Next attempt (actually combination of many attempts):

It posses following powers bestowed upon it by the Maker himself.
  [E] [*********-] Convert 14% of 'wis' (up to 400 stat) as extra spell damage
  [U] [***-------] Increase 'wis' stat by crude amount
  [U] [----------] Increase damage attribute by pathetic amount
  [R] [*******---] Increase your ability to avoid ambush by great amount

One decent I guess - others not so... escpecially the apparent zero +dmg
doesn't tempt much as [U]-level enchantment.
