Converting monsters from Second Edition Monstrous Compendiums

It looks like we have ranges 7-10 HD for young and 11-14 HD for elder, so let's go with 10HD for the "standard" sea wyrm and 14HD for the elder sea wyrm, if everyone agrees. We can let the standard one advance to 13 HD, and the elder can advance how we like.

I like it. Any objections?

 

[demiurge1138]

I like it too.

Added to Homebrews.

Let's go with aquatic and amphibious SQ, I think. Then it looks like we're done with special abilities already.

2d8+Str constrict?

The original AC would imply +4 natural, but that seems a little low. +10 or +12 or so?

 

[Shade]

If attacking a ship, every 10 points of constriction damage acts as 1 hull point against the vessel. If the ship is smaller than the sea wyrm, the wyrm can completely encircle the vessel, roll it over, and drag it beneath the waves. Because of this, they are greatly feared by fishermen and others who usually have smaller boats.

Downsize this ability from the sea drake?

Constrict Ship (Ex): Instead of crushing a ship with its tail, a sea drake can wrap its serpentine body around all but the largest ships and crush them or drag them below the waves automatically. This can be done to a rowboath (1 round), keelboats (3 rounds), longships (5 rounds), and sailing ships (10 rounds). Warships and galleys are too large for a sea drake to affect in this way.

 

[freyar]

Sure (is there some other similar ability we've used elsewhere, too?). I'm guessing the Large ones can only get rowboats and maybe keelboats. 3 and 5 rounds for those?

Dragon turtle has this...

Capsize (Ex): A submerged dragon turtle that surfaces under a boat or ship less than 20 feet long capsizes the vessel 95% of the time. It has a 50% chance to capsize a vessel from 20 to 60 feet long and a 20% chance to capsize one over 60 feet long.

We gave the sea titan a bunch of ship-smashin' abilities.

 

[demiurge1138]

I prefer the sea drake's ability as a model, rather than capsize.

 

[Shade]

Yeah, it seems to be the best fit.

Taking freyar's suggestions above, revising...

Constrict Ship (Ex): A sea wyrm can wrap its serpentine body around smaller boats and crush them or drag them below the waves automatically. This can be done to a rowboat (3 rounds) or keelboats (5 rounds). Other seafaring vessels are too large for a sea wyrm to affect in this way.
