Yeah, I wasn't really certain if there was a DC for it already, given the less than clear wording of much of the text for the class.
I do agree with you that just banning ConGate entirely would be the easy way to handle things, and probably the right way -- Truenamer isn't anywhere remotely near T6 if you allow the use of things to get around the scaling issue, though by the same token the bulk of the class isn't good enough to compete with T1s either. Especially when the other options from LotPM are still decent, though not brilliant, considering that AtSE is easy to save vs. or avoid at this level, though it has some good applications as an armykiller.
Deny Passage, though, that's super fucking vague. From the description it sounds like PfE targeting a location rather than a creature, with no alignment restriction, but I have no clue if it also blocks possession attempts through the barrier, or if it grants the deflection and save bonuses to creatures on the opposite side of it from the creature or creatures being contained for attacks through it. Likewise, the description says that the target is unable to interact with the barrier, but does that prevent it being overcome by SR? It shouldn't, but the text is so poorly written... ;.;
I suppose we'll see what happens when Tawa checks in.
Oh hey, ninjas.
But yeah, Harbinger, do you have any more of a clue about what the hell is going on with Deny Passage's text than I do?
