ToME: the Tales of Maj'Eyal

I noticed that, when I equip ammo in the ammo slot, my shooting talents grey out, and I can no longer shoot my telekinetically wielded bow. Is this a bug, or intentional?
I only tried with purple ego ammo, so I don't know if this goes for blue and normal ammo as well.

Did you equip arrows or shot? Shot does not work with bows, and arrows do not work with slings.

Now that you mention.. I'm not 100% sure that I was trying arrows. I'll try again on my next Mindslayer.
