Am I correct in saying that Force Illusion allows you to block 1 source of damage (base, or base + modifiers) only? That is, you couldn't use 1 Force Illusion to block more than 1 source of damage (e.g., 2 base sides of damage)?
"Before attached character takes damage, you may discard cards from the top of your deck equal to that damage to block it. Then discard this upgrade from play."
