Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

Can someone please help point me to a guide or thread that explains how caster DC checks work on BGTSCC? I believe the mechanics were customized about a year ago, at which time there were lots of posts about the changes. I'm just not having any luck finding those posts.

There is nothing custom about spell DC's... Are you talking about Caster Level checks for Dispel mechanics? We did implement a dispel fix last year which makes it so you have a true caster level, instead of character level for purposes of dispel.

Ahh, that must be what I was thinking of!

Dispel checks work like this:

Caster of Dispel rolls d20 + CL vs. DC of 11 + CL of the one being dispelled. If the total of d20+CL of the dispeller matches or beats the total of 11+CL of the one being dispelled than that ward is dispelled (rolled independently for each ward).

Lesser Dispel is capped at +5
Dispel is capped at +15
Greater Dispel is capped at +20
Mords is uncapped (and also has breach mechanic to auto remove 6 buffs from the breach list).

So a CL 20 or higher Greater dispel that rolls a 20 has a dispel check of 40. A CL30 caster has a dispel DC of 11+30=41. Thus CL30 is immune to Greater Dispel, but not immune to Mords. Likewise a CL25 caster is immune to Dispel and CL15 is immune to Lesser Dispel.

Thanks Chad, much appreciated.
