Lethe's Caress and different attacks?

[SirFoobar]

This may be obvious, but I am a bit unsure if I got it right, so I will ask anyway

Lethe's caress requires the opponent to do the same action more than once to trigger. As far as I understood, the different attacks are considered different actions. So using two different e.g. melee attacks in the same turn should not trigger Lethe's caress. The same should then probably apply to using two different tactical actions in a turn, right?

Yes, if a specific action happens twice you take damage, but something like moon shineobi with 2 different melees can use both without proccing Lethes, however stuff like onslaught automatically net you a Lethe proc cause it's done twice
