The Call of Crimson

 

A few of my gamer buds online have been asking me about my d20 hack of the Call of Cthulhu RPG...

Well, here you go!  Do this, and you'll be playing a rules-light investigative horror RPG worthy of H.P. Lovecraft himself.

• Every PC gets 10 HP per level (if this is a one-shot with medium to high challenge, make the PCs 3rd level).  You're unconscious at zero HP and lower, up to your level in negative numbers.  Go beyond that, and you're dead.
• AC for normal, unarmored humans is 10.
• Every PC gets 1 point of luck per level that can be spent throughout the scenario.  Spending a point of luck allows that PC to re-roll his failed die result.
• Choose an individual special skill that has nothing to do with your character concept.
• When attempting an action, favorable circumstances yield Advantage (roll twice, take higher result) while unfavorable circumstances yield Disadvantage (roll twice, take lower result).
• The target # for skill checks is 15 (assistance yields Advantage).
• When attempting an action, roll a d20.  If your character would have that skill (you may have to justify it with a recollection from your character's past), add your level to the roll.  
• Sanity - if a person sees something unbelievably shocking or just plain scary, make a saving throw (your save is 20 - character's level).  Each failed save means the PCs gets worse...  1st failed save means character is visibly shaken; Disadvantage on all rolls for the next hour.  2nd failed save means he's developed a lasting phobia (choose as appropriate), as well as, some kind of off-putting mannerism or tic.  3rd failure means permanent insanity and unable to function as an investigator.

Ok, that's all I've got so far.  If something else comes up during play, I'll add it to the list.

Again, nothing revolutionary.  Just my attempt to make Call of Cthulhu play like Advanced Crimson Dragon Slayer.
