SLA BRP - Escalation Initiative (Advantage Die System)
Version: 1.0
Core Concept
Initiative is a single roll each round.
Operatives may gamble for speed using an Advantage Die. If they push too hard and lose composure, they freeze.
This system is designed to:
- Use a single roll per round
- Require no bookkeeping between rounds
- Work cleanly at table or in Foundry
- Integrate COOL as a psychological pressure mechanic
Round Procedure
Each round:
- Choose your approach:
- DEX (Reflex)
- INT (Read the Fight)
- Choose whether to take the Risk.
- Roll initiative.
Highest total acts first.
Normal Roll
Roll:
1D10 + chosen stat (DEX or INT)
Highest total acts first.
Risk Roll (Advantage Die)
Instead of a normal roll, you may roll:
2D10 + chosen stat
Keep the highest die.
However:
If either die shows a 1, you must immediately roll COOL.
COOL Test (When a 1 Is Rolled)
If no die shows 1:
- Act normally at your rolled initiative.
If a die shows 1:
- Immediately roll COOL.
COOL resolution:
Success:
- You act normally.
Failure:
- You freeze.
- You take no action this round.
- You may still Dodge or Parry.
Fumble:
- You catastrophically overcommit.
- You take no action this round.
- You cannot Dodge or Parry until after your initiative passes.
- GM may narrate a visible tactical error (stumble, twitch, hesitation, weapon slip).
Tie Breakers
If two characters have the same initiative total:
- Higher chosen stat wins.
- If still tied:
- The character who chose INT wins ties against DEX.
- If still tied:
- Actions are simultaneous.
Design Notes
- Rolling
2D10gives roughly a19%chance of triggering a COOL test. - This creates tension without heavy bookkeeping.
- Low COOL characters become increasingly vulnerable to freezing.
- This interacts naturally with Sanity erosion if COOL is penalized by low SAN.
- No tokens, no tracking, no recalculation mid-round.
- Every consequence resolves immediately.
Optional Differentiation (Optional Rule)
If the COOL roll succeeds after a Risk roll:
If you chose INT:
+10%to your first attack this round.
If you chose DEX:
- Gain
1mfree movement before your first action.
This adds flavor without adding tracking.
Foundry Implementation Notes
This system is simple to implement in Foundry because:
- It requires only one roll per round.
- No persistent state is required.
- No tracking of damage, tokens, or flags is necessary.
Suggested implementation approach:
- Create two initiative macros:
- A) Normal Roll
- B) Risk Roll
Normal Roll formula:
1d10 + @dex
or
1d10 + @int
Risk Roll formula:
2d10kh + @dex
or
2d10kh + @int
(kh = keep highest)
After the roll:
- If any die result = 1, prompt a COOL roll manually or via macro.
- Apply freeze effect narratively (no system state required unless desired).
Optional automation:
- Add a dialog checkbox: Risk?
- If checked, roll
2d10kh. - If either die result is
1, auto-prompt COOL roll.
No initiative reordering logic is required beyond setting initiative value.
Current system API hooks (first implementation pass)
In this system build, Escalation Initiative is available via:
game.brp.SLAEscalationInitiative.rollControlled({ approach: "dex", risk: false })game.brp.SLAEscalationInitiative.rollControlled({ approach: "int", risk: true })
Combat tracker single-combatant initiative rolls now prompt for:
- DEX or INT
- Risk on/off
Risk roll handling includes automatic COOL checks when any risk die shows 1.
Why This Works for 6 Players
- Everyone rolls once.
- Only risk-takers occasionally roll COOL.
- Freeze is immediate and resolved instantly.
- No end-of-round recalculation.
- No momentum tokens.
- No damage comparison.
It keeps combat moving.
It adds psychological risk.
It feels like SLA.
