I think I know which option I'm going for.
And the first thing I tried doing was just coating my hand in mana and slashing at the mana connection.
Unfortunately, that didn't seem to work and my hand just passed through it like there was nothing there. Which physically is true.
But I saw that the mana coating my hand did make it stir a little.
The connection itself looked like a floating whisp of rope, that was made from a sparkling pink gas.
And the fact that my hand coated in mana was enough to at least affect it in some small capacity meant that I was on the right track at least.
Given that my hand seemed to have no effect, that meant that I had to rely purely on my mana to sever this connection.
My next thought was to just send a slash of mana at it but that didn't work either.
I also thought that it would be more difficult to do this from this side of the desk, so I climbed over and reached the succubus.
