There is a quest in Conqueror’s Blade that players have to do sometimes which requests to absorb X amount of damage specifically by “Eastern Spearmen”.
This is very confusing because the game never explains to you the origins of different units and does not guide you in any way after being “forced” to do this quest.
This also happened to me and i was completely confused trying to use various spear units that I had and after every battle I would check if there was progress for this quest and there was zero. This was very frustrating.
An example of quest text: “Shield of the east: use Eastern Spearmen to withstand 200,000 damage”.
So which Spear units qualify as “Eastern” & which you should choose:
There are 3 units only. They can all be visually identified by their massive shields:
Spear Militia
With only 100 Leadership these are a very good “wall” unit to use in battle. They get the job done and cost very little to re-supply. They are also very cheap to unlock with Honor. Choose these to maximize your daily income per battle.
Imperial Spear Guards
These are a high tier unit, heavily used in important battles such as Territory Wars. Even though some players do, I would not recommend using these in daily battles because you will have to pay a lot of money to re-supply them given their high tier status. This would completely destroy your income. Choose these if you already have units for daily battles and/or if you do not have any “wall” unit to use in Rebel Camp battles or Territory Wars.
Ironcap Spearmen
These are in between the Imperial Spear Guards and Spear Militia, so they are neither cheap nor excellent, but a bit of both, which can work for those players who do not want to go to either extreme. I would not choose these personally since I prefer specific roles, but if you want something in between then these are for you.
