My brother asked me about this, and I couldn't answer this cuz he started to confuse me....How does shape change work...

"When this character is chosen as the target of an attack, roll
a d6. On a result of 5 or 6, the attack can’t be made and the
attacker cannot attack this character for the rest of the turn.
If the action becomes illegal, the attacker must choose
another legal action to perform, if possible. The selected
action must be a free action or non-free action based on what
the action type was given to it that led to the attack."

He was asking me if cosmic spider man uses TK and misses can C.S use his special power, Psyhic webbing adn use force balst, once a player rolls a 5 or 6? "opponent rolled a 5.

If they make their Shape Change roll of a 5 or 6, then they cannot be the target of any other attack by that figure for the rest of the turn. Your other figures can still attempt to target them with an attack, and you can target them with Perplex or Outwit too.

He could use the Force Blast, but he could not then use the RCE that it grants since it is an attack.
FB is not an attack.

Cool, thanks for the clarifactation, i knew about free actions, but the non-free were confusing..thanks again
