I know that the Warlock Invocations are a big mess, but...this is just something to note (and hope for a change).
According to the SRD:
The BGTSSC doesn't have "nauseated" effect, but instead:NOXIOUS BLAST
Greater; 6th; Eldritch Essence
This eldritch essence invocation allows you to change your eldritch blast into a noxious blast. Any creature struck by a noxious blast must make a Fortitude save or be nauseated for 1 minute.
Issue here though is ESK is 5 on BGTSCC, when it should be 6.Cursing Blast 5th ESL
Noxious Blast: Fortitude save or suffer the effects of being dazed for 4 rounds. A dazed creature will do nothing except defend itself.
Maybe a very easy edit??? If can be done, let me know, and I'll update the Wiki. Thanks.
