Prepared for what one is about to do or experience; equipped or supplied with what is needed for some act or event; prepared for immediate movement or action; as, the troops are ready to march; ready for the journey.
Character sets action by an opponent to trigger his won action (i.e., readying to fire a bow at a Wizard whenever he casts a spell); acts in same phase as action is triggered; new phase becomes character's Initiative; if action is never triggered, character may choose a new action at his next normal turn
make ready or suitable or equip in advance for a particular purpose or for some use, event, etc; "Get the children ready for school!"; "prepare for war"; "I was fixing to leave town after I paid the hotel bill"
completely prepared or in condition for immediate action or use or progress; "get ready"; "she is ready to resign"; "the bridge is ready to collapse"; "I am ready to work"; "ready for action"; "ready for use"; "the soup will be ready in a minute"; "ready to learn to read"
standard action that lets a character prepare a partial action but delay its execution. Characters wishing to ready actions may do so on their regular turns in the initiative order. Such a character must specify both the action and the circumstances under which it will occur. Then the readied partial action may be taken at any time before the character’s next turn. (The partial action can even come before the action that triggers it.) For the rest of the fight, that character’s initiative result is the count on which the readied action occurred. If the character’s turn arrives again before the readied action has been taken, the readied action is lost, though the character can ready the same action a second time. Readying an action does not provoke an attack of opportunity, though the action being readied might. Readied actions are often used against spellcasters to disrupt casting or cast counterspells. Another common use is to ready long, piercing weapons against a charge. A readied weapon of this type deals double damage if the user hits charging character with it.
