Corrosive Spread - Creep Tumors : Upgrade gives creep tumors ability to slowly drain HP of surrounding enemy units within a radius of 5. 1 HP of damage every 5 seconds. When tumor dies, it deals splash damage similar to banelings. Player cannot manually detonate the tumors.

this is too insane to be put in an upgrade to get the las tumor used to an active tumor would be more reasonable so that killing creep just puts it back for a while
