Sure, but don't dismiss the sheer power difference, either. This post has been up for a few hours and the general feedback so far is that it appears to be an unbalanced new class. Sure, people would have to apply - but those accepted (with the way the PrC is currently written) would be miles ahead of characters of equivalent level.
IMO, if the team is going to implement new classes, an attempt should be made by the devs to ensure it's not overwhelmingly powerful. This PrC seems to be, to me.
General feedback consists of aporg and yourself posting multiple times in this topic. That's not general feedback, it's the opinion of two people.
On the Dirgist:I'll provide some more diverse feedback (I'm also probably the "big bard" around right now?). The dirgist is interesting and compelling, but the lack of advancing spell selection 100% holds it back from being as good as a pure bard. The 5th-level and 6th-level spell slots can't even be used on metamagick'd spells for bards in most cases, as Wounding Whispers cannot be empowered and Sound Lance is rarely used and has a terrible DC. The 6th-level slots would just end up being used to cast Empowered Cure Critical Wounds, if anything, which almost feels against the spirit of the PrC.
The lack of improving Reflex is a wash. It's a loss, but not very painful.
The loss of Tumble is also a wash.
The requirement of Endurance is a feat tax. Almost every PrC has them, moving on.
The loss of 1 1st, 1 2nd, 1 3rd, 1 4th, and
all five fifth and sixth-level spells known as a bard 12/dirgist 8 is absolutely, irreparably crippling. This loss is so inarguably, insanely bad that even if this prestige class had full base attack bonus and gave a bard a 1/day Wail of the Banshee, it would still be bad compared to the utility of mass animal spells, ethereal visage, healing circle, great dispelling and mass haste.
The new performances are interesting options. Crescendo of Blood is obviously the "big kicker", but given the (max) 1.5 minute duration of bard songs, it would give at best a +2 or +3 bonus to AB and damage while eating into uses of bard song that can be used to also boost saves, use Curse Song or give allies temporary hit points. I would apply for this prestige class on my long-standing Akiri bard. I find the flavor fairly compelling,
although losing out on Ethereal Visage and Mass Haste would stink!Conclusion:Spells on PotM are king. Losing spell selection is invariably a loss in the grand scheme of taking this PrC. The 7th-level ability is completely worthless, although cool. It is irreparably worse than the bard overall, and it will undoubtedly lower the power of your character by taking it due to the long-standing issue of being unable to progress spontaneous caster spells known in NWN using prestige classes. Please, stop blindly talking about this PrC like it's powerful, guys! Even a bard 15/dirgist 5 (a level 20 character) would know no 6th-level spells in exchange for debuffing abilities that are mostly situational and a bardic performance that's useful for hiding from undead, most of which can be bypassed by a simple Invisibility.
If I may make one
(implementable) suggestion, please provide the Dirgist with the ability to cast Dirge as a spell-like feat. It seems an almost ironic tragedy that the pinnacle of bardic necromancy would be unavailable to the dirgist.
Thanks for more cool custom content, EO and dev team! Cool stuff like this is why I play here, it really makes my day!
An aside on the Hallowed Witch:On paper, it's better than a straight caster, but worshippers of Hala are locked out of the "broken" clerical domains, Hallowed Witches must start as wizards or lose their spellbooks every time a Hak update happens, and the ability spread requirements leave players of this PrC physically crippled. The classically renowned Divine Power + Tenser's combo would be powerful, but the pacifistic nature of a Halan basically makes you fall by using it.
The reduced spellcaster level compared to a pure caster makes dispelling even more painful, and the late arrival of critical spells for dungeoning such as mind blanking and death warding means a Hallowed Witch is only useful for dungeons they are already massively overleveled for.
Hallowed Witch makes a good invisible healer, not a good substitution for a wizard and a cleric.
