How to cast defensively

[Takamonk]

Since there were some changes to how magicians now work in a lot of arenas, one question I have is how does one cast defensively? It used to be a spellcraft check, but now it's not listed there. In the combat section, it explains what the DC is of casting defensively (which actually has nothing to do with the ability for something to hit you, so if you're immobilized, spit in the caster's face - ranged touch attack), but I can't seem to find where it is explained what you roll.

Thanks.

Casting defensively has changed from a Concentration check in 3.5 to a caster level check. It is:

1d20 + caster level + ability score modifier that modifies your spellcasting DCs

So I've heard, but I cannot locate this in the rules? Can you?

Under "Concentration".

there's a chart for all of the concentration checks, including casting defensively.

Silly me. I did read that section, but apparently I didn't let it absorb properly.

Thanks all.
