Subject: Modify Ely's "Destroy Weapon" invocation and Trog's "Brothers in Arms

Ely: Items of high value (artefacts etc.) are very likely
     to raise piety. For the rest, the probability depends
     on piety.

Trog: BiA has a fixed cost of 4 to which a piety dependent
      bonus is added, making the total piety cost range
      from 4 (bears) to 7 (giants). Also, the intermediate
      monsters (oges and trolls) turn up over a longer piety
      range.
