They are roughly equal in combat against the core 4-PC party. The NPC accomplishes this by burning through 1000's of GP in dedicated NPC gear value of potions, poisons and such while the monster just uses it's innate abilities and possibly a piece of treasure if it was lucky enough to have something it could use and figure out.. In that way they are relatively the same Challenge Rating.
Actually, no. A monster just using its innate abilities like, say, an ettercap, has only a Challenge Rating of 3. Meanwhile, a 9th level character with gear is supposedly a Challenge Rating of 9 (I'd argue an 8 or 7, but whatever).
A 5 HD, +4 LA ettercap comes in at an ECL of 9. That number presumes it will have the gold for a 9th level character.
And even without either the ettercap or PC having but the barest amount of gear - let's say, a greatsword for a fighting type or a spell component pouch/holy symbol for a spellcaster - I think it's fairly clear the two aren't remotely balanced. Against each other, the 9th level PC will almost certainly decimate the ettercap. Against a party of 4-PC's, the 9th level PC is the greater all-around threat. Hold person will give an unequipped 9th level fighter a bad day, but presuming a party of four 3rd level PC's to match up with the CR 3 ettercap, they won't have many, if any, such spells memorized. About 25-50 gold of equipment and a 9th level PC will roast a party of four 3rd level PC's. Whereas the ettercap is a fair challenge.
There is nothing "relatively the same."
An ettercap, ungenerously LA’ed I’ll admit, has an unlimited supply of poison as the rules are set up. That has to be accounted for. Nothing even prevents it from supplying it’s whole party with a toxin that would be worth at least a few hundred GP a dose.
Nothing? Let's start with the fact that the rules say zip about an ettercap just spitting poison all over an allies weapons, nothing about it lasting past a round, or anything. All of that is completely under the adjudication of the DM. And the default assumption by the rules is that the ettercap can't just share its poison - in the same fashion that poison isn't listed as a possible treasure from the ettercap, in the same fashion a rogue can't just "share" his Evasion and so on and so forth. Some things make more sense to share (poison over evasion), but the rules don't assume such sharing.
Yeah, an ettercap might reasonably be able to share some poison. But that's completely at the DM's discretion. And any player that tries using the "If the rules don't specifically disallow it, it must be allowed" deserves a good smack in the mouth.
Might as well say you're casting fireball so, when all the air rushes in to the place where fire just consumed it, it knocks the monster over the edge of the cliff it was standing on or similar such silliness. No - the rules don't say you can do that, so the presumed state is you can't. And anything beyond that - such as being able to share poison - is completely and fully at the DM's discretion. Accounting for possible "extras" isn't in Level Adjustments purview.
