Reinforcement

Creep are any form of units that come out of teleport portals. Their name stems from the fact that they are largely insignificant in power, are are generally there only to slow down the larger Demigods, or to help them gain experience.

Creep can be unlocked from your Citadel for some gold, provided your war rank is high enough. Creep's power can also be upgraded at your citadel.

the creep you can unlock are:

• Minautors (start unlocked, war rank 1) : Basic melee unit. Armed with a hammer, the soldier is most effective when used in groups.
• Archers (start unlocked, war rank 2) : Fragile, ranged unit. Most effective when they are supported by frontline melee troops.
• Priests (1800 gold) : Heals all nearby friendly units. Since they inflict very little damage, they must be protected by other troops.
• Angels (3600 gold) : Aerial units that swoop in and inflict melee damage.
• Catapultasauri (4800 gold) : Specializes at medium-ranged assault. Its tail throws a massive rock that is especially effective against structures and large groups of units.
• Giants (6400 gold) : Big, brawling melee unit. Rumbles into range of its enemies and then smashes them with its club.

It is actually recommended to NOT unlock creep too early into the game, as they will be feeding experience to your opponent, for not much benefit on your side. Rather, it is recommended to save your gold until you can unlock everything up to Catapultasaurus.
