Dispel Magic can be used against a magic item to suppress it for 1d4
rounds. The dispeller makes a dispel check against 11 + the item's
caster level. (Artifacts are specifically listed as being immune)
Reference:

For normal magic items, the caster level is spelled out in the DMG entry.
However, for Weapons of Legacy, no such caster level is provided.
I see a couple of options:
1) Items of Legacy are essentially artifacts and cannot be dispelled.
2) Items of Legacy have a caster level that is "high" (perhaps epic).
Anyone got an opinion either way? Any rules address this situation?
