Right, but it also says that dragon form only has the attacks of the base dragon (no matter the size), and the same for the hybrid form. So we can leave it in, but the way we have it written is not going to allow those attacks for any true dragon I know of.
A True Dragons' natural attacks depend on their size category not their LA, so I'm unclear why you think the current wording doesn't allow a weredragon in Large dragon form to use wings and tail slap attacks.
Would rewording it to be more explicit help?
Come to think of it, the Damage should be keyed to the dragon form's actual size instead of the base dragon. As written, a Cloud Giant Wyrmling Weredragon would only do Wyrmling damage regardless of the size of its dragon form.
How's this:
Attacks: Depends on which form the weredragon is using. Its default humanoid or giant form has the same attacks as the base creature. In dragon form, it has the same attacks as a true dragon of the weredragon's dragon variety and size category (see Size & Type). If its dragon form is larger than the base dragon it can gain additional natural attacks according to its size, such as the tail slap attack of a Large dragon.
A weredragon in hybrid form gains two claw attacks and a bite attack as natural weapons. A Large or larger hybrid form gains two wings attack, a Huge or larger hybrid form gains a tail slap attack, and a Gargantuan or larger hybrid form gains a tail sweep attack, if the base dragon has those attacks.
Damage: Same as base creature or base dragon, depending on which form the weredragon is using. As a dragon, it does damage according to the size of its dragon form rather than the size of the base dragon (as per a true dragon's Dragon Space/Reach, Attacks, and Damage). In hybrid form, the claw attacks and tail sweep attack have the damage of a dragon of the same size, while the bite, wing and tail slap attacks have the damage of a dragon one size category smaller.
What do we need next for these?
I was expecting to just work through it in order.
Which means Special Attacks once we've finished
arguing debating the Attacks and Damage.
