Proof

I used two squads:

Squad 1 - Mono Lightning - Twins Friend
Squad 2 - Mono Earth - 6* Lance Friend

I took Cure, High Cure, Divine Light, Earth Seal, and Thunder Seal with me. I used every single one.

I couldn't make a decent squad 3 because I didn't have enought Cost left over. Luckily it didn't come to that.

Both squads were running with one 6* leader and the Twins, so I had 50% ATK boost, 10% HP, and no status ailments.

The first squad got him to the Blue Execution moment, and were annihilated. I used about half the heals to get there. The first form was no problem, but his second form required some cures, especially since it was taking FOREVER to charge up Elimo's BB. Evil Shard would make this much easier.

The second squad killed him. At the end, I would come REALLY close to losing a unit before Tree's BB would fill up (need an Evil Shard). I would then put that unit on Guard and hope for the best. Luckily Lance's SBB charged up near the end and gave me a much needed DEF boost.

The transition from Karl's first to second form is pretty drastic interms of the damage he dishes out, but I didn't think he gets THAT much harder as you whittle down his second form. The buffs he gets at 10% or wherever weren't game changers.

I tried to take out Karl earlier in the week with weaker versions of these exact squads. The Lightning team didn't make it to Blue Execution so it was up to the Earth team. 2 of the Earth units who weren't guarding died during the Execution, so I figured out pretty fast the first team would need to get me there.

Key Points

• Plan to lose a squad at the Blue Execution moment
• The Twins are very helpful
• Use Evil Shards on healers if you can
• Use Defensive Seals
• Guard with attackers if their HP is low and healer's BB is a few turns away. It'll save you cures
