I recently started running a new campaign and i've got into a problem with one of the characters.
I know the rule about using monsters as PC, that says that every 3 levels you gain an additional level, a number of times that equals half the monster base cr rounded down.
But is that the same if the additional CR is gained not for using a monster, but for stacking CR with race and templates?
For example with a +1CR Race and a +2 CR template, would he be allowed to gain the additional level when the group is between level 6th and 7th? ( counting that the with that cr the pc's started at level 4, 6th to 7th level is between 2nd and 3rd level gained by the group if i understood correctly the rules).
I'm leaning toward not letting the CR gained by race and template be lowered, since the rules says it's that way because racial HD are less valuable than class levels in the long run, but those two don't add HD, just a lot of other things, but i was wondering what the general consensus is in this matter if there's one.
Thanks
