You can use a heavy blade to inflict a deep wound on your foe, causing them to bleed heavily.

<php>echo “<b>Prerequisites:</b>”;</php> Str 15, Weapon Mastery (Heavy Blades)
<php>echo “<b>Benefit:</b>”;</php> As a standard action, you can make a single melee attack against a foe with a heavy blade. If the attack hits and successfully deals damage, the target becomes wounded, taking bleed damage equal to 5 + your Strength modifier at the beginning of each of their turns. Bleed damage can be stopped by a DC 15 Heal skill check or through any magical healing.
