I wonder, if I discard e.g. 20 cards from players deck through one single effect, does Kraken Tattoo give attached character 20 STR and 20 Intimidates (because I would trigger its response every time the single card is discarded)?

Rudeman said:

Well, the timing is off in the way you worded it; the response on Kraken Tattoo can't be triggered until the discard effect has fully resolved and all cards have been discarded. However, it can still respond individually to each card that has been discarded by the effect, so you can get your 20 Str.

Thanks, maybe I described the mechanism of triggering response wrong a bit, but the final effect is as I espected

I was just concered about legallity of this nice effect.
