I have a Image for character:
And good idea.
Hero will cant to take permanent control from the neutral creeps.
This Sludge, by himself, will be very weak, but if he will parasite(combine) with ally hero, he will do it much stronger, faster etc

or to repeat last spell of parasidet hero. I have lot of ideas and bad english language
I need help, who want to do this hero, with me leave here message.
