Converting prehistoric animals

[demiurge1138]

Everything looks good. I like the idea of giving them Hold Breath.

Updated.

Rather than "hold breath", how's this?

Partially Amphibious (Ex): A mastodonsaurus can survive for a number of rounds equal to x times its Constitution score out of water. After that, it risks drowning. For a typical mastodonsaurus, this is x rounds, or x minutes.

Edit: On second thought, should we just adapt this?

Water Dependent (Ex): Sahuagin can survive out of the water for 1 hour per 2 points of Constitution (after that, refer to the drowning rules on page 304 of the Dungeon Master’s Guide).

CR 4?

Advancement: 6-9 HD (Large), 11-15 HD (Huge)?

A mastodonsaurus is 12 to 15 feet long, weighing around x pounds.

So it comes down to hours vs minutes, really. I'm thinking go with Water Dependent. 800-1000 lb? The rest seems good.

 

[demiurge1138]

Water dependancy looks good to me.

Updated. Complete?

 

[freyar]

Looks done.

Ready for the Platyhystrix?

It looks like it should be Small ("less than a meter").

Downsizing eryops would yield...

Str 13, Dex 12, Con 15, Int 1, Wis 11, Cha 5

Sound OK? 1 Hit Die?

 

[freyar]

That all sounds good.

Perhaps we can give it some kind of thermal tolerance thanks to that "sail."

 

[Shade]

Added to Homebrews (with some placeholders from eryops).

Should we retain improved grab/swallow whole (downsized, of course)?

How about the Hide bonuses in water? I can't seem to locate any information on their tactics.

 

[demiurge1138]

Bonus to saves vs. temperature extremes is good. I think we should ditch improved grab and swallow whole, and the Hide bonus in water. They appear to have been predominately terrestrial--we might not even want them to get a swim speed.
