A strong, defensive character. Has a good mix of counter attacks and harassment abilities.
Shield Bash Unblockable that allows damaging follow ups, and Light and Heavy Attack options that can easily frustrate and confuse defenders.
Cons
Stamina dependent, runs out of Stamina easily whether attacking or defending.
Unable to Feint, Full Block does not provide as many options and costs stamina.
Strategy
The Shield Bash Special can be used after a Heavy Attack, Side Dash or from Full Block. It is Unblockable and can't be parried, but fairly weak to side Dash. Despite this when it connects it guarantees a Light Attack follow up which can chain into the Conscript's Attrition infinite Chain. Shield Bash is quite possibly the most important move for starting your offense as a Conqueror.
The Conqueror has an unusual Heavy Attack that can be quite punishing for the unprepared and can be used as a decent opener or from outside normal range. Charging increases damage and speed and does not prevent you from blocking, your only setback is the Stamina drain while charging, don't hesitate in canceling the charge if the enemy is backing away (this is done by pressing the Feint and releasing Heavy Attack at the same).
The Conqueror is naturally a defensive character and is dependent on Stamina to make powerful plays. So with that in mind, use your Superior Blocking trait and Dashes to set up opportunities to Shield Bash into conservative Chain Attacks rather than attempting to overwhelm your opponent.
