Combat consists of a series of combat rounds, each of which represents six seconds of time. After each round is resolved, if there are still creatures engaged in combat, start a new round. Continue until all combatants are unable to fight or have willingly ceased fighting

A round of combat consists of three segments, which are resolved individually and in succession

Each segment is resolved in the following manner:

1. Each player and NPC takes their turn, in order of initiative ranking
2. On their turn, a player or NPC may initiate a single action (Full, Standard, Move, or Swift)
3. One segment (2 seconds) of their action plays out, and any of their ongoing actions also advance by one segment (2 seconds)
4. After all players have taken their turn, combat advances to the next segment

If a creature is targeted with an attack, and the attack would reach the creature before their turn in the initiative order, then the targeted creature has the option to defend themselves provided that they have an unspent action to do so. If the defender chooses not to use a counter-action, then the attack is resolved immediately. If the targeted creature chooses to take an action, they must declare their chosen action, and the resolution of the attack takes place on the defending creature's turn in the initiative order
