Regeneration is the ability for a unit to self-heal their hit points without the need of a healer, first introduced in Age of Empires II. Units with regeneration are valuable in pitched battles and often essential in campaign scenarios where the player cannot build a base and train units, but has to fight their way through with a starting army.
Age of Empires II Edit
In Age of Empires II, there are a few units that can regenerate, most notably the Berserk. With the release of The Conquerors all heroes gain a regeneration ability, making them very valuable in campaign scenarios. Often, heroes are also must-survive units, and the regeneration ability aids the player greatly since they can actually use the heroes in front line battles instead of just having to protect them.
Among regular trainable units, regeneration is a fairly exclusive trait. The Berserk is the only unit to have an innate regeneration ability which can be furthered by researching Berserkergang. Berber camel units (Camels and Camel Archers) gain a regeneration ability once Maghrabi Camels is researched.
Regeneration rates Edit
- Heroes: 30 HP per minute
- Berserk: 20 HP per minute (40 HP per minute with Berserkergang)
- Berber camel units: 15 HP per minute (after researching Maghrabi Camels)
Age of Mythology Edit
In general, regeneration is a more expanded feature in Age of Mythology, with several major and minor gods having access to certain regeneration-related features. When a unit has finished regenerating, it will briefly shine a green hue (see gallery).
God bonuses and technologies Edit
Gaia enables buildings to slowly regenerate 1.0 HP/second.
- Hephaestus Revenge (Leto) enables Automatons to regenerate 1.0 HP/second.
- Heroic Renewal (Hyperion) enables heroes to regenerate 1.5 HP/second.
- Mythic Rejuvenation (Hekate) enables myth units to regenerate 2.0 HP/second.
- Acupuncture (Nü Wa) enables Peasants to regenerate 0.5 HP/second.
- Elixir of Immortality (Chang'e) enables Immortals to regenerate 2.0 HP/second.
Myth units Edit
- Colossus (Hephaestus) can heal themselves by eating gold or trees. The rate is 30.0 HP/second.
- Wadjet (Ptah) regenerates 1.0 HP per second.
- Troll (Forseti) regenerates HP equal to the damage it causes.
- Behemoth (Rheia) regenerates 1.0 HP/second.
- Jiangshi (Zhong Kui) regenerates by fighting, similarly to the Troll. The rate is 1.0 HP/4 damage dealt.
Additionally, all campaign heroes (Arkantos, Amanra, Zhi, etc.) slowly regenerate, similarly to Age of Empires II, but don't die, unlike in Age of Empires II. Instead, when they reach 1 HP, they collapse and have to be revived by having friendly units approach them.
There are other units and buildings found in the campaigns that demonstrate the ability to regenerate HP. In the Fall of the Trident campaign, the Living Poseidon Statue from the A Place in My Dreams scenario regenerates HP at tremendous speed. Only Arkantos in his demi-god form, who also regenerates quickly, can destroy it.
In The New Atlantis campaign, various Titans demonstrate an ability to quickly regenerate as well. These include Prometheus in Betrayal at Sikyos and Kronos and Gaia in War of the Titans. The Tower of Odin is a special Wonder that regenerates at such a high speed that the only way to get rid of it is with the Deconstruction Wonder god power.
Age of Empires III Edit
Heroes (such as Explorers and War Chiefs) remain the most notable units that slowly heal hit points over time. Similarly to Age of Mythology, they collapse once their HP reaches 1, but unlike in Age of Mythology, their hit points don't stop regenerating when they have collapsed.
These units are included among heroes and as such, conform to the above-mentioned mechanics:
