One-Off Spells (Slave Fatigue Only)

No one-off spells added yet.

These spells add fatigue directly to the slave pool. Uses global Magic Scale & Num Slaves. Master Encumbrance is not applied. The "Off-Path" checkbox for one-off spells means slaves are considered path 0 for calculating their fatigue multiplier for that specific spell.

Documentation & How It Works

Purpose:

This tool simulates fatigue and HP loss for a communion over time, considering main spellcasting, one-off spells, and an optional recurring Battlefield Rigor Mortis effect.

How to Use (Inputs):

Spell Settings (Main Communion Spell):

  • Base Fatigue: Fatigue cost of the spell before modifications.
  • Path Req: Required magic path level to cast the spell.
  • Encumbrance (Master): Master's encumbrance, adding to fatigue.
  • Magic Scale: Province magic scale (-3 to +3), affects fatigue costs.

Caster/Slave Settings (Main Communion Path):

  • Caster Level: Master's magic level in the spell's path (for main communion spell).
  • Slave Level: Slave's magic level in the path (for main communion spell, and for one-off spells if "Off-Path" is not checked for them).
  • Number of Slaves: Total communion slaves.
  • Number of Masters: Total communion masters casting the main spell.
  • Communion MR: Magic Resistance for masters and slaves against Rigor Mortis.

Fatigue/HP Settings:

  • Initial Slave Fat: Starting fatigue of the slave pool.
  • Initial Master Fat: Starting fatigue of each master.
  • Slave HP: Starting HP of the slave pool.
  • Extra Slave Reinvig/Turn: Additional fatigue recovery per turn for slaves.
  • Extra Master Reinvig/Turn: Additional fatigue recovery per turn for masters.
  • Healing (HP)/Turn: HP regeneration per turn for slaves.

Simulation & Battlefield Settings:

  • Turns: Number of turns to simulate (1–10000).
  • Relief spell active: If checked, applies fatigue recovery each turn.
  • Enable Battlefield Rigor Mortis?: Check to activate the Rigor Mortis effect.
    • Rigor Extra Pen: Additional penetration bonus for Rigor Mortis.

One-Off Spells:

  • Turn: Turn the spell is cast.
  • Base Fat: Base fatigue cost of the spell.
  • Path Req: Required path level for this specific spell.
  • Caster Lvl: Caster’s level in the path for this specific spell.
  • Off-Path: If checked, slaves are considered path level 0 for calculating their fatigue multiplier for this specific spell. If unchecked, the global "Slave Level" is used.

Mechanics Modeled (Attempting to match spreadsheet and game definitions):

Single Exploding Die (openD6_dom): A d6 roll. If '6', counts as 5 and re-rolls, adding new result. Repeats for more '6's.

Dominions Random Number (DRN): As per game definition: openD6_dom() + openD6_dom(). Calculated by calculate_game_DRN().

Communion Master Level (CM Level): FLOOR(LOG2(Number_of_Slaves)) + Caster_Level.

Master Fatigue Component (MFC_base): (Base_Spell_Fatigue / (1 + MAX(0, CM_Level - Spell_Path_Req))) * (1 - 0.1 * Magic_Scale).

Master Fatigue Cost (per main spell): Master_Final_Cost = (MFC_base + Master_Encumbrance) / (1 + Number_of_Slaves).

Slave Fatigue Multiplier: Based on Caster Level (CL) vs Slave Level (SL):

  • If SL == 0: If CL == 1, then 2x; Else, 4x.
  • Else (SL > 0): If FLOOR(CL / 2) > SL, then 4x; Else if CL > SL, then 2x; Else if CL == SL, then 1x; Else (CL < SL), then 0.5x.

Slave Fatigue Cost (per main spell): Master_Final_Cost * Slave_Fatigue_Multiplier.

One-Off Spell Slave Fatigue: (MFC_base_one_off / (1 + Number_of_Slaves)) * Slave_Fatigue_Multiplier_one_off. (No master encumbrance).

Fatigue Damage (when fatigue reaches or exceeds 200): For main/one-off spells: 1 + FLOOR(Fatigue_Cost_that_Pushed_to_200 / 50). Applied for each event causing fatigue >= 200. For Rigor Mortis: 1 HP damage if its fatigue addition causes slave fatigue >= 200.

The simulation proceeds turn by turn (order of operations):

  1. Battlefield Rigor Mortis (if enabled): Pulses occur. For each hit on slaves, fatigue applied. If slave fatigue reaches/exceeds 200 due to this pulse, 1 HP damage taken. Masters also take fatigue if hit.
  2. One-Off Spells: For each, fatigue applied to slaves. If slave fatigue reaches/exceeds 200 due to this spell, calculated HP damage taken.
  3. Main Communion Spell Casting: Each active master casts. Master takes fatigue. For each master's cast, slave fatigue is added. If slave fatigue reaches/exceeds 200 due to *this specific master's contribution*, calculated HP damage taken.
  4. Relief Spell (if active): Recovers max(0, 1 + calculate_game_DRN() - calculate_game_DRN()) fatigue.
  5. Natural Fatigue Recovery: Standard recovery + Extra Reinvig.
  6. HP Regeneration: Slaves heal HP.
