JOKERFISH: Once per turn as a free action, the Clown Prince of Crime can put a Jokerfish token (a SPECIAL token) in an unoccupied adjacent square if there are fewer than four Jokerfish tokens on the map. At the beginning of your turn, if an opposing character is in the same square as, or adjacent to, a Jokerfish token, you can deal 1 damage to each opposing character in the same square as, or adjacent to, that Jokerfish token and then remove that token from the game. Remove all Jokerfish tokens from the map if the Clown Prince of Crime is removed from the map via the He's Escaped Again! trait.

My question is are the Jokerfish tokens considered blocking, hindering terrian or niether.

it is neither it says in the power that they are SPECIAL tokens. SPECIAL tokens or not blocking,hindering or any other terrains. It marks a square that something is in like with laz pit.

Does damage from muliple Jokerfish stack or apply one at a time when dealt?

I would assume it is like poison and would be one at a time. Damage is coming from a different source for each one.

It is? I thought it was all coming from the Joker. (or CPOC)

yes they would be from different sources that originated from CPoC.

But as i said this is my belief but i may be wrong.

Not going to start a new thread, so hopefully necrocizing this would be okay:

Blades/Claws/Fangs cannot be used in conjunction with the bolded part above, correct?

1-8 are opposing figures, all with 16 DV
J is Joker

123
4J5
678

Assume I'm doing the "target all adjacent opposing characters," so the Defense Values of #1 would be at 16, #2 would be 17, #3 would be 18, and #4-#8 would be 19.

Correct? Thanks!

Since it's characters adjacent to him, I think it'd be +3 to all their defenses, only because the rule of 3 doesn't allow it to be more. You've got 8 adjacent foes, so even if you don't count #2, that's still 7 adjacent characters adding +1 to the defense of #2 (not to exceed 3, totaling 19D). That's how I'm reading it, at least.

First question, you are correct, Blades can only be used during close combat actions, not attacks.

The second one, the poster below you is correct, they all get +3.

And he rolls for the special Incap with ONE ROLL, correct? Not one roll for each opposing characters?

Correct. It is one attack with 8 targets.
