Minion Waves
These waves will consist of upwards of 100 Minions, starting off at 50 minions and going up by 25 each wave of minions you fully clear out.
Minion Mix Waves
These Waves will contain primarily minions, but also come with 1 pike for every 10 minions and 1 officer for every 5 Pikes. This results in a wave of 100 Minions, 10 Pikemen, and 2 Officers.
Pikemen Waves
These waves contain at most 50 Pikemen, starting off with 10 Pikemen and growing by 10 with each wave of pikemen cleared.
Pikemen Mix Waves
These waves will contain Pikemen, Officers, and a Commander. 1 Officer for every 5 pikemen. Only 1 Commander will be present during these waves.
Warrior Waves
There are no Mixed waves for this, but this wave will consist of 4 AI Warriors, hailing from the same faction that the minions, officers, and commanders are from. So if you see Viking Minions, you will only see Viking Warriors like Warlord, Shaman, and Raider.
Wu Lin Bonus Waves
This wave will spawn Neutral Wu Lin Warriors that will attack both you and the oncoming enemies. Killing the Wu Lin will grant you with any renown they gained from defeating enemies in your wave, the base AI Warrior renown, and a bonus of 100 Renown.
Heroic Wave
This wave is where you all will Very Likely die at. 200 Minions, 50 Pikemen, 15 Officers, 4 AI Warriors, 2 Commanders, and the Legendary Hero. Should you beat this wave, you will have won the Final Stand and will receive an exclusive outfit, ornament, effect, and execution or your character that you used, all based on the faction you just defeated.
This may seem like to much to handle, but the rewards are all worth it. But what if you do not win? Well the rewards are 5 Scavenged Pieces for your character, some steel, and an effect for your character. The more Renown you get, the better the rewards.
