Damage Calculator Tool

Ranulf and Lethe Strategy

Use a Bulky Green Unit For the Left Side of the Map

Enemy units on this map will not move until you enter the danger zone.

Use a bulky green unit and move them to the space on the left to take out the Blue Mage and Ranulf.

Approaching from the right side of the map could prove dangerous as the Lance Cavalier has Lunge, which will force them and your unit to swap positions, making them open to attacks from the rest of the enemies.

Use Tome Users Or Units With Beast or Cavalry-Effective Weapons

Brave Lysithea

Picnic Felicia

Yarne

Julian

Both Ranulf and Lethe have low Res, so using tome units will be extremely userful. Alternatively, you can use units that have weapon effectiveness against either beast or cavalry units will also work.
