Anyone else find it odd Icarus's account is made today, for the sole reason of claiming to have emailed Richard Baker and the answer is you are immune to all spells cast at you, it is balanced though as it comes late in the game and it requires a few feats!
Would you rather me introduce myself, build up some posts, then offer some insight on a class I regularly play? I'm not here to court anyone, I saw an opportunity to share some knowledge I got from as far up the ladder as is probably possible and I took it; so don't look at it suspiciously just because its my first post. I'm not here to advance an agenda. Thanks.
Yes its on the strong side, and I'm not necessarily saying its balanced; but its the DM's job just as much as it is the player's to adapt to challenges thrown at them. All a DM needs to do is read the canceling effects on the Prismatic Wall table to see what negates the veils. An enemy NPC that first encounters an Initiate may not know what the hell is going on when a green shield pops up over a PC, but a quick teleport to escape (as villans often do) and some knowledge: arcana checks later; "Oh! That's the same thing as the green effect of a Prismatic Wall! I need to make sure to have
passwall prepared the next time I fight him!" Heck, a high enough Spellcraft check on the spot could give him the magical qualities of an observed effect.
And really, the most common spell on any caster's list is probably going to be dispel magic. Its a bit harder to make the check, but its all that's needed to kill the violet veil.
Not to mention the spells and items that specifically destroy prismatic effects, such as Disjunction and Rods of Cancellation.
Got a bit off topic, but I hope I brought up some helpful points for whatever you needed.
