And here's what you get to work with:
Preternatural skill, the sodality, and inviolable psyche are unchanged from their WD rules.
Custodian armour doesn't give an invulnerable save, but all units have refractor field.
Praesidum shield confers a rerolll to invuln saves (against shooting and in combat), but doesn't give a 4+ anymore, just a -1 to hit them while in combat.
Custodes Terminator Armour = 2+/4++, relentless, can't run but can overwatch and sweeping advance.
All custodes infantry can take teleportation transponders.
Vexilla can be taken 1 per squad, confers fear, reroll failed leadership tests, and +1 to combat resolution to all friendly units within 12" (doesn't stack for multiples).
New wargear option called "arae-shrikes" any enemy unit attempting to deepstrike within 12" of a model with one of these (before scatter) must roll a d6, on a 4+ it suffers a mishap, even if it has rules otherwise (internal guidance systems etc). Also causes barrage weapons fired against the squad to roll 3d6 scatter taking the highest.
Guardian Spear has 3 versions, plain, melta and Adrathic
Custodes can have paragon spear (paragon blade meets guardian spear)
Cusodes have access to solarite power gaunlets and talons (what imperial fists have, with a lightning claw version)
