d100 Weird Powers, or Why McDowell's OSR Discord is the Best

So... I needed some little powers for a project I'm working on. I decided to turn to the OSR Discord for help... A flurry of creativity later, and now we have this monstrosity!

DERELICT DESERTED DREADNOUGHTS

Image Source

(Third in the series after OUTLAWS and WIZARDS.)

They are living relics lost in time. You might see the silhouette of one in the distance, marching across the vast unknown for a cryptic purpose, or built into the side of a mountain. They carve tracts through the present according to the whims of the past. If you find one, will you be able to turn it to your side, through guile, mechanical expertise, or hacking skills? Or will it merely tread you into the dust like the footnote to history that you know you are?
Their programming is artful but never perfect. Over time, eRrOrS iN tHeiR CoDe MaY oCcuR.

This is now part of a series of generators!

Glog Class: SCAR-SPEAKER

Certain tribes at the edge of the Blasted Lands believe that every wound is a living portal to a spirit world made of flesh and bone that resides within all living beings. They alone understand the truth that those foolish practitioners of “scientific medicine” are blind to: the moment when flesh parts, the moment when blood seeps, the moments where in all knits anew, these moments are all alive in time just as we are. After all, scars are not made, they are born.
    

You can speak with scars. Most scars are torpid and extremely bored because nobody acknowledges their sentience. If you speak to one, it will animate and answer in a tiny voice. It may be (1d3) 1: mischievous, 2: stupid, or 3: helpful. This process is extremely unsettling for the person bearing the scar.
   

Starts with: a painful-and-intricate mutilation blade, a loincloth, and a Really Cool Scar (see table).
   

A Scar Tissue, Dispel Wound 

B Ritual Mutilation, Invoke Wound

C Rites of Scarring, Wound Possession

D One with the Spirits
   

SCAR TISSUE: When not wearing armor, you get +1 defense for each Really Cool Scar or Really Ugly Scar you have, to a maximum of +3.
 

DISPEL WOUND: Once per day, you can remove all fatal wounds from a target, then test your WIS. If you fail, you’ve offended the Wound Spirits, who give them a Really Ugly Scar (-1 to disposition rolls) before leaving.
 

INVOKE WOUND: Once per day, you can spend an action to call out to a the Spirit of a Wound that the target had suffered sometime in their life, and have that Wound open anew. Roll a d6 that increases in die size for each template of Scar-Speaker you have. The target takes that much damage, and if you rolled the max result for that die, the target rolls on the Death and Dismemberment table.
 

RITUAL MUTILATION: You can spend a minute to roll a d4 and take that much damage to regain the use of a once-per-day ability. If you roll a 4, you went overboard: roll again. If you roll a 4 again, gain a Really Cool Scar.
 

RITES OF SCARRING: You may spend a day preparing a ritual though which you can summon a friendly Scar-Spirit to inhabit the permanent injury of an ally. This ritual requires multiple meaningful components and an RP ceremony. At ceremony’s end, make a WIS check. If you succeed, the target gains a Really Cool Scar.
 

WOUND POSSESSION: Once per day, you can spend an action to send a Wound Spirit to possess the wound of an enemy, holding them in place with sheer pain. They must make a save or be paralyzed for 1d6 rounds. As an action, you may give the Wound Spirit a one word command, and if the target fails a save, the spirit will try to twist the possessed body to fulfill that command.
 

ONE WITH THE SPIRITS: You can enter a trance where you become a living conduit between the material world and the spirit realm, and every significant wound you take is inhabited by a friendly Wound-Spirit. The trance lasts 3d6 rounds. During the trance, you are not unconscious when you are at 0 hp or have fatal wounds, and having fatal wounds does not kill you until the trance ends. During the trance, you get +1 to all rolls for every fatal wound you currently have, and for every permanent major impairment from the D&D table that you have suffered in your lifetime. When the trance ends, the Wound-Spirits will attempt to carry you off to the spirit realm: save or die.

