Centaur
CentaurHealth: 8Attack: 5Shots: noneMovement: ground
70 gold (14)Hex size: 2Defence: 3Dmg: 2-3Spd: 6 (swift)
Centaurs and Centaur Captains are the best and the most expensive lvl 1 units.
 
Centaur Captain
Centaur CaptainHealth: 10Attack: 6Shots: noneMovement: ground
90 gold (14)Hex size: 2Defence: 3Dmg: 2-3Spd: 8 (very swift)
Haliberdier kills Centaur Captain in 1 on 1 combat, but speed makes Centaur Captains better. Centaur Captains are better attackers than defenders, so attack before attacked. Good upgrade.
 
Dwarf
DwarfHealth: 20Attack: 6Shots: noneMovement: ground
120 gold (8)Hex size: 1Defence: 7Dmg: 2-4Spd: 3 (very slow)
Special: 20% magic resistance.
Real slowdown for your hero. Good defenders. Good for garrison shooter defence. Toughest lvl 2 units.
 
Battle Dwarf
Battle DwarfHealth: 20Attack: 7Shots: noneMovement: ground
150 gold (8)Hex size: 1Defence: 7Dmg: 2-4Spd: 5 (slow)
Special: 40% magic resistance.
Now your hero can take them, speed will do until the endgame. Resists about 2 out of 5 spells!
 
Wood Elf
Wood ElfHealth: 15Attack: 9Shots: 24Movement: ground
200 gold (7)Hex size: 1Defence: 5Dmg: 3-5Spd: 6 (swift)
The only shooter for Rampart. Elves are offensive units and need a good defence.
 
Grand Elf
Grand ElfHealth: 15Attack: 9Shots: 24Movement: ground
225 gold (7)Hex size: 1Defence: 5Dmg: 3-5Spd: 7 (extra swift)
Special: fires two shots per attack.
Awesome upgrade - doubles the attack and costs only 25 gold extra!
 
Pegasus
PegasusHealth: 30Attack: 9Shots: noneMovement: flying
250 gold (5)Hex size: 2Defence: 8Dmg: 5-9Spd: 8 (very swift)
Special: enemy spellcasters must pay 2 extra spell points per spell when Pegasi are present.
If you're short on money, 1 Pegasus is better than 3 Centaurs and more useful than 2 Dwarves.
 
Silver Pegasus
Silver PegasusHealth: 30Attack: 9Shots: noneMovement: flying
275 gold (5)Hex size: 2Defence: 10Dmg: 5-9Spd: 12 (extra quick)
Special: enemy spellcasters must pay 2 extra spell points per spell when Silver Pegasi are present.
Weakest non-shooting lvl 4 unit, but really fast and annoying to enemy spellcasters. Highest pop among lvl 4.
 
Dendroid Guard
Dendroid GuardHealth: 55Attack: 9Shots: noneMovement: ground
350 gold (3)Hex size: 1Defence: 12Dmg: 10-14Spd: 3 (very slow)
Special: creatures attacked by Dendroids are held in place by their roots until Dendroids move or are killed.
Way too slow for hero's army, but excellent for garrison - Dendroid's roots will hold flies in place while Elves do their job from a very nice close-up. Worst lvl 5 unit but maximum population is the highest among lvl 5.
 
Dendroid Soldier
Dendroid SoldierHealth: 65Attack: 9Shots: noneMovement: ground
425 gold (3)Hex size: 1Defence: 12Dmg: 10-14Spd: 4 (very slow)
Special: creatures attacked by Dendroids are held in place by their roots until Dendroids move or are killed.
Really hard to identify the upgrade by picture, but if you look closer, Dendroid Soldiers have a few extra branches and bigger feet :) Bad upgrade: 1sp and 10hp for 75 gold! Too slow for hero, excellent for garrison.
 
Unicorn
UnicornHealth: 90Attack: 15Shots: noneMovement: ground
850 gold (2)Hex size: 2Defence: 14Dmg: 18-22Spd: 7 (extra swift)
Special: 20% chance to blind enemy. Aura increases magic resistace of all adjacent creatures by 20%.
Note that Unicorn's aura does not affect the Unicorn itself. Unit surrounded by few stacks of Unicorns cold be almost invinsible to magic! Unicorns are good for any combat situations.
 
War Unicorn
War UnicornHealth: 110Attack: 15Shots: noneMovement: ground
950 gold (2)Hex size: 2Defence: 14Dmg: 18-22Spd: 9 (ultra swift)
Special: 20% chance to blind enemy. Aura increases magic resistace of all adjacent creatures by 20%.
Good upgrade makes unicorn an excellent lvl 6 unit with a very small price!
 
Green Dragon
Green DragonHealth: 180Attack: 18Shots: noneMovement: flying
2400g + 1c (1)Hex size: 2Defence: 18Dmg: 40-50Spd: 10 (super swift)
Special: attack affects 2 hexes. Immune to spells levels 1-3.
A little weaker, cheaper and slower than Red Dragon, otherways indentical.
 
Gold Dragon
Gold DragonHealth: 250Attack: 27Shots: noneMovement: flying
4000g + 2c (1)Hex size: 2Defence: 27Dmg: 40-50Spd: 16 (fast)
Special: attack affects 2 hexes. Immune to spells levels 1-4.
While equal in price to Black Dragon, Gold Dragon has less immunity and hit points, but has more attack, defence and speed. Has a little weak spot for powerful enemy earth spellcasters - lvl 5 implosion.
