Gear for Mayhem 10 Fl4k

I’m looking for a One Shotter Shield and the Kings/Queens Calls. The build is close to done otherwise.

For the One Shotter, I’m hoping for an ASE anoint, not picky on element. I know how rare one of these can be.

For the Kings/Queens Calls, I’m hoping for a 300% Weapon damage against enemies above 90% health anoint.

For whatever reason, my luck as a person is not great and I cannot get either of the Calls to drop.
