Converting "Real World" Animals and Vermin

[Shade]

This thread continues BOZ's idea of “cooperative conversions”, converting a series of monsters from similar sources. For this thread, we will be focusing on animals and vermin from various D&D sources that either exist in the real world, are giant versions thereof, or are slight variants of real world creatures. This does not cover dinosaurs or prehistoric animals, as they are covered in this thread.

What I will do is first post the creature’s original stats and flavor text. Then, I will post a basic outline of the things I think it needs, and then I will give you an opportunity to suggest stats and ideas on how powers and abilities should work. Then, I will add more to it and we will continue to discuss it until I feel it’s done and time to move on to the next. As we work on these creatures, they will be posted in this thread, and after 10 conversions are complete they will be added to the Creature Catalog. You may comment on monsters already finished, of course.

The following is a list of prehistoric animals from various that haven’t yet appeared in official WotC products, the Tome of Horrors, or the Creature Catalog. You may feel free to make suggestions, but ultimately I will pick what to convert and when. If I’m missing any monsters from this list or if any of these have appeared elsewhere already, feel free to inform me. (With thanks to Echohawk for the lists).

I can't pass up the opportunity to update something from the 1E MMII.

Crane, Giant
Freq: Rare
# Appearing: 1-20

Giant cranes are found in the same habitats as are ordinary cranes, herons, bitterns, and similar wading birds. They hunt large fish in marshes and swamps, along the banks of watercourses, or on lake verges. Although generally nonaggressive, giant cranes are protective of their mates, young, and nesting areas. If more than 10 are encountered, it is 50% likely that each additional bird will be an immature specimen. If 20 are encountered, there is a 50% chance that they are part of a great flock of 31-50 (1d20+30). From 3-12 of the flock will be half-grown fledgelings.

A large, wading waterfowl, the crane is a stately bird which perches
upon long legs. They are known for their loud, trumpeting call –
which can be heard for miles in any direction.

There's also the ibis from Races of Faerun to work from.

Advancing an ibis from Tiny to Medium and 3 HD results in the following:

Combat

Wading (Ex): Although it does not have a swim speed, a giant crane suffers no movement penalty when walking through water less deep than the length of its legs.

Skills: Giant cranes receive a +4 racial bonus on Spot checks.

 

[Shade]

Giant eagles, giant owls, and terror birds all have Dex 17, so we should probably bump the giant crane's to around that score.

You've got the giant badger and beaver listed twice.

You've got the giant badger and beaver listed twice.

They're really, really gigantic.

I'll fix it.

 

[Mortis]

They're really, really gigantic.

Titanic even.

I think advancing the ibis works - you get get rid of weapon finesse as it's Str is now greater than it's Dex. It's a bonus feat so it doesn't actually affect anything.

How about Stealthy as the second feat. I can see the crane quietly stalking its prey before lunging with its beak.

I'm slightly concerned with the wading quality - we should probably state either how long the legs are or the depth of water the crane can wade through.

Mortis

 

[Shade]

Note that I proposed a Dex boost to 17, so its Dex would once again be better than its Str, making Weapon Finesse useful once more.

Stealthy sounds fine.

I share your concerns about the wading ability. I've found that whooping cranes are 5 feet tall, so they are probably the best normal crane to build from. Unfortunately, I've Googled like mad and can't find any indication of leg length other than that they are long. Maybe we can just go with "half their height"?

I guess that should do.
