PLASM

A plasm looks like a human- or giant sized skeleton made of elemental and ethereal matter. There are four types of plasm; one for each of elements of air, earth, fire, and water. A plasm is made of a combination of elemental material and ectoplasm (solid ether). It cannot safely exist on any plane except the Ethereal, or interplaner portal or wormhole, where it may sometimes be encountered.

---------------------------------------------------------------------------
PLASM, GREATER
Large elemental, chaotic neutral
---------------------------------------------------------------------------
Armour Class 17 (ethereal armor)
Hit Points 68 (8d10 + 24)
Speed 30 ft.
---------------------------------------------------------------------------
STR|DEX|CON|INT|WIS|CHA
20 (+5)|12 (+1)|17 (+3)|8 (-1)|10 (+0)|12 (+1)

---------------------------------------------------------------------------
Damage Resistances force
Damage Immunities poison, bludgeoning, piercing, and slashing from nonmagical weapons
Condition Immunities poisoned
Senses passive Perception 10
Languages -----
Challenge 6 (2,300 XP)
---------------------------------------------------------------------------

Ethereal Dependant. At the start of each of the plasm's turns, if it is not on the Ethereal Plane or in an inter-planar portal, it takes 4 (1d10) force damage and its hit point maximum is reduced by an amount equal to the force damage taken.

Elemental Absorption. Whenever the plasm is subjected to the following damage - thunder damage against an air plasm; bludgeoning, piercing, or slashing damage against an earth plasm; fire damage against a fire plasm; acid damage against a water plasm - it takes no damage. Instead, its hit point maximum is increased, and hit points are regained, by an amount equal to the damage.

---------------------------------------------------------------------------
ACTIONS

Multiattack. The plasm makes two claw attacks.

Claws. Melee Weapon Attack: +8 to hit, range ft., one target.
Hit: 19 (4d6 + 5) slashing damage.

Ether-Elemental Cloud (Recharge 6). The plasm creates a 15-foot-radius sphere of ether-elemental cloud based on its type, centered on the plasm. Each creature within the cloud takes 34 (6d10) force damage, including the plasm, although it has resistance to force damage. Afterward, when a creature enters the cloud's area for the first time on a turn or start's its turn there, that creature must make a DC 15 Constitution saving throw, taking 16 (3d10) force damage on a failed save, or half that amount if successful. The cloud is composed of the element matching the plasm's type and lasts for 3 rounds. The cloud does not move and its area is lightly obscured. The plasm normally reserves this action for when it wants to flee.


Image

[Design Note: The Greater Plasm should actually have been a CR 5 creater if I went strictly by my conversion guide, but I just couldn't get it down the that level and not feel too close to the lesser version. One or more of its HD or strength or other aspect would be too close to the lesser's that it didn't feel right. So we end up with a (possibly) slightly more powerful version in 5E than in the RC.]

I'd also noticed that about the Undead CR gap between 5 - 13! I've picked up several homebrew undead that also fit in that gap, and yours are a great addition!

Thank you for your hard work! :mrgreen:

It sure is quite the gap, but more will appear soon to help fill it in.

And thanks for the comment!

REVENER
This monster appears as a human figure with skeletal hands and a skull head with flowing, white hair. A revener prowls dark, underground caverns and dust-filled tombs and crypts.

---------------------------------------------------------------------------
REVENER
Medium monstrosity, chaotic evil
---------------------------------------------------------------------------
Armour Class 17 (natural armour)
Hit Points 71 (11d8 + 22)
Speed 40 ft.
---------------------------------------------------------------------------
STR|DEX|CON|INT|WIS|CHA
13 (+1)|16 (+3)|14 (+2)|10 (+0)|11 (+0)|12 (+1)

---------------------------------------------------------------------------
Saving Throws Wis +3, Cha +4
Damage Resistances bludgeoning, piercing, and slashing from nonmagical weapons
Senses darkvision 120 ft., passive Perception 10
Languages -----
Challenge 5 (1,800 XP)
---------------------------------------------------------------------------
ACTIONS
Multiattack. The revener makes two claw attacks.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature.
Hit: 6 (1d6 + 3) slashing damage, plus 10 (3d6) psychic damage. The creature loses any sense of taste it may have had and must make a DC 16 Intelligence saving throw. On a failed save, the creature is deafened. If the save failed by 3 or more, it is also blinded. If the save failed by 5 or more, the creature is also stunned. Conditions gained from the revener last for one minute. The creature can repeat the saving throw at the end of each of its turns, ending one condition on itself on a success.


