I can't remember if this was asked already, but I'm pretty sure I saw this at one time. Just can't find it on the search. Can you use Defend on your turn or in any turn in particular? And can you turn it on and off whenever you get the chance?

DEFEND Any adjacent friendly character may replace its defense value with this
character’s unmodified defense value.

As long as they are adjacent to the Defender, they may choose to use their unmodified Defense value. *shrugs*

Anytime there isn't a stated restriction, these kinds of replacement values can be used and checked whenever they would be called into question.

Just out of curiosity, what is this scenario?

Dr. Thomas Wayne has both Defend and Support. Was wondering if it's legal to use Defend on my turn to lower an adjacent friendly defense, and then hit it with Support. Then after action resolve, the adjacent friendly can get back his original defense value.

That's all perfectly legal.

Yes you can do that. I do it all the time with hired henchman.

Thanks a bunch guys! Wasn't sure if that was changed

how long last defend???
say that i use the defend/support combo but i get a 3 in my dice roll, my character will have the remplacement defence value until he is healed or damaged, or i can choose to use or not use the replacement value????

T B . . . . . . . . A

T=Thomas wayne
B=Batman
A=Alfred
example if i have D/S combo character (thomas wayne) and use defend to reemplace de defence value of my batman to 14 and fail the support attack roll.
my batman move 8 square to became adjacet to alfred,

can alfred use the 14 defence value previosly reemplaced or it will use the original defence value???
in case that nobody can't heal batman after the use of support, batman can choose to use his original defence value or it will use the 14 defence value until he is damaged or healed??

The value is only replaced during the attack (roll). There is no change when the person being defended is healed or damaged.

Not to mention fun!
