Spell channeling
From UOGuide
Spell Channeling is an item property that allows Magery spells to be cast without unequipping the Right and Left Hand equipment slots. It is always accompanied by a FC penalty of -1 (which does not count as an additional property), though this may be cancelled out if the item has a FC bonus as well (if you don't see a penalty/bonus, then your casting rate remains the same).
For example, an item displaying spell channeling with a FC of -1 has a single property. A spell channeling item seemingly without the penalty has at least two properties. Keep this in mind when crafting magic items.
On the other hand, some artifacts grant a FC bonus that seems to outweigh the penalty inflicted by the spell channeling property. For example, the Arcane Shield and Boomstick grant spell channeling as well as FC+1.
Spellbooks do not require spell channeling in order to stay equipped while casting. Wands always have this property.
