Y1) when in werewolf form i seem to aautomatically arm a spell aand a staff which stops me from fighting. How do i stop this?

2) noob question but how do i recharge magical weapons with a soulstone? Sorry for being brief im on the mobile, thanks

1.I dont know, sorry
2. you need filled soul gems

No clue on the first one but on the second you need a filled soul gem. Then you open your inventory and go to the weapon to recharge. There should be a button you can press (T on PC, no clue for consoles) and it will bring up a recharge menu.

Edit: Ninjered (Should be A on xbox)

Werewolf: Unequip your weapons. It seems to work for me. By unequip, don't have anything selected.

1: No idea, probably a bug. Try removing those weapons as equipped and favourites and see if that works.
2: Select the weapon that needs recharging in your inventory and press "T" (for PC version) or the button shown in the bottom left side of the screen (like [X] to recharge [A] to favourite). Then scroll through your list of soulstones and slect which one.

It is right bumper on 360. Go to inventory and highlight weapon to charge and press right bumper. If it needs a charge it will come up with a list of the filled soul gems in your inventory. Select the one you want and then click A, now it has been recharged

And it is R2 on PS3.
