House Rules for Mystery Flesh Pit

MFPNP House Rules: Stress and XP Usage

Stress Track

Each character tracks Stress separately from physical damage (Might, Speed, Intellect pools). Stress represents mental and emotional strain from horror, fear, and trauma inside the Mystery Flesh Pit.

Characters have a Stress Track with 5 boxes:

Stress Level	Effect
1 Box Filled	Minor distraction; -1 penalty on rolls
2 Boxes Filled	Growing anxiety; -2 penalty, occasional hesitation
3 Boxes Filled	Panic sets in; -3 penalty, possible involuntary actions (freeze, flee)
4 Boxes Filled	Severe mental impairment; difficulty concentrating, confused actions
5 Boxes Filled	Breakdown; character may collapse or become incapacitated

Stress is gained from encounters with horrifying creatures, environmental hazards, traumatic events, failed rolls under pressure, and GM Intrusions.

Summary Table for Severe Mental Impairment

Effect	Mechanical Impact
Roll Penalty	-3 to all rolls
Action Delay	Acts last or delayed by 1 action turn
Confusion	Forgetting, mixing directions
Impaired Judgment	Cannot take risky/complex actions freely
Emotional Instability	Unpredictable fear, panic, aggression
Communication Difficulty	Slurred speech, muttering
Stress Resistance	Intellect defense roll at -3
Voluntary Stress Recovery	Not possible without outside help

Removing Stress

Characters can remove Stress boxes through the following methods:

• Rest and Narrative Downtime:

 Spending time away from immediate danger and engaging in calm activities allows characters to recover mental composure. Typically, characters can remove **1 Stress box per extended rest period** (e.g., a few hours of rest or safe downtime).

• Medical or Bio-Tech Treatment:

 Advanced medical care, bio-tech healing pods, or Anodyne Corporation treatments can accelerate Stress recovery. Such treatment may remove **1 or more Stress boxes**, depending on availability and quality.

• Player Intrusions (XP Spend):

 Players may spend 1 XP to remove a Stress box during gameplay, representing the character using inner resolve, quick coping mechanisms, or brief moments of calm.

• Narrative Resolution:

 Overcoming a major source of fear, confronting trauma, or receiving reassurance from NPCs or other PCs may allow the GM to grant Stress removal. This encourages roleplaying and story engagement.

• Special Abilities or Equipment:

 Some character types, descriptors, or Prototypes may provide unique ways to reduce Stress (e.g., meditation focus, calming implants, or drugs).

• Note:

Stress removal does **not** happen automatically and requires player attention or narrative justification. The GM should encourage pacing recovery moments to maintain tension and immersion.

XP Usage in Place of Grit

XP is the **only resource** used for stress management, player intrusions, rerolls, and character advancement.

Action	XP Cost / Gain	Notes
Accept GM Intrusion	Gain 2 XP	One for you / one for a friend.
Use Player Intrusion	Spend 1 XP	Introduce beneficial narrative changes
Spend XP to Reroll	Spend 1 XP	Reroll a roll.
Spend XP to Resist Stress	Spend 1 XP per stress box or major effect	GM discretion; mitigates stress penalties
Spend XP to Boost Roll to 18+	Spend 3 XP	Guarantees a roll of at least 18 on d20 for success
Character Advancement Options	Spend 10 XP each	Includes: 1) Increase stat Pools (+4 points total) 2) Increase an Edge (+1) 3) Increase Effort (+1) 4) Gain a Skill (trained) 5) Special option (armor cost reduction, +2 recovery, new ability)

Sources of XP

Players can gain XP from the following:

• Accepting GM Intrusions (+2 XP each)
• Overcoming dangerous encounters and stressful situations (GM awarded)
• Completing significant story milestones or objectives
• Exceptional roleplaying, especially related to managing stress and horror
• Surviving or resolving intense narrative moments inside the Pit

Additional Notes

• Players must balance spending XP for immediate survival benefits against long-term character growth.
• Stress recovery requires narrative downtime, medical aid, or character abilities.
• The GM uses Intrusions liberally to increase tension and award XP.
• This house rule replaces the default MFP stress and Grit systems with a unified XP-based mechanic.
