I like that, let's do it.
Updating the
Weredragon (True Drakanthrope) Working Draft.
We need to modify the
Changes to Statistics by Size Table since the true drakanthrope template allows for a very wide range of sizes in Dragon Form.
i.e. Tiny Base Dragon (brass wrymling) and Colossal base creature (mountain giant) for a brass mountain giant weredragon.
I would also allow for the possibility of particularly powerful weredragons whose base dragon stats and abilities are better than Wyrmling, such as a Young Adult Fire Giant weredragon or whatever.
We could do a matrix of sizes (i.e. hybrid form's size in column, dragon form's size in rows or vice versa) or just use size changes; i.e. STR –2 or –4 if one size smaller, –4 or –8 if two sizes and then add another –8 for each additional size change.
It seems more prudent to figure out some extreme cases and back-engineer from there.
So we need to decide on what ability scores are reasonable for the ridiculous extremities like a great wyrm gnome weredragon or wyrmling mountain giant weredragon and figure out a formula or matrix to achieve them.
Let's see, the SRD examples are:
Smaller dragons like the Black, Brass, Copper or White, which start out as Tiny wyrmlings with Strength 11 and go up to Gargantuan great wyrms with Strength 37.
Big dragons like the Red or Gold which start out as Medium wyrmlings with Strength 17 and go up to Colossal great wyrms with Strength 45 or 47.
I vaguely recall there being some extraplanar or spelljammer true dragons which bigger and/or stronger, starting out as Large sized wyrmlings or Medium wyrmlings with Strength of 19 or more but might be misremembering or thinking of non-WotC 3E dragons.
