Tsyr said:And I'll be frank. The guy just *doesn't* know the rules all that well. If you can prove him wrong, he normaly goes with the correct way... but unless you can prove him wrong, he wont. So I'm trying to prove him wrong as conclusivly as I can.
1) To use a wand you must hold THAT wand in your hand just so and utter the command word. How can you really hold ten wands in your hand simultaneously, even if they are all welded together somehow?
2) The fact that it is a standard action to activate a single magic item has already been mentioned.
3) You must convince this DM that he is really screwing himself by allowing this kind of thing. A DM should never underestimate the unpredictability and resourcefulness of a group of PCs. There is a real possibility that this uber-wand could fall into the hands of the PCs. Then what would happen to his game? Even if YOU can't use it, you could always hire an NPC wizard who could!!!
4) If you can tie a bunch of wands together and have them work in concert in his world, then any PC with a meta-magic item creation feat and two brain cells to rub together will utterly destroy his game.
If your DM can not be shaken out of his fit of insanity and you must play against this NPC, I suggest that your party do the following:
Buy a boatload of tanglefoot bags and smokesticks.
For each PC in the party, tie a couple tanglefoot backs together and strap several handfuls of smokesticks to the thing (after the DM has shown you that it's OK to tie things together and use them all at once).
Everyone should always have this bag in their hands. After all, this wand-wielding bastard is out to kill you when you least expect it.
Next time the bastard appears, every PC disregards everything else and nails him with the makeshift weapon they are carrying.
At least a few of the smoke sticks will go off, preventing the wand-wielding bastard from targeting anyone. Hopefully he'll fail his save on at least one of the tanglefoot bags and be stuck in place.
Then mass-grapple this wand-weilding bastard, and take him out!
