Wands
Wands are magical tools created by various wizards; each country boasts a particular wandmaker as the best, as expected. Each is made from woods of various types, with a core of one of the materials that resonates with the Watchtower of the user. If magic is cast while using the wand as a focus, the player adds a number of dice to the roll eqal to the Paradox die pool on the Gnosis chart on page 76 in the Mage corebok. However, if a wand is NOT used, the player subtracts that number of dice from the roll and loses the 10-again rule to the roll.
ALTERNATELY, wands can be ranked as level one to five artifacts. Once attuned with a (Gnosis+Wits) roll, the player adds the rating of the artifact in dice to any spell cast while using it. A wizard can be attuned to only one wand at a time, and must break the connection with an old wand before acquiring a new one. When using a wand that he or she is not attuned to, the player loses the 10-again rule to the spell roll in question.
