Steely Dan said:Okay, then the same goes for the dragon that chose not to learn rope trick or alarm etc.
Are you suggesting that all dragons should have an innate alarm/warning type spell-like ability?
And how does the dragon learn those? Taking levels in wizard?
Imo dragons should have the innate ability to learn/cast some spell because it simply makes sense for them as otherwise they are extremely handicapped outside of the combat.
Dragons having rituals is probably the best idea. That way dragons can cast utility spells when needed but their combat ability is not affected by spells so the people who want the dragon to just be another encounter don't need to bother with them.
