Kalentia, move three squares to the left.
Eyr, move one square down.
Rohey, move one square to the left.
Renold positions himself to the right of Kalentia.
Veserod positions himself to the right of Ren.
Ilva positions herself to the right of Veserod (below Eyr).
Meanwhile, Alessia first uses the fire rune at the bottom. On the next turn, she moves two squares up, and then casts the rune at the intersection to burn the third ore golem. After the bottom rune detonates and the new one is cast, she moves slightly down into the tunnel to get out of the range of the upper rune. After that, skip until the upper rune explodes.
If there are no mistakes in the sequence of actions (there shouldn't be), then proceed.
