I understand that if I use Study of Enemies on my attack target, the damage of the attack will not be modified by due to timing (Step 5 can't affect Step 4)

If I use Study of Enemies on a target adjacent to my attack target, will the Battle Vision adjacency damage bonus apply to the attack target?

I'm guessing yes because Battle Vision's timing is while attacking, but would like confirmation.

Thanks!

"While attacking" really means "at the appropriate time during the attack." Battle Vision adds a damage so occurs at step 4.

@a1bert made a (I believe) complete listing of what occurs when: https://boardgamegeek.com/thread/1631857/ability-resolution-order-during-attacks

Have you checked https://www.boardgamegeek.com/thread/1631857/ability-resolution-order-during-attacks ?

Battle Vision triggers on step 4. If you use Study of Enemies on step 5, you don't get the bonus from Battle Vision.

I wasn't aware of this list, will have to check it for everything starting now!
