IK Armor is found with the Lustplate if you do the optional dungeon in Ch1 (And didn't have an absurd amount of Sx). IK Helmet is found in the war vaults in Ch2. IK Shield is found if you invest political capital in Riala's project in the 3AW aftermath in Ch3. IK Pin is found in the Ancient Ruin in Ch4.

The Mother's Guard dude starts out next to the big meeting place bridge on the Gheldarese side of the river, but only appears after you talk to Janine. He (and all the other moving characters on this map) can wander out of sight under the canopy. You can try waiting in the general area for him to emerge or the and go under the canopy while pressing the action button and hope you hit him by accident.
