If a character gets hit for 3 damage and hits a stop click after 1 or 2, would they still have taken 3 damage to activate an indigo tribe compassion action like:
COMPASSION: REDEMPTION: When a non-adjacent friendly character within 6 squares takes 3 or more damage, after actions resolve, if that character hasn't been healed this turn, you may place Sinestro adjacent to that character and heal that character of 1 damage. That character can't be attacked again this turn even if this power is lost.

Thanks

No. Damage taken refers to the actual amount of times the dial is clicked.

I'm not totally sure if that's the case. I thought I remembered reading somewhere that they still technically took the full 3 damage.

I would think it would be the same as Toughness, for example. If you're dealt three damage, you only take two. As such, I think Nordles got it right. But, I mean, if there's evidence to the contrary it wouldn't be the first time I'm wrong.

I think damage dealt is the damage you get hit and damage taken is what you clicked/turned the dial

What Daffy said I believe is correct. Damage dealt is the full number; damage taken is the actual number clicked.

To clarify, if the Compassion power read "When an opposing figure deals 3 or more damage to a friendly character...," it would work regardless, right?

Or maybe I am crazy, wrong, and confusing the issue even more.

Nordles is correct.
