GM Guidelines

Design Decisions
Avoid effects which require keeping count of rounds.

NPC Morale
The first step of each combat round is checking NPC morale. Group morale must be checked first, this is a subjective evaluation of the likely result of combat.

Next each NPC must be checked.

These values may need to be changed after play-testing.

Withdraw means that the NPC will Retreat, and will continue to Retreat until able to exit the combat. NPCs who Withdraw will try to make defensive formations as they retreat. Flee means the NPC takes a movement action, giving advantage to any attacks, and losing his action if hit before he moves. Note that a retreat action requires between 10' and 20' movement directly (more or less) away from attacker.

Unnatural Creatures
Summoned, animated, undead, and similar creatures come in 3 forms:
 * 1) Incorporeal creatures are all spirit; a weapon will pass through them harmlessly.
 * 2) Semi-corporeal creatures can manifest a physical form, but that form dissolves when the creature is "killed."
 * 3) Fully-corporeal creatures have a permanent body which leaves a corpse after death.

Normal people and animals are technically also corporeal, but to avoid confusion we will just call them "normal". "Fully-corporeal" refers to unnatural creatures.
