You can use an to break the staff over your knee or against a solid surface, performing a Retributive Strike. The staff is destroyed and releases its remaining Magic in an explosion that expands to fill a 30-foot-radius sphere centered on it.

You have a 50 percent chance to instantly travel to a random Plane of existence, avoiding the explosion. If you fail to avoid the effect, you take Force damage equal to 16 × the number of charges in the staff. Every other creature in the area must make a DC 17 Fortitude. On a failed Contesting Roll, a creature takes an amount of damage based on how Far away it is from the point of origin, as shown in the following table. On a successful Contesting Roll, a creature takes half as much damage.

Distance from Origin Effect
10 FT. away or closer 8 × the number of charges in the staff
11 to 20 FT. away 6 × the number of charges in the staff
21 to 30 FT. away 4 × the number of charges in the staff
