Kris, the 6th Determination card and 1st DT card from Deltarune, was added in Beta 30.0. Previous Versions can be found here.
Card Skin (Kris)

Dark Knight

With Kris on the board, your entire team will power up with each attack, giving the attacking monster +1/+1 for each other ally monster on the board, with a max of 2.

Keep in mind that Kris doesn't benefit from this effect itself, but since it will count towards the needed other monsters, any of your other monsters that attacks will get +1/+1 or +2/+2 before the attack hits its target, dealing more damage and be more likely to survive the counterattack.

This makes Kris a perfect support card, and due to it being Determination, its effect can't be silenced either.
