Units with Lifesteal are indicated by a red heart with a "+" in the icon slot.
What Does Lifesteal Do?
Units with Lifesteal have a vampire-like quality: when the damage an enemy unit or the main enemy character they also gain health for your main character. In order for this health drain to work the unit needs to actually connect and do damage.
The amount of health your character gains is always equal to the total damage of the Lifesteal unit, even if it doesn't need to do that much damage to kill its opponent. So if a unit with Lifesteal and 5 attack is bloked by and kills a unit with only 2 health, your character will still gain 5 health.
