In the Campaign my group is running we have a Broodmother Dryder. It takes several hours normally for the gestation of impregnated victims before the creature inside emerges and matures.
I've been running over it with the others, but every method of quickening the gestation time that we came up with seems to be flawed or confusing, especially during combat.
How can the Broodmother's spawn growing time be reduced outside of combat?
(preferably within only an hour).
How can the turns during combat be reduced for the spawn to hatch?
(preferably down to 2 rounds)
