hiyo, i could not find a definitive anwser for these questions
first question: does the smoke cloud ability from raam:

(TROIKA BLASTS AND CLOUDS OF KRYLL: General RAAM can use Penetrating/Psychic Blast. Once per turn, if General RAAM has no action tokens he can use Smoke Cloud as a free action until the beginning of his next turn. At the end of your turn, roll a d6 for each opposing character occupying a square containing a hindering terrain marker placed by General RAAM, and on a result of 5-6 deal the opposing character 1 damage.)

make raam take mystic dmg?

second question: does the dmg from ink grenade, at the beginning of your next turn make raam take mystics dmg?

Ink (1 penetrating damage): Place a hindering terrain marker in the target square. At the beginning of your next turn, deal 1 additional penetrating to each character occupying the target or adjacent squares, then remove the marker.

First question: No, becaue the damage from RAAM's Smoke Cloud power does not come from an attack.

Second question: Again I think no because, while the initial grenade attack would trigger the Mystics TA, the followup damage is not dealt directly from an attack.

Neff is correct. Mystics only kicks in thru succesful attacks. That's why Poison is so effective against them.

thanks for the help guys
