use a thaumanomicon, it explains every enchant:
Haste: 1-2-3
faster running for boots

Treasure: 1-2-3
Works exactly the way fortune works for pickaxes, just for wands of equal trade and excavation
Potency: 1-2-3
Makes wands more powerful, frost/lightning/fire have longer range, equal trade changes bigger areas, and excavate I think is faster but I might be wrong and is range.
Frugal: 1-2-3
Wands lose less durability when used.
