Well, since spells take so long to charge when they are being cast, why not create wands that the player can charge with one of their spells beforehand? Perhaps let the wand hold a certain number of SP of charges, so it could hold more charges of a spell like Magic bullet, and fewer charges of a spell such as Burning Hands or Small Snowstorm.
So basically, you could do something like
/charge Magic Bullet
when you are holding the wand.
The player would then sit there and add charges to the wand.
(Obviously it would take some time. Especially for spells with long charge times)
Charges would be added until:
1) The player runs out of SP.
2) The wand cannot hold any more SP.
Each wand can only be charged with one spell at a time.
Then when they use the wand, it fires off the spell without the player having to charge.
There could be varying strengths of wands like a 15 SP wand, and a 30 SP wand, and so on.
Oh well, just an idea to alleviate the strain on sorcerers.
