There is noone in the party, that can reliably cast the
Ice Storm,
Fireball, or
Web spell (with a reasonable chance of success; Oog can technically UMD them, but the DC is rather high; Kordunn cannot cast them without
Read Magic (too bad it's personal) or being able to identify them via Spellcraft first), or the
Fog Cloud for that matter. The other scrolls are quite doable, there's only a reasonably small chance for failure.
Dirtan is a cleric (and a monk, obviously) and can also cast some of the divine scrolls (after using his
Read Magic), if you want to let him, in order to be able to use multiple ones at the same time.
The wands can be activated, though unless the spell is one that the activator knows, nothing will happen.
You can certainly try them, though, if you want to do that.
