CX-2‘s Unique Not Allowing Empire Allies to Target Enemies With Order 66
As you can see in the video CX-2 can ignore taunt just fine(for most of it but I’ll elaborate on that later), but no empire allies can ignore taunt to target enemies with order 66. The ability for this reads as: “At the start of battle, if CC-1119 "Appo" is an ally, all Empire allies can ignore taunt effects to target enemies inflicted with Order 66”
From how I read that it means that the only prerequisite for empire allies ignoring taunt is that Appo was an ally at the start of the battle, so it should be active.
Although I didn’t get a video of it, after all other DSCT‘s had died(Tarkin was still alive) CX-2 could no longer ignore taunt(except it eventually started working after tarkin killed three with his AOE). CX-2‘s unique that is responsible for allowing him to ignore taunt reads as: “While another Empire ally is active, CX-2 ignores taunt effects on his turn.”
It reads as thought the only requirement is one other Empire ally is alive, and it did work that way but it stopped for a period of time, so I thought I should mention it.
I should also mention that it wasn’t only the Knight Fall Trooper who was unable to target, he was just the next one that came up when recording. I first noticed it when I went to try do the massive damage on one of the other mandos with DCT and he was unable to target them.
