Shocked at no shout outs to the self-same trial.
I always crouch and sneak everyone into ambush positions directly behind their counterparts, but I must've done that trial two dozen times by now and I still don't know why sometimes hitting a non-you curses you and sometimes it doesn't.
Not to mention if you CAN'T kill the you in two turns (ambush turn and the turn before they get a go)... then you're in for about 100 Disarming Attacks which are by far my least favourite thing to go against!
The Self-same Trial has plenty of ways to cheese it.
Personally, I tend to just go in with one character (Normally whomever is best at bursting a target down). That way it's a 1v1 where the entire fight lasts like 1 round as someone like a Fighter who's pre-buffed with Haste and uses Action Surge just goes to town.
You can also make it much easier by unequipping your gear before heading in. Since the copies copy your gear, removing everything makes them weak (Outside of spell casters, though you might also be able to prepare bad spells. I'm not sure if they copy what you're prepared or not) - Which can also be useful with the aforementioned Fighter 1v1 if you unequip your armour so the copy has low AC for you to smack down. (If you sneak in you can re-equip your characters before engaging to boot)
As for the cursing, it's to do with your clone being active. If your clone is dead, you're free to hit other clones without issue. If your clone is alive you can only attack it or you get cursed.
