Dice — Cthulhu: Death May Die
| Standard dice | hit, miss and tentacle faces |
|---|---|
| Tentacle | negative result, usually tied to madness |
| Bonus dice | added by abilities and equipment |
| Elder sign | special result used by certain abilities |
More dice also means more risk
Death May Die inverts the usual logic of stacking dice. Abilities and equipment let you roll more dice, which raises the chance of hitting — but also raises the chance of rolling a tentacle, which pushes the investigator closer to madness.
That makes the question of how many dice to roll a real choice rather than an obvious optimisation. Seeing individual results separated from the total, as this tool shows, helps make the cost of each extra die visible.
Madness is not purely a penalty: the game uses the escalation as part of its narrative and some abilities depend on it. Even so, crossing the threshold has a hard consequence, which is what the tentacle count tracks.
