in PnP. It now grants a deflection AC bonus equal to the caster's Cha modifier. It also grants SR 11 + Character Level (to simulate the 50% ability to block both melee and magic from corporeal sources).
New Feat: Extra Spirit Form (+2 uses/day)
Chastise Spirits now correctly does 1d6 per SS level.
Chastise Spirits no longer affects allied spirits
Blessing of the Spirits can now be used at will.
New Feat: Extra Spirit Journey (+2 uses/day)
New Feat: Telthor Companion (for Spirit Shamans)
Other nice stuff:
New base class: Ninja
New PrCs: Dragon Warrior, Child of Night, Eldritch Disciple, Dissonant Chord, Ghostfaced Kiler, Dread Pirate, and Dervish
To replace the missing mount feature for Paladin:
Alternate Class Ability: Divine Spirit
In this release Monks also got enchantments to affect their bracers, which is great way to level the damage bonus playing field for them.
This will be a great release. Last release he added Fire Elemental "animal" companion, which gets bigger as it levels up, as well as the Ember Guard elemental shape for Druids, and fixed the Lion of Talisid PrC so that animal companion levels properly stack.
For anyone who doesn't have the game already, Direct2Drive is still selling NWN2 and Storm of Zehir (second expansion) for $5 each, although I would definitely recommend Mask of the Betrayer. Kaedrin's pack now requires Storm of Zehir, so if you didn't buy that expansion because the reviews weren't stellar, now would be the cheap time to pick it up.
