Converting Creatures from Other Campaign Settings

[freyar]

Let's add tremorsense -- just seems good for a plant. Regular vulnerability to fire is good by me.

 

[Shade]

Updated.

A mature plant consists of a base about x feet long with several clumps of small-bladed leaves and lush, red berries. Thorny vines extend to 10 feet.

How large should the base be?

 

[freyar]

I earlier suggested 5 ft, but we could go 10 ft just to agree with the space (though space is really sort of an abstraction).

 

[Shade]

Let's go with 10 feet.

Time for the 4-HD version...

Do we want to increase Str and natural armor at various Hit Dice like the hydra? Anything else besides number of attacks and normal changes based on HD?

 

[freyar]

Why don't we start with just the normal minimal changes due to increased HD and see if we need to add anything to bump the CR? We should probably aim for CR+1 for each extra tentacle/HD.

 

[Shade]

Updated.

 

[freyar]

Ok, here are cumulative changes I'd suggest at each HD:
4HD - Str 16
5HD - natural armor +7, Dex 14
6HD - Str 18, Improved Initiative
7HD - natural armor +9
8HD - Str 20.

Does that seem sufficient?

 

[Shade]

Updated with those suggestions.

I think the CRs are still too high for the higher-HD versions. Compare to CR 6 tendriculous and shambling mound and CR 8 treant.

Edit: On second thought, the high number of attacks (and potential blood drain) seems to give it enough damage output to possibly offset the other abilities.

 

[freyar]

Yeah, I'm on the fence about the CRs, too. Anyone else have an idea?

 

[Shade]

Same guy chiming in again, but I compared to the hydra and they don't gain much more beyond an additional attack at each increased CR.
