The Judiciar datasheet was built based on the Primaris Chaplain datasheet.

The Primaris Chaplain profile was reused in its entirety. The Chaplain in 9e always has a 4+ invulnerable save, while the Judiciar only has a 4+ invuln against melee, but unless we can find a good example of how this should be handled in Apocalypse, we are sticking with the Primaris Chaplain profile

The Primaris Chaplain doesn't get a pistol in apocalypse, so neither does the Judiciar.

The Primaris Chaplain and Judiciar PLs match in 9e, so we made them match in Apocalypse

Executioner Relic Blade

The 9e Executioner Relic Blade is very close to a Power Fist in terms of its statline - it has the same AP and Damage, and only 1 fewer strength. Pedro Kantor has a Power Fist - we used the same profile.

For the "Mortal Wounds on 6+" rule - we looked around for another unit with that rule, and found the Master of Executions - Axe of Dismemberment. The Axe of Dismemberment should be a good example - it is basically a power fist that does d3 damage instead of 2. Interestingly, the Axe of Dismemberment profile in Apocalypse is actually worse than the power fist profile. We will just reuse the Power Fist profile as is.

Tempormortis

Fight First / Fight Last are not concepts in Apocalypse, so this rule does not directly translate. We looked around for equivalents, and noticed that the Foul Blightspawn's Revolting Stench, which turns off fight first, becomes a simple -1 to hit in melee. We are going to make Tempormortis do the same thing.