REALLY COOL SCARS

1 A patch of tough, leathery scab-tissue. Gives you +1 defense, but only if you’re not wearing armor.

2 This scar bears a grudge. Once per day, when you take the same type of damage that gave you the scar, you can halve the damage.

3 ‘It looks a little like a person! See, there’s the head, there’s the arms…’ This scar can see, hear, and speak. It can help you remember things or act as a lookout.

4 Receiving this scar has dulled your sensitivity to pain. Gives you 1 hp.

5 Makes you look like a complete badass. +1 to disposition rolls.

6 Looks like an arcane glyph. This scar can catch spells. If you succeed on a save vs a spell, roll a d6. On a 6, the spell has been caught in the scar and you can use it as if you spend the same amount of magic dice that the caster spent to cast it.

REALLY UGLY SCARS

1 People just can't stop staring at it. It grabs attention. You will be easily picked out from a crowd, but only for bad reasons.
2 It looks humiliating. In any conversation, it's only a matter of time before it will be the topic of discussion. Better make up a good cover story...
3 'It looks a little like a person... why are they giving me the finger?' This scar can see, hear, and speak, but it hates you. It will work against you when possible. Its disposition can be changed, though...
4 It's in the shape of an offensive symbol or design. Get ready to make some political enemies...
5 It always looks fresh... like it's going to open up again at any moment. This scar will wait until you are in a dangerous situation, then open anew, causing 2d6 damage.
6 Looks like an arcane glyph. This scar catches spells. But not in a good way. Each time a spell is cast near you, roll a d6. On a 6, the spell targets you instead. This only happens once per day.

Glog Class: SURGEON

Consensus is that the eccentric rogue surgeons who wander the Blasted Lands are worth their weight in gold. Still, tales abound of mad experiments done in the dead of night, producing monstrous perversions of the human form. None will say that to the Surgeons' faces, especially when its their wound that needs cleaning... but the doubts creep in when they're under the knife, staring up into that blank, inhuman mask...

You gain +1 to saves versus disease and poison for each Surgeon template you have.

Starts with: bone saw, scalpel, medical supplies kit, black cape, plague mask.

A Field Medic, Treat the Cause

B Triage, Diagnosis

C Surgery, Organ Harvester

D Experimental Cure, Transplant

FIELD MEDIC: You can make a straight INT test with advantage to remove a fatal wound from a dying ally, instead of an INT/2 test.
 

TREAT THE CAUSE: Whenever you heal a fatal wound, your next attack against the enemy that caused it deals double damage. If it kills them, it neatly severs a body part.
 

TRIAGE: Any round in which you spend an action doctoring a dying ally’s wounds does not count towards the 3-round death-timer.
 

DIAGNOSIS: By examining someone, you can tell the effect a condition or ailment is having on their bodily processes, even if you do not know what that condition or ailment is. By examining a corpse, you can discern how it died.
 

SURGERY: You can spend 6 hours to try and cure someone’s permanent injury. To do so, test your INT, then your patient tests their CON. If both are successful, you have cured the permanent injury. If only one is successful, you deal 1d6 damage to your patient. If both are unsuccessful, something has gone horribly wrong: your patient recieves a fatal wound and they roll on the death and dismemberment table. Add +1 to both tests for each of these elements you incorporate into the surgery: anaesthesia, sanitization, traction bench, blood transfusion.
 

ORGAN HARVESTER: For each corpse, you can spend one minute to harvest one organ or body part in pristine condition.
 

EXPERIMENTAL CURE: You may combine three reagents together into an Experimental Cure. When someone ingests the Experimental Cure, test your INT. If you succeed, they heal 1d6 hp, remove a disease, or stop being poisoned. If you fail, they take 1d6 damage (or the DM can make up a weird minor affliction for them to suffer). Someone can only be affected by an Experimental Cure once per day.
 

TRANSPLANT: Once per week, you can spend a full day to attempt to transplant one organ or body part from one creature to another. Do do so, perform Surgery on them (see SURGERY).
