Glorious Annals of Lodoss Challenge #5 - Langrisser Mobile
The last challenge of the current collaborative Lodoss event.
I got cocky in the middle and accidentally nuked my Rozenciel to death with Yulia's heal... (Frozen units got damaged when they were healed).
But well, the main gimmick of this one is that, you wanted to kill Deedlit fast. But in order to do so, you would need the debuff you get from Parn's skill to purge you of the "Frostbite" debuff from Deedlit. Furthermore, if one of them dies, the remaining one would get their skills' damage boosted by 50%. So in the end, you will basically have to spread your damage equally between both of them during your run, so that you can kill them both around the same turn at the end.
You also have to pay attention to keep at least 1 unit inside Parn's and Deedlit's attack range all the time, unless you wanted to get hit by a catastrophic whole map AoE. It means, you couldn't avoid getting hit by their skills, and getting their nasty debuffs.
I wish you good luck and success.
