There are two main types of playable units in Heroes of Aviel, Heroes and Soliders. A Hero is a powerful unit that can lead other units, each army must be led by a Hero and thus you must own one hero to play the game. Heroes are typically stronger than other units and they may have special abilities. Heroes stats and abilities can be enhanced by equipping items. Soldiers are the the standard units that make up most armies. Whereas heroes tend to have individual characteristics, stats and abilities, soldiers of a given type are all the same. Soldiers will typically have just one or two abilities tied to their archetype (a basic Priest can cast a Heal spell, a priestly Hero may have many spells). Soldiers are typically weaker than a Hero of a similar archetype, although this is not always the case, there are some very powerful Soldiers.
A typical Hero can lead a 5 person Squad which is made up of Soldiers or other Heroes. But some Heroes have the General keyword listed in their abilities. If a Hero has this keyword then the unit can be called a General and they are capable of leading an army much larger than the typical 5 man squad. This larger army, called a Platoon, can be made up of as many as 30 Soldiers plus the General!
Although Platoons cannot be used for adventuring (they cannot complete quests) these larger forces are critical for conquering and defending cities.
Every time a unit performs an action such as participating in a battle or quest they have the change to gain experience points. When a unit gets enough experience points it levels up and gains a new title and increased stats. Both Heroes and Soliders can level up, although there is more opportunity for progression for hero units, see below:
