Engagement is all about the core of Wargaming: Killing shit!
Engagement begins with the Players taking it in turns to have Warriors declare their Targets.
These Engagements are resolved with Attack Challenges which are typically Aggression versus Aggression unless it is a base to base Melee Engagement in which case it is Grit versus Grit.
The Winner of the Challenge can use her Margin of Success to attempt to Inflict Injury or Close the distance to her Enemy.
Injury uses the tried and tested system from Doxy and Weird and Wonderful.
Cover is a simple bonus to Injury Resistance and Hidden Warriors have the option of making a Pop Up Attack for a bonus to the Attack Challenge.
Falling is treated as an Attack with a Margin of Success equal to the number of Floors fallen.
Rather than the typical you go, I go of other Wargames Whores Blade 20,000 replicates the chaos of battle as players take it in Turns to Move or Engage with individual Warriors rather than their whole Warband.
Who goes first? Well the Warband with the highest Courage gets to choose which of the two Phases to assign priority to and thus act first in. In the other Phase the other Warband acts first.
