I) Ritualist/Warlock is not able to be selected and/or shows up invisible.
S1) Install the Mod using DA Modder. DAUpdater and DAO Modmanager tend to skip the required Single Player background GDA files.
S2) You have a conflicting sys_chargen.ncs file installed somewhere.
S3) You can always use the "runscript ritualistx" or "runscript warlockx" console commands to transform a normal class into a Warlock/Ritualist.

I) The Ritualistx console command turns my character into a Spirit Healer.
S) You have some other Mod installed that edits the Spirit Healer Specialization. Figure out which one it is and deal with its conflicting cla_data.gda file.

I) The Warlockx console command turns my character into a Shapeshifter.
S) You have some other Mod installed that edits the Shapeshifter Specialization. Figure out which one it is and deal with its conflicting cla_data.gda file.

I) The Specialization are not be granted even when you meet the requirements.
S) You have a conflicting sys_chargen.ncs file installed somewhere.

I) The level-up screen does not show all the new Specializations.
S) The GUI will only show multiples of 4 Specializations. For example; if you have 12 installed they will all show up, but if you have 14 installed the last two will be cut off. This does not matter though, because the Specializations are auto-granted and not selected.

I) Hideous Blow is doing no damage.
S) You appear to have a conflicting rules_core.ncs file installed somewhere.

I) A passive ability bonus is not showing up on my inventory/character screen.
S) Dynamic passive abilities, such as the Arcane Archer's attack bonus and the Tempest's attack/defense bonus, will not show up there.

I) When creating a new Golems of Amgarrak character, I begin stuck in an empty room.
s) The abi_base_weaponfocus.gda is conflicting with one or more of Golems' added abilities. Since its files are encrypted, I'm not sure precisely which abilities are conflicting. Either temporarily remove that file, or temporarily disable this Mod.

I) The Charged version of the Ritualist's Inferno spell targets offscreen.
S) Center it on a target. It only does that when targeted on the ground. I'm going to replace it with something else eventually.

Q) Will ReSpec Mods work with the new abilities?
A) No. The "runscript removetalent #" and "runscript addtalent #" console commands work fine though. Awakening's ReSpec Tome may or may not work (have not tested).

Q) Where can I find the talent numbers that work with the above commands?
A) The abi_base_weaponfocus.gda or weaponspec_constants_h.nss files.

Q) Can I turn an existing character into a Ritualist/Warlock to test it out?
A) Yes. Use the "runscript ritualistx" or "runscript warlockx" console commands.

Q) How do I unlock Hellfire Warlock?
A) How do you unlock Eldritch Warrior, Eldritch Disciple, and Reaver?

Q) Why is the Genlock/Hurlock/Shriek/Ogre/Desire Demon/Werewolf/Wild Sylvan/Grand Oak model all screwed up?
A) It appears you have either shapeshifted into them using a companion, or with a custom player headmorph installed. Non-chargen headmorphs are not 100% compatible with the shapeshifting system.
