Dragon Size Attacks and Righteous Might

[Stephen Ede]

I'm running the Kingmaker Campaign and one of the PCs is a Dragon.
A rules Question has come up.

Dragons get Natural attacks and Breath Weapon area of effects based on their size. If they cast Righteous Might on themself do they gain extra attacks based on the increased size.

My view was that the increased attacks are only gained if the dragon grows to the new size as a process of growing up (or by some spell that specifically mimics growing up/older). Righteous Might merely magnifies your current form. Basically Righteous Might details what you get in the spell, and if it isn't there you don't get it.

My Player say that the Beastiary makes no such limitation on how the size is attained and simply says if the dragon is "x" size it gets "y" attacks, regardless how it gained that size. Thus anything that increases a Dragons size changes the natural Attacks and breath weapon area of effect.

Any help would be appreciated.

Thanks

Tell him he's only playing a dragon because you're a kind and benevolent ruler in the first place?

Dragon's increasing power I always saw as more a function of age than size, so I'd adree with your ruling.

" you're a kind and benevolent ruler "
Thank You. I'll remember that line. :-)
The party is somewhat unusual - 2 Silver Dragin Wrymlings (Twin Brothers), 1 Plains Dryad - Blodwyth, 1 Half-Celestial Slyph, and a Tiefling. It has interestig effects on a campaign when the PCs can't remotely look at the creatures they meet and say "Monster" without other party members responding "what do you want?". :-)
