Tonguez said:If you look at the list given in the Detect Evil spell as per the SRD it is very specific as to what is detected viz
an Evil Creature is one with an Evil Descriptor eg Dread Naga, Huge Abberration (Evil)
Cymex666 said:Is the game better or worse for lack of alignment restrictions?
I imagine it would be a little difficult to run a game without the alignment rules because it seems (at least to my way of thinking) to me that the D20 rules are greatly influenced by alignment and its effects.
I read somewhere that the Unearthed Arcana (which I do not own) features rules for gaming without alignment, is this true?

shilsen said:No. An evil creature, for the purposes of the detect evil spell (which nowhere mentions it being a creature with the Evil descriptor), is any creature with an evil alignment. This was clarified in the FAQ, IIRC.
