Problem

The matheroes is a group of 5 heroes, each having one and only one of the following superpowers: invisibility, wall-crawling, telekinesis, accelerated healing, and time traveling. An old guru will sell them some magical pills. Taking one pill will make the taker also have all the powers of the first matheroe he/she touches. As pills are extremely expensive, what's the minimum number of pills that need to be used by the group so that each matheroe obtains all 5 superpowers?
