"Oh, I almost forgot I had this."
He suddenly realized.
[Doram Ship Cannon Signal Flare]: Deals 1000 points of total damage spread across all enemy cards at the start of the game.
So, he saw a bunch of numbers pop out amid the explosion and flames.
-100, -90, -90, (Invincible), -90, -90…
"Eh, so I basically just cleared the first stage like that."
At this point, Ree Shil fully understood.
There are 10 opposing cards, 1000 points of damage spread evenly across them means 100 points of damage per card.
Then, under the influence of [Doram-Class Ship Flag], [Doram Spirits] takes all the damage -10.
But [Doram Spirits'] health is just 90 points.
He heard from Secretary Brown that in rare cases, some spell cards specifically counter the boss in this level, like [Doram Ship Cannon].
At the time, he thought those spell cards might be rare but useless, as they only countered bosses in this specific Instance, and they'd be useless in other Instances.
