Air Elemental:Air elementals are the second best unupgraded level 3 creatures. The incredible thing is that they are themselves only level 2 creatures. In every way their statistics are great and they cannot be blinded too. There are three severe drawbacks as well. Their basic growth is very low, even lower than many level 3 creatures. The second drawback is their vulnerability for Lightning spells. The last drawback is their cost in gold, comparable to the cost of a level 3 creature. These powerful but vulnerable creatures become even more powerful when upgraded.
Earth Elemental:Earth Elementals are without any doubt at all the very worst level 5 creatures ever. They are too slow to be useful in combat, their Attack and Defense skills are low and their damage is unimaginably low. In fact, their damage is so extremely low that it would seem to be a level 3 creature in stead of a level 5 one. Their immunity is ok, but their vulnerability is quite dangerous as well. They cost not that much and their basic growth is better than average, but they are not capable of dealing with a job more difficult than defending a town when no better creatures are present.
Energy Elemental:Energy Elementals are faster than Fire Elementals and they can fly for only a small increase in cost. They still are rather weak creatures that are only useful in a combo with Armageddon or if you have no other troops to deploy in your army.
Firebird:Firebirds are one of the weakest but cheapest unupgraded level 7 creatures. Their fire immunity is great, as is their breath attack. Their speed is unmatched among unupgraded level 7 creatures, but the thing that is really astounding is their basic growth. Their basic growth is 2 in stead of 1, this means twice as much Firebirds as any other level 7 creature. Given enough time, you can accumulate a stack of Firebirds that large, that you can overpower any army. Upgraded they become even more dangerous.
Fire Elemental:This is where things start to go wrong in the Conflux ranks. Fire elementals are among the worst level 4 creatures in the game. They have a descent health, average Attack and Defense skills, an above average speed and a nice basic growth. Seems nice, but they deal hardly any damage and they cost too much. The increased damage from cold spells is not a good thing either but fire immunity is pretty neat. Upgraded they become a bit more valuable.
Ice Elemental:Ice Elementals can be called the best upgraded level 3 creature. They have a better speed than Water Elementals, are able to cast Protection From Water and they have a powerful ranged attack. The speed of Ice Elementals is still quite slow and they suffer from a melee penalty so they definitely need some protectors to guard them in combat.
Magic Elemental:Magic Elementals are not the weakest upgraded level 6 creatures, in large numbers they can even form a very powerful stack in your army. They are immune to all magic, this means that they cannot be resurrected, but this also means that they are almost unstoppable. Together with their increased damage, increased health and faster speed for a mild increase in cost; this makes Magic Elementals a valuable part of any Conflux army.
Magma Elemental:Magma Elementals are still the worst upgraded level 5 creatures, but their speed is better and their damage is increased some. They are definitely more capable of defending your town than Earth Elementals, so buy these if you really really need defenders and have sufficing funds.
Phoenix:Phoenix have more healthpoints, an increased attack skill and a very much enhanced speed. They still are among the weakest upgraded level 7 creatures but they are the cheapest too and their speed is unmatched in the game. All the elements that make Firebirds so good also apply to Phoenix, meaning that the Armageddon combo is also applicable on Phoenix. The Rebirth ability is really useful. One fifth of the original stack of Phoenix is resurrected automatically when the last of the stack dies. Unfortunately, this means that the original stack must be wiped out first. Might be interesting to split phoenix up in multiple small stacks for a better chance to get Rebirth. Check the Clone spell for a combo too.
Pixie:Pixies are the cheapest and weakest allied (not neutral) creatures and the second worst units in the game. Even in large numbers they remain quite useless and should be upgraded as soon as possible. The only possible functions for Pixies in an early army are being able to cast a spell before the enemy hero can, (Pixies are the fastest unupgraded level 1 creatures) or absorbing damage from enemy ranged attackers so your own ranged attackers stay safe.
Psychic Elemental:Several level 6 creatures have better statistics than Psychic Elementals. This does not mean that they are completely useless. Their mind spell immunity is very nice and a number of spells are particularily interesting to use on them. (Bless, Counterstrike, Haste, Prayer...) They suffer a bit from the wide damage range but their no enemy retaliation and their spread attack make them a unit the enemy forces must try to avoid at all times. When upgraded, they become much more powerful but a number of combos are lost since the upgrade is immune to all spells.
Sprite:Sprites are still the weakest upgraded level 1 creatures but they have many advantages over Pixies for only a few goldpieces more. Their damage range is sligtly increased, as is their speed. Because their speed is unmatched among other level 1 creatures and because they are the only flying level 1 unit (with no enemy retaliation) plus the fact that their basic growth is enormous, Sprites can really form a very powerful unit during the early game. Unfortunately most Sprites will have perished by the end of the early game so that they cannot form more than a sacrificial stack in an important army.
Storm Elemental:Storm Elementals are the deadliest upgraded level 2 creatures in the game. With their many shots they are very reliable ranged attackers. Their no melee penalty makes them very capable of melee combat as well. They can cast Protection From Air, which is nice. (but not super) Be sure to take advantage of their large damage range by using Bless on them and beware of Lightning spells.
Water Elemental:Water Elementals are the best unupgraded level 3 creatures in the game. They have lots of healthpoints, a great Attack and Defense skill and a smaller damage range than Air- and Storm Elementals. Their immunities and vulnerabilities are not as severe as those of the Air- and Storm Elementals and Water Elementals cannot be blinded as well. Some drawbacks are their cost in gold and their low basic growth. Their largest problem is their relatively slow speed. When upgraded, Water Elementals become the second great ranged attackers of the Conflux.
