Doing the math to convert the LA levels into
real ones, makes say equivalent d5.7 hit dice,
or 1.3 skills per level, same with saves.
Easy enough, though mostly a tier 5 or 6 idea.
But it's not just a matter of how normally strong they are
but also how many options are left when the prog is done.
So like Carnivore's fave the Pixie is almost
Tier 0 on it's casting amazeballs,
BUT it's hd skills and saves are hideously dangerous.
That'd make it a fragile Tier 3 , yet could qualify for Nar Demonbinder easily.
Worth doing such an oddball hash ?
