Converting monsters from First Edition modules

Acid Squirt (Ex): A horgar can spit a stream of acid at an opponent or area. Treat this as a splash weapon. Thus, the horgar makes a ranged touch attack with a range increment of 10 feet and a maximum range of 20 feet. A direct hit deals 20d4 points of acid damage. Every creature within 5 feet of the point where the acid hits takes 5d4 points of acid damage from the splash.

perfect! I’m using that as-is.

Which post was that in again?

post #377 , which you responded to in a post a few pages back (#357).

and we’re just about done… need CR, maybe 20-ish?

Ahh, post numbers to the rescue. I'm fine with either the nausea or the usual environmental effect.

CR 20 seems reasonable. It is damn tough, but its deadliest abilities are easy to counter with protection from (or immunity to) acid effects.

To make things easier, here is the text in question:

The horgar smells like the super-heated acid that it secretes from between its rock plates, somewhat like ammonia. The gases make other creatures' eyes water and irritate their mouths and nasal passages.

Perhaps the acid information from the environment section of the DMG could be applied:

"Corrosive acids deals 1d6 points of damage per round of exposure except in the case of total immersion (such as into a vat of acid), which deals 10d6 points of damage per round. An attack with acid, such as from a hurled vial or a monster’s spittle, counts as a round of exposure."

"The fumes from most acids are inhaled poisons. Those who come close enough to a large body of acid to dunk a creature in it must make a DC 13 Fortitude save or take 1 point of Constitution damage. All such characters must make a second save 1 minute later or take another 1d4 points of Constitution damage."

"Creatures immune to acid’s caustic properties might still drown in it if they are totally immersed (see Drowning)."

so, perhaps for creatures in adjacent squares to a horgar or one of its acid pools, we can give a negative effect. We could add a paragraph like this to the Corrosive Slime description, or perhaps give it its own description:

The fumes from a horgar’s acid are inhaled poisons. Any creature that is adjacent to a horgar or one of the pools of acid it leaves behind must succeed on a DC X Fortitude save or take 1 point of Constitution damage. All such creatures must make a second save 1 minute later or take another 1d4 points of Constitution damage.

I think that should work. I'd recommend its own entry rather than tacked onto corrosive slime.

Yep, that’s pretty crowded anyway. ok, updating in homebrews; don’t see much more left beyond plugging in some values here and there.

For weight, it is twice as long as a delver, which is kinda similar in body shape. If we double the weight of a delver, we get 6 tons.

Heat DC (second paragraph) = 32.

Noxious Stench should be Con-based, DC 32.

A horgar’s mere touch deals 20d4 points of acid damage to organic creatures or objects. Against metallic creatures or objects, a horgar’s slime deals X points of damage, and against stony creatures (including earth elementals) or objects it deals X points of damage. The passage of a horgar through earth leaves pools of pure acid that form at the bottom of the tunnel. Any creatures touching these pools with bare flesh take 10d4 points of acid damage. The pools of acid evaporate in X rounds/hours.

The delver's formula is 2d6, 4d8, 8d10. This doesn't really follow any of the current size increase for damage tables I could find, but I think the following would work:

20d4, 20d8 vs. metallic, 40d10 vs. stone.

I have no idea for the acid duration.

 

[BOZ]

For duration of the acid pools, how about 1d3 days?

 

[Shade]

That should work.

 

[BOZ]

OK, updating… how’s this big fella look?

 

[Shade]

He looks like a slug made from black granite.

But seriously, I think he's finished.
