There are 3 playable races to choose from:
Each race has its own skill tree.
There are quite significant differences in movement speed between the races. Walking and running speed of humans is 20%* faster than those of the dwarves. Elves are even faster - they outrun dwarves by 30%*.
Races also vary in attack speed and attack combos.
Every race can equip any weapon and any shield. Armor pieces are, however, race specific. They can be identified by the prefix of the race infront of the armor's name. Runes are also equipable for every race and generally provide passive buffs, like extra walls hp regen, and more starting command points.
