TGT said everyone gets a reaction, and that was one of the options. That's what I plan to do myself, to minimize risk.<br/><br/>I have a 1/3 chance to dodge the grenade, followed by a 1/2 chance for the field to protect me. However if both fail, I'm taking a<em>lot</em>of damage. Cover takes off 8, with toughness bonus that's 12 total for 5 wounds potentially instead of 13, and I still have a 1/2 chance to negate it.
