Ice gets juiced cause it is the only path with multi hit iceshards and iceneedles. Air tends to get juiced cause a lot of invokers are arials and they naturally get a buff to air.

I would personally not recommend dropping any path. Invokers have a spell for every situation you lose that as you drop paths.

You can have a pit and quicksand but you have to do it in a specific order I forget which it is. I think you have to quicksand and then pit. But cant pit then quicksand.

You can recall from pits yes the invoker will vanish from where while they are in the pit everyone else in it will show though.

Its been a while but I'm fairly sure vortex and quicksand the vortex happens first and flings them out but if they stand against the vortex they will sink into the quicksand. But if you are flying the vortex hits you more often.

They have no means of zapping movement that would be just dumb if they could. They are already just absolutely rediculous.

Adhesive web will lag them if they are an arial or bird form and it basically earthbinds them.