Image

[Design notes: I departed from the RC version moreso here than I tend to do. The original is basically a "screw the PCs" monster as it removes senses, not damages them. While I think the aftermath could be a great roleplay opportunity, the monster really doesn't threaten them in any real way.

Its hps and xp from the RC suggested a CR 5 creature in 5E, and I really struggled to get there without creating a decent damaging component to it. The idea I came up with (from the sparce info in the RC) is that it is essentially a mind effecting creature, manifesting in 5E as pyschic damage and its ability to drain senses from creatures. (If I was a creature that could not harm anyone else, only remove their senses one by one, I wouldn't be attacking anything!)

Finally, the RC version's sense-draining ability is much longer lasting and that doesn't gel well with the 5E handling of conditions like that - it generally provides recurring saving throw attempts. To increase the potency I gave it the ability to inflict several conditions at once, and only one can be 'cured' each round. This was a tough one to convert to 5E's structure but I'm pretty happy with it actually.

What a fantastic thread! I am thinking about running a scenario I pencilled out for B/X and now I don't have to fake the giant gecko and ferret! Thanks so much for these.... will you compile them for the DMs Guild someday? I see in your sig you've published before :)

Thanks! And I'm very happy to see that some of these will be useful.

However, I don't have a sig and I've never published on DM's Guild before. :P

I don't see myself collecting these into any single work; mainly because it's outside my knowedge and ability so far. Plus, these are conversions of someone else's work (i.e. TSR) and don't have much of the flavor attached. It's targetted mainly for those running adventures linked to BECMI D&D in fifth edition and/or in the Mystara setting, but can obviously be used by anyone running 5E.

And since I'm posting anyway, I'll be away for the rest of the week at a conference, so I won't be able to work on any more creatures (Rhagodessa is next) until after I get back. ;(

No worries! I really don't think I could do a compilation, but you never know if someone else were to do it.

RHAGODESSA
A rhagodessa is a giant spiderlike carnivore, about the size of a small horse. It has an oversized head and mandibles colored yellow, and a dark brown thorax. It has five pairs of legs; the front pair end in suckers which help the creature grasp its prey.

Rhagodessae are nocturnal carnivores, hunting only in the dark. They are normally found in caves, and can climb walls.

ROBBER FLY
A robber fly is a 3 foot long giant fly with black and yellow stripes. From a distance, robber flies look like giant bees. They are carnivores, and may attack adventurers. However, they prefer giant bees and wasps as food, and are immune to their poisons.

Robber flies are patient hunters - they often hide in shadows and wait to surprise prey.

Nice work Hugin!

I'd love to use Pteradactyl riders more! They fit well in the Hollow World, in Blackmoor, on the Isle of Dawn and elsewhere.

That reminds me that there is also the skinwing from the Shadow Elves Gaz, but it isn't in the RC so I'm not converting it... yet.

I actually skipped over doing the pterosaurs thinking there wasn't any need to do size variations of a creature already in the 5E MM. But then my OCD kicked in and I had to go back and do them.

Image

[Design Note: While the large roc maps to a CR 4 creature in the RC, I had to make it a CR 5 creature in 5E in order to have its attack progressions between the three sizes flow nicely; i.e. the "giant" roc in the 5E MM has attacks with 4 dice, and the ganeral method of adjusting attack when size changes is to multiply the number of dice. So if a guargantuan size creature's beak does 4 dice damage, the huge sized creature's beak does 3 dice, large sized does 2, and medium sized 1. Thus, I wanted the "huge" sized roc, known as the large roc in the RC, to have 3 dice damage, and therefore it had to be 5 CR.]


ROC, GIANT
