The Mass Range Extender is a type of potion. It increases the mass range also known as the lifting capacity temporarily when used on a hoard both ways. The mass range bonus is dependant on the grade of the potion. For example, if the player were to use a grade 100 Mass Range Extender on a Rootax its Mass Range would be 0-100 WU except for 30-60 WU. Its grade gets a part of 30 so at grade 100 its -30/+30.
