Hi,
The umbral dragon gains darkness as a spell-like ability.
When?
In the table, darkness is mentioned at age category very young (2), but in the following text, under "spell-like abilities", it is mentioned at age category young (3).
I guess very young would be correct, since that would mean that a spell-like ability is gained at every second age category (2, 4, 6, 8, 10, 12).
Thanks in advance!
I think you are right. All other primal dragons have their first spell-like ability at the very young category, so I think umbral dragons probably should as well.
