Also venomancer should say some thing scary as he cast his ultimate. (Toxic attack? Really? Sound too plain). How about " Jidi got me, and now she's going to get YOU !!! HAHAHAHA..."
or " How's it feel to have venom dancing in your blood? That's my ecstacy ! heheheheheh..." or this one "I got you all a little gift from The Jidi isles... THIS !!!" opens his ultimate. That would be amazing for him.

You want to edit Kunkka's ultimate even more? I consider ... placing animate ghost pirates ( tiny in size but alot of them) on the ship yelling in rage, and if ghost ship succeeds they could be crying in victory.... if it fails they could be moaning in misery and loss. Or, instead of yelling they could be saying stuff like ( Kill ho the lot of em ! ) (Avast yee swabs ! ) ( Look at her go ! (The ship is "her") ) ( Look at the land lubbers go ! ) That would be awesome. And for supper effect... make the moans as bone chilling as ever.
