Converting DC's to CC's.

[KeyIXTheHermit]

My head hurts, guys. I'm sorry, I know this is probably simple math, but I'm just not up for it at the moment.

I'm thinking about using the tools at Donjon to run some quick games with a minimum of prep (and since we're just tunnel-bashing hack-n-slashers, that should work fine), but Donjon doesn't have a C&C subsection (careless of the site creator to overlook us like that...!).

I could just use the general d20 rules, but they aren't exactly the same, and the biggest difference is in the DC's. As we all know, DC's vary for C&C character, based on whether or not the task you're attempting is based on a primary or secondary characteristic.

My problem is that I'm just not familiar enough with D&D 3+ to figure out how the two systems compare. (I don't own any D&D after 2e).

If someone could tell me how they do it, I would be much appreciative. I might even name an NPC after you!

Thanks in advance!

If I were to use https://donjon.bin.sh to create a dungeon I'd use either the plain Fantasy or AD&D generators. But you can use the d20 one too of course. It's just wordier. See this thread: http://www.goodman-games.com/forums/viewtopic.php?t=785
.

For monsters, you can just look up the names in your Monsters and Treasure book and then it's all C&C from there. For treasure generation, see the one I wrote in my signature.

Ah, found it, thanks for the link:

I assume that DC 15 is the average DC of a check in d20. In C&C, the average difficulty of a task is CL 0. So every 1 the DC is higher than 15 in D20, the CL is 1 higher. So a DC 19 check would convert to a CL 4 check. For every 1 the DC is lower than 15 in D&D, the CL is -1. So a DC 12 check would be CL -3 in C&C. The CL of course is added to the base of 12/18 depending on if the character is prime in the required stat.

Yeah, for monsters, I'd just use the ones in the M&T or Classic Monsters book, so that's not a problem. I'm sure anything listed would be in one or the other.

The plain Fantasy one doesn't have descriptions, which is fine, because I can make my own sometimes, but when I want to just grab and go, having pre-made descriptions could be nice. The AD&D subsection is really light. I'm split between both that one and the d20 one, but I figure the d20 one will be generally more compatible (ascending AC's and all that), and I do like the excess information: it's easier to take things out than add things in when time is at a premium, imo.

It took me way too long to realize that all that really means is that you only need to subtract three from the DC to get the equivalent CC for a C&C prime attribute, or add three to the DC to get the equivalent CC for a C&C secondary attribute. Math Is Your Friend.

D20 had convenient lables of difficulty such that a DC of 15 for example was considered "easy" for level 1 characters (assume average roll of 11, +4 from skill ranks, + whatever from attribute). So... you would just use the chart of d20 to see "Oh, so DC 35 is "hard" for level 10 characters..." and compare that against the named categories in C&C to get something like "... so it must be 2 levels harder for these guys, being only 6th level. That makes it a CL of 12" (making up numbers.)

It can be easy. It can be hard. Which depends entirely on you.
