Thanks Walking Dad. I'd noticed the inclusion of monsters into the PRD earlier and have already incorporated the updates, the few that there are, into my character sheet. BTW, Bronze dragons previously had the water subtype.
CB, there are a few elements that change for my character's monster class, albeit mostly in later levels; the most straightforward of which are feats. In Pathfinder a character gains a new feat every two Hit Dice instead of every three. For a bronze dragon that means a feat at 1st (no change), 3rd (no change), 7th (instead of 9th), 11th (instead of 13th) and so on.
Two other significant changes pop as well. Oddly perhaps, a bronze dragon's ability to
speak with animals at will has been delayed from the
wyrmling age category (as it was in 3.5) to the later
very young age category. For the Bronze Dragon monster class that means that the ability is gained sometime after 10th level instead of at 2nd level.
Lastly, the only other change to the bronze dragon wyrmling (as far as I can see) is that its Dexterity score increases by +4 (from 10 to 14). That would mean that two +2 Dex ability score increases should be added to the monster class' level advancement somewhere between levels 1 and 9. Good spots to add them, in my opinion, would be levels 2, 5 and/or 9 since those are the levels without any other ability score increases. I'd suggest the first be gained at level 2 to compensate for the loss of the
speak with animals spell-like ability.
CB, please let me know your thoughts on these changes.
Walking Dad, please let me know if I missed some other change to the bronze dragon between 3.5 and Pathfinder.
