As a full-round action, you provide tactical
aid to all of your allies within sight and
voice range of your position. When you do so, you
make a Knowledge skill check
against DC 20. If your skill check succeeds, your allies
gain a +1 competence bonus on initiative rolls, attack
rolls, or defense rolls for 2d4+1 rounds. If your roll succeeds by
10 or more point, increase the bonus to +2. If it
succeeds by 20 or more points, your allies gain a +3
competence bonus.
