Elder-Basilisk said:Undetectable alignment is one thing. It will make the individual appear as true neutral if all alignment components are checked for (not lawful, not chaotic, not good, not evil). If you want him to actually detect as lawful and/or good, you need a misdirection based item.
This is the interesting thing for me. What does one get when you attempt to detect alignment on someone with Undetectable Alignment cast? The wise Elder Basilisk says true Neutral, but what if a 'true neutral' alignment is what the person is trying to hide? It is obviously suspicious if a detect alignment attempt comes back 'blank' (insert link to Order of the Stick here), but I'd like a clarification of what a hidden alignment reads as.
My house rule would be that a hidden alignment would appear as the caster's alignment, but of course that's not RAW.
It's also worth observing that hiding your alignment is not contrary to the Paladin code of conduct, however understood; it is not inherently evil or deceptive.
