Effects of aging from child to adult

[Nightwish]

Does anybody know where I can look for effects of aging from child to adult? The PFRPG rulebook lists ability modifiers from adulthood on forward, but doesn't say anything about moving from, say, a young teen to an adult. I've got a yuan-ti (thelassakar, the lawful good variety) npc who was acquired as an orphaned child but has just reached adulthood (age 12 for yuan-ti). Should there be a net zero ability adjustment across the board, or should there be some adjustments?

You could do the inverse of the young creature template, if you really want a mechanical representation of reaching adulthood.

I saw one for newborn-child-preteen-young adult one time and cannot find it again.

Use the monster advancer from Pathfinder SRD. It has a young, very young and extremly young template.

I dont know where you find the RAW but maybe it helps.

This. It comes to size +1, natural armour +2, strength +4, dexterity -4, constitution +4. A net result of -1 AC, +2 hp/hit die, +1 to attack rolls (unless it was finessing earlier, in which case its a loss of -3) and +2 to damage rolls.

You could also take a look at the dragon aging rules and extrapolate something from that, so as to also improve the mental abilities of the NPC. A further choice would be to give it a class level, which would automatically give it stat increases of +4/+4/+2/+2/+0/-2; that's if you don't want it to grow just yet.

There's one of these in the D20 modern core book; not sure if it includes newborn though.

In the case that you set out, since it was practically adult already, I'd have just ignored any modifications and simply used the adult stats. Since it's an NPC, your players wouldn't know the difference anyway.

Here is a neat site for stats for DnD Children characters.

I see this often, but I'm pretty sure that's not how the rule works. That rule's for GMs designing/customizing monsters, and is intended to be applied before the monster is first introduced (or at the very least, while it's off-camera for a while). The monster doesn't suddenly get smarter/faster/wiser/tougher/dumber because he took a level of fighter after hanging out with the party, any more than he suddenly gains a bunch of gear - the same section says "A monster with class levels always possesses treasure equal to an NPC of a level equal to the monster's final CR".

On the other hand, representing growing up to be an adult by giving them a class level and applying the modifiers works, because story-wise the stat changes come from maturity rather than the class level.
