Making hero devour ability

I want to make an ability where my hero shoots out a missle effect and devours a unit for a certain amount of time.. is that possible?

btw its a frog ability for him shooting his tongue out to eat something..

If you have TFT it should be easy enough. Just make devour a hero ability and give it a range and a projectile movement speed and add in whatever projectile art you want, then make a trigger that makes the hero drop the unit after a certain period of time, but I'm not sure if you can make the devoured unit take damage over time, since devour is actually a combination of two different abilities.

Well as far as I can see there is no "level" stat on a unit ability.. and I want the ability to level

I think you can make it a hero ability some where in there.

Just set the box for 'Hero Ability' to true, click a different ability, click back, and a Column called Stats-Levels should show up.
