[edit] Description

With great offensive and defensive power and flying abiliy, Archangels are among the mightiest creatures in the game.

[edit] Dwelling

Archangels are recruited from Upgraded Portals of Glory.

[edit] Upgrading

This is the upgraded version of the Angel.

[edit] Comments

One of the strongest units in the game. Their only downside is the lack of immunities and rather high cost. Great speed and special.

[edit] Strategy

Cloned Archangels gets one casting of Resurrection. They are also often better at resurrecting than the hero, so one could create a clone, let it resurrect, destroy it the next turn (if the enemy didn't get at it first, preferably by letting it attack something that kills it by retal, but area effect spells like Frost Ring or Fireball also work), and create another one.

It takes three archangels to resurrect another archangel. It is good if you have more than 6 archangels to divide them into stacks with multiples of three (3,6,9,12 and so on...) in them, so they can resurrect each other.

Because their damage is not based on a range of numbers, but is instead set at 50. Spells like bless and curse have no effect on them. Because they do a precise amount of damage in combat, they are a sure fire unit.
