Strength

Strength (represeneted by the icon ingame) is a stat that gives Health and Health regeneration. For each point of Strength your hero has, their max HP increases by 19, and and their health regeneration by 0.03 HP per second. Strength heroes are heroes whose Strength is higher than their Intelligence or Agility, and it also increases faster upon leveling. In addition, Strength heroes gain attack damage for each Strength point they have. This is the reason why Strength heroes tend to be harder to bring down, as their Strength coupled with the right items makes them tougher.

Health
Health (also known as HP) represents the life force of a hero. It appears in the UI as a green bar at the bottom of the screen. The left number, shows your current health, while the right number shows your max health. When your health reaches 0, you die. Health is increased every time you level, when you cast certain spells, or when you obtain items that give Strength.

Health Regeneration
Health Regeneration is a stat that determines the ammount of health a hero regains each second. It is shown as a small number with a + sign at the right side of the health bar. You can increase health regeneration with some spells, buying certain items or items that offer Strength, or using consumables such as Healing Salve. You can also get a health regeneration boost by activating a Regeneration Rune
