Re: Bestiary builds, what do monsters do with experience?
Essentially, yeah. Don't get too caught up in using points to determine power levels, though. The points determine how effective a character/animal/monster is on a campaign-wide scale. Most of the time, though, you only use monsters for combat, and if they've spent most of their points on combat abilities, they will totally pwn PCs that spent a lot of points on non-combat stuff, assuming they have equal point values.
For combat purposes, it's best to compare OCVs, DCVs, SPD scores, damage-dealing ability, and defenses.
