A little love for the Warlocks out there:
Chilling Tentacles [CArc p. 132]: Greater invocation, equal to 5th level spell, functions like Black Tentacles (which allows no SR), but also causes 2d6 cold damages to all creatures in its area, a 20' radius spread
I though all invocations were SLA's with SR?
black tentacles spell, except that each creature within the area of the invocation takes 2d6 points of cold damage each round."
The Black Tentacles spell description states that it does not allow a save and does not allow for spell resistance.
As written, this creates a complete textual contradiction. Does the statement in the class description control or does the statement in the invocation description control? Both descriptions are definite statements. The Chilling Tentacles text does not specifically state that SR does not apply; however, the same text states that it functions identically to Black Tentacles, except for the additional cold damage.
If the statement in the class description controls then the invocation DOES NOT function identically to Black tentacles.
If the statement in the invocation controls then the text of the class description is rendered meaningless in this instance.
Therefore, this requires a DM's ruling.
In my opinion, though, it doesn't even come close to throwing off class balance to allow the Warlock a no save/no SR AoE invocation of this type. 2d6 no save/no SR damage gained at 11th level, at the very earliest, isn't overpowering. If I was the DM, I'd let the invocation text trump the statement in the class description. YMMV.
As an aside, interpreting WotC handbooks is a lot like interpreting cases and statutes. Sometimes it's even harder.
