Seems more reasonable to go for 50, especially given how you've described him upthread. I don't really see why he SHOULD be any higher (keeping in mind I haven't seen the movie.)
Is 3900 hp OK for that CR?
If we could just get his AC to like 70 or so, I think Clover would be in pretty good shape.
(Of course, a caster would likely tear it apart in one round easily, that's just a failing of this type of monster, really. Not much you can do about it while it's still "Cloverfield". If it can't stand up to a typical 50th level party without giving it abilites that don't mesh with it's flavor...maybe we should bump it down until it comes out even.)
Maybe we should raise both its Dex and natural armor, then.
If it's an Aberration, we can give it SR. SR 62 (12 + CR) sound good?
Belzamus said:I still postulate that DR should go up way higher at immortal levels. I mean, maybe it makes sense for Clover to have 50, but think of a Greater God. He's likely to take upwards of 500 damage a hit in melee, yet has a DR of 40. I don't see why 200 would be out of place, nor for Fast Healing/Regeneration. At least make it relevant to the fight. It's a nonability at that level. DR 40 is decent at level 20. 400 wouldn't really be out of place for a resilient Greater God, I don't think. And then allowing it to be multiplied by Sidereal/Eternal HP modifiers would help it keep up there as well. (An Old One, for example, would have DR 4,800/--.) Sounds closer to me.
Hey Belzamus dude!
I don't think that will actually help the problem, simply paper over a crack and create a new problem in the process.
I mean if you allow some sort of DR multipliers, then the PCs, NPCs and monsters without Power Attack Multiplication totally get the shaft. Which means you probably need to instigate both as standard, which then cancels each other out defeating the point of having them in the first place.
Only problem is, the CRs in the MM are wrong. Going by UK's CRs, a T Rex is CR 13. In point of fact, a blue whale is a hell of a lot bigger (just over 100 feet long and up to 190 tons, according to Wikipedia) - firmly in the Colossal bracket. If you want to go with dinosaurs, there are a few that are proposed (I say that because they're working off incomplete skeletons) to be even bigger.In the MM, a Killer Whale is CR5, Brown and Polar Bears and Tigers are all CR4. Tyrannosaurus is CR8, so I'd say that (going by the official animal stats) CR10 ought to be the absolute max for any natural our-Earth creature.
I agree. Going by this system I adapted from v5 (which, IIRC, I posted here and everyone pooh-poohed), a blue whale would have around 25 HD.A creature's HD shouldn't go up with size quite that easily. That's the equivalent of an increase in HD proportional to the increase in linear dimension (both double each size category). The MM/SRD porpoise is 4 to 6 feet long and has 2 HD. A whale 100 feet long, x20 times longer, shouldn't really have 40 HD - realistically, the biggest whales probably shouldn't have more than 15 HD, probably less; they really were fairly easy to kill. A 40 HD whale would make whaling nearly impossible.
All except the bear - I'd put it around 130 HD (guesstimating, since I didn't extend the tables to Macro-Dim).a Colossal lion = 26-27 HD
a Gargantuan rhinoceros = 24-25 HD
a Colossal rhinoceros = 42-43 HD
a Gargantuan elephant = 19-20 HD
a Colossal elephant = 33-34 HD
a Titanic elephant = 58-59 HD
a Macro-Diminutive brown bear = 172-173 HD
...which all sound reasonable.
