Warcry

When this is cast all enemys to the caster within 120ft, one size larger or less with an intelligence score of 6 or less, must make a DC 10 Wisdom check. On failing the check the target is immediately frightened for 1 hour, otherwise the target is unaffected by this spell for 24 hours.

The DC class of that check increases by 5 at character levels 5 and 15. The maximum intelligence score of a target increases by one for every two character levels
