The Boots of the Red Havoc have three charges, which are renewed at dawn each day.  Spending 1 or more charges creates an effect as described below.

1 charge: As a standard action, you strike the ground, causing a loud, ringing noise that breaks brittle, nonmagical objects.  Nonmagical objects of crystal, glass, ceramic, or porcelain within a 10-foot radius of the point of origin are smashed into dozens of pieces. Objects weighing more than 1 pound per your level are not affected, but all other objects of the appropriate composition are shattered.

2 charges: As a standard action, you strike the ground, causing it to attempt to hold all creatures in a 10 foot radius.  If they fail a save (Reflex, DC 10+Str modifier), their land speed is reduced to 5 feet until the beginning of your next turn.

3 charges: As a full round action, you strike the ground, releasing a shockwave that dazes (can take no actions, but has no penalty to AC) each creature within a 10 foot radius for 1 round (A DC 10+Str modifier Fortitude save reduces the effect to Nauseated (unable to attack, cast spells, concentrate on spells, or do anything else requiring attention. The only action such a character can take is a single move action per turn)).

These boots have left a trail of destruction in their wake.  No amount of cleaning will remove the drops of blood soaked into the boots' leather.
