How to Complete A Step Further
The objective is to protect Ocktor Mack and defeat all foes. Solitude is forbidden, meaning that at the end of your units' turns, they have to be next to at least one other unit.
If one of your units attacks an enemy unit and knocks it back, your unit could unexpectedly end up not next to any other unit, so you might want to only use magick attacks to avoid this, and you might also want to avoid using Counter and other damaging reaction abilities.
If you are planning to obey the law, your units will be more vulnerable to area-effect spells because they will all be next to each other, so keep that in mind. To reduce this risk, you could try to only stay next to enemy units when possible.
Ranged weapons and magickal attacks could help the battle end more quickly.
