Inferno units, continued

Efreet/Efreet Sultan
Attack: 16/16
Defense: 12/14
Hit Points: 90/90
Damage: 16-24
Speed: 9/13
Movement: flight
Cost: 900/1100
Special Abilities: Immune to fire spells/Immune to fire spells; fire shield

The efreet is a good sixth-level unit, combining speed, offensive power, and durability. It is also immune to all fire spells, making it impervious to fireballs and the like. It also cannot be bloodlusted, though, so peruse the fire school carefully to see what spells can and cannot affect it. The efreet sultan is a significant upgrade because it is the fastest non-seventh-level troop (it shares the distinction with the lowly dragon fly). This gives you a huge tactical advantage in combat. The efreet sultan also has a permanent fire shield, which takes a portion of the damage dealt to the efreet sultans by the attacking unit and redirects it at them. The damage occurs after the attack is completed, and works even if the efreet sultan stack is killed. The upgrade, unlike most upgrades for this town, is thus significant.

Use the efreeti and efreet sultans to draw in enemy opponents and then unleash fireballs in the area, damaging surrounding enemies but leaving the efreeti unharmed. Keep in mind meteor shower is an earth spell. Efreeti are the natural enemies of genies, and inflict and receive 150 percent damage from these foes. Because genies are slower and have far fewer hit points than efreeti, this places them at a serious disadvantage to their fiery enemies.

Devil/Arch Devil
Attack: 19/26
Defense: 21/28
Hit Points: 160/200
Damage: 30-40/30-40
Speed: 11/17
Movement: Teleport
Cost: 2700+1 mercury/4500+2 mercury
Special Abilities: Teleportation, no retaliation, reduces enemy luck/Teleportation, no retaliation, reduces enemy luck

The devil is a good seventh creature, second only to the angel in speed and gifted with high attack and defense. The arch devil is more powerful still, but weaker than the dragons, titan, and archangel. The devil has awesome mobility, able to teleport instead of fly or walk. The arch devil can teleport anywhere on the tactical map. It is the second fastest unit in the game, behind the archangel. You should upgrade your devils as soon as possible, but both the initial dwelling and the upgraded dwelling are expensive. The arch devil is far superior to the bone dragons, behemoths, and hydras, but is much more expensive than its strength would indicate. It does the lowest damage of any seventh-level troop, and has the least hit points. However, it is fast and has good attack and defense. Cast spells such as frenzy and blood lust on it to increase its effectiveness. Both devils and arch devils reduce enemy luck by one. Their attacks cannot be retaliated against. Devils and arch devils are (im)mortal enemies of angels and archangels and do 150 percent damage to them.
