Keeper is a hero that can easily get alot of money really fast with illuminate, but you'll want to max out chakra because illuminate costs alot of mana. Once you have both maxed and should have alot of money, with boots and shadow blade, you can escape really easily by going invis, hiding in bushes and then tp out. That keeps you alive and with alot of money, you can afford to be credit to team..literally..buy them flying couriers, wards, gems, anything they need...even rapier
