Converting Greyhawk monsters

Well, you get a Fort save for each one. Maybe we could base the numbers on the reverse of Swallow Whole. So that would be 2 for a Small victim, 4 for Medium, etc. How's that?

That solution sounds good.

That'd work!

So, doubling each time?

Only a single yphoz can attach itself to creature up to Tiny size, up to 2 yphozs can attach to a Small creature, up to 4 for a Medium creature, 8 for Large creature, 16 for a Huge creature, 32 for a Gargantuan creature and 64 for a Colossal creature.

That works for me!

Updated.

Skills: Climb +7, Swim +7, 5 ranks
Spot?

Feats: 1
Weapon Focus (bite)? If it can't hit, it can't attach and do any of its other cool stuff.

Challenge Rating: 1?

Advancement: 3-4 HD (Tiny); 5-6 HD (Small)?

Did we deal with this?

They are composed of a gelatinous substance that matches the color of the water in which they live, ranging from black to varying shades of brown to varying shades of green or yellow. They may even be colorless. This feature makes them almost impossible to detect in their home pool (PCs in yphoz-infested water rolling 4 or less on 1d6 are surprised).

Or this?

When a yphoz is in water and another creature swims within 20', the disturbance of the water will alert the yphoz to the presence of a potential meal.

Blindsense 20 feet in water only?

Good, stick it in the Attach description and I think its special abilities are pretty well sorted.

Thoughts on the rest (see 2 posts up)?

Sorry, I hopscotched your post.

I'd prefer 3 in Listen and 2 in Spot.

Suits me.

They look more like a CR 1/2 to me, since they're roughly equal to a Stirge as a threat.

Advancement: 3-4 HD (Tiny); 5-6 HD (Small)?

I prefer 3 HD (Tiny); 4-6 HD (Small).

I did wonder about making them "—" like a Stirge, but considering the original describes old yphoz's as growing much bigger than young 'uns I think an Advancement is in order.

Give them a hefty (+12?) Hide bonus when submerged in swamp-water.

Yes, that's what I'd go for too.

A yphoz has one more HD and the numbing poison, which I think easily pushes them to CR 1.

We still need a duration for the numbing poison, BTW.

The effects of numbness last as long as the yphoz is attached and x rounds thereafter.

Yes, but Stirges' blood drain does more than twice the average damage, and Stirges can fly. A Yphoz is so slow that they're easily outmanoeuvered, a not inconsiderable weakness.

Plus, Stirges have much better AC than a Yphoz.

Although that brings up an interesting point, should we have a "Blood Drain limit" for the Yphoz? How many Con points worth of blood would fill one up?

1d6 rounds?

 

[Shade]

I'm still standing by CR 1. They are swift in the water, can wallcrawl to get the drop on victims, and only need a single hit to really mess up a 1st-level character.

1d6 rounds and a blood drain "fill limit" appeal. Stirges "fill up" at 4 points drained...maybe 6 points for a yphoz since they are bit more amorphous?
