ok im confused now...
toughness, impervious, invulnerability, and all those defense super powers are great. but sometiems i hear they can only stop certain things.

for example... does posion not work against any of those?
what about energy explosion? or pulse wave?

how can you tell?
please help!

Invulnerablity and Toughness will reduce damage from any attack or any power that causes damage (with Psychic Blast and Mystics team ability ignoring this).

Impervious will allow a roll to dodge all the damage if this figure is being directly targetted by an attack. If succesful, this figure will take no damage. If failed, this figure will reduce the damage received by 2.

Poison is a super power that causes damage that does not target.
Invulnerability/Toughness works on super powers that cause damage. Impervious will only work on those attacks that directly target.

So, Poison would be soaked by Invulnerability/Toughness... and would totally go through Impervious.

Is this enough? or more?

Poison works against Impervious, because Impervious only triggers when the figure possessing it is the target of an attack. Poison is NOT an attack, so it goes right through Impervious. Poison CANNOT be stacked, so it is negated by Toughness and Invulnerability, both of which reduce ANY damage applied to the figure, Toughness by 1, Invulnerability by 2.

EE splash damage, again, goes RIGHT THROUGH IMPERVIOUS, because it is splash damage and not a direct targeting. Again, Toughness and Invulnerability WILL reduce splash damage. The same applies for Pulse Wave.

DANG IT TSANNIK!! Get a real job or something and stop beating us all to the punch!

ok thanks. i think i got it figured out now.
