Unfaltering Zone [RS]

You thrive in combat, gaining power for every second you spend in battle. Your fervor for battle spreads to your allies.

You create a 30-foot radius magic zone that follows and is centered on yourself. This spell can affect any number of creatures of your choice even if they are not in sight. You choose one of the two effects when casting the spell. Casting this spell on the same round it has ended retains the effect from when it wore off and allows the caster to change the effect.

1. You gradually increase the attack of allies in the zone. For every round the zone is up, allies dealing damage in the zone can add a +1 bonus to their damage to a maximum bonus of +2.
2. You gradually increase the defense of allies in the zone. For every round the zone is up, allies taking damage in the zone can gain damage reduction bonus by +1 to a maximum bonus of +2.

If more than one zone of this spell overlaps, the zone with the presently higher bonus suppresses the zone with the weaker bonus but does not dispel it.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the maximum bonus increases by +2 for each slot level above 1st.
