Yes, wands can be rather dangerous. Even a single one.
Wand ready timer activates when wand is wielded and the cooldown begins after use. The timer counts individually for each wand.
So it is possible to wield two wands and have them both at the ready. Using both wands at the exact same time should be impossible(will try to test this today), IMHO, as a mage cannot multicast any other magics either. It is very possibe to use the other and then the second one though and have the spells at the ready.
I cannot but to see potential for great overkill here even if the current mage players are quite careful and cautious(perhaps even bit too much?)with how magic affects the game. Someday something will happen that will draw attention to this so perhaps it is better to discuss this now before anyone has become severely dismayed by some IC event
Wizzie feedback also appreciated
