Burn the Core: Use Magic Device. With a DC 40 Use Magic Device check, you can destroy a magic item in your possession as a standard action to cast a spell required for the item’s construction as if you had used a scroll. The caster level is the caster level of the item. You cannot use this ability on items that do not have specific spells required in their construction. If the item has an intelligence, it receives a saving throw against 10 + your Int modifier and gains a +4 bonus to this save.
And we finish off the new skill uses! Some of them, no doubt, ought to require feats, while others will rarely be needed. However, the important point here is to make some interesting new options available to clever players and GameMasters. Enjoy!
