There might be a thread to these questions I am about to ask however i was not able to find them so forgive me if one exists already.

So here are my noob questions on defense.

C
B A D

X= Super Senses, Toughness, MAstermind, Invincible, Impervious and Invulnerability.

Hero A is surrounded by their opponents units; B, C and D.
Hero A has X.
B does close combat attack.
Hero A uses X and resolves action.
C and D now attack A as well on their respective turns.

My question is when a new unit Attacks A can I reset my defense ability (X) once the attack from the other unit (B) resolves ? Or do i just use a defense ability one time and pray the other unit's attack miss?

Now if the answer is yes I do reset it, If A was attacked by an attack move like Flurry, or any move that makes a single unit attack TWICE , can i use my defense ability ( X) twice or just once?

I literally have no clue what you are asking.

Shape Change Can be used with Any Defensive Ability.
Master Mind Can be used with Any Defensive Ability.
Super Senses Can be used with Any Defensive Ability.
Toughness CanNOT be used with Invulnerability, Invincible, or Impervious.
Invulnerability CanNOT be used with Toughness, Invincible, or Impervious.
Invincible CanNOT be used with Toughness, Invulnerability, or Impervious.
Impervious CanNOT be used with Toughness Invulnerability, or Invincible.

No one ability can be used multiple times. So if you have Super Senses from two different Sources you can only use One of those Sources (only one roll to evade) Per attack.

Every time you are attacked your defensive abilities trigger, unless the attack itself specifically says they do not (IE Pulse Wave).

If you have a Power or Ability on your dial/card no other source can give you that power/ability even if the original Power/Ability is an altered form or if the Power/Ability from the secondary source is an altered version of the Power/Ability. Meaning if you have a Power That says you can use Super Senses, but only succeed on a roll of 6, and you use a Resource that says you can use Super Senses and it succeeds on a roll of 2-6 when you are Attacked you must use the version you character originally had and would need to roll a 6 to succeed.

I hope this helps.

You choose your abilities each time that you would use them (meaning when you would take damage, you choose which one you use). Super Senses works on all of them as that triggers off of when you're hit (which is before damage is dealt) so you could SSen, then choose to either Mastermind to an adjacent friendly (of a lower point value) OR reduce the damage via any of the powers listed (but only one).

I'll use your example:

C attacks A with a Close-Combat attack.

First, A uses Super-Senses to determine if the attack hits.

He fails the roll - now A chooses which power to use (he can only use 1 per the rules as the remaining powers either reduce , ignore or place damage somewhere else).

He chooses impervious. Rolls for Imperv, fails that roll and reduces damage by 2.

Next, D attacks with flurry. D makes a successful attack roll. A uses Super-senses to see if the attack hits. He makes it and the attack misses. D makes his second attack and hits. Again, super-senses kicks in and he rolls to see if the attack hits. He fails the roll. A then chooses Invincible to ignore half the damage.

Next, B attacks with Exploit Weakness and rolls high enough to hit. A uses super-senses to determine if the attack hits. He fails the roll. Next, seeing as there is no one to mastermind to, and EW will cut thorough the damage reducing powers, A opts to use Invincible again to ignore half the damage .

I hope that helps.

... sorry for the confusion ... Let me try to make my self clearer. I am basically asking if i have a Hero that has ONE of those defense abilities (X) does it basically only apply to one opposing unit or am i able to use it for all units when it is their turn to attack... so lets say that X is super senses. B attacks i roll a 5 or 6 i evade.... Now when C attacks the question at hand is may i roll super senses again?

OMG yes you did... thank you so much man from the bottom of my soul!

Ah. Much clearer. Thank you.

You can use powers and abilities every time they would activate. So if you are attacked 100 times in one turn you could use Super Senses 100 times. The same goes for all other abilities you mentioned.

Just note, that you cannot use the same power AS A FREE ACTION more than once in a turn.

None of the powers you listed are free actions. They all work off of trigger events.

Sir dragon thank you so much!! You da bestest 100 times over!!

There is no action to resolve when using "X". X, in you example would be a special power granting the use of multiple standard defense powers. None of these are activated by an action, but trigger each time this fig is attacked.

Also keep in mind that you can not stack powers that ignore and or reduce damage. But each time you would be dealt damage you can choose which one you would want to use.

Thank you disciple of JC ! :}
