Weird. In the case of Constructs for example, CON -- seems nothing but a benefit. Constructs get bonus HP to make up for the lack of CON modifier to HP anyway, and the missing CON makes them immune to a bunch of effects...Krishnath said:Non-abilities are calculated as if they where +0, so if a creature lacks con for example, it is considered to have a con modifier of +0.
Oh, that part I totally agree with.Krishnath said:It is not weird, Constructs and undead lack a metabolism, and thus cannot have a con score.
