The most important thing that new players of Footmen Frenzy tend to miss, is using healing salves. They are free and available from the Wut're ya buyin'? shop at the back of your base. They turn off if you are attacked, however, they are your best option considering base healing was removed in 5.0. The beacon next to your base has an ability which puts a salve on a nearby hero. Note: Unless otherwise mentioned in the guides, durations on single-target spells that affect both heroes and units are listed for heroes, since you are more likely to cast the spells on heroes.
