A spell that attracts your entire army. I.E. if spell is casted in the middle of the base all attackers will gravitate toward that spell for 25 seconds or so. If a giant has the option to go left, right, or forward, and there is a defensive structure 5 spaces away next to the spell, it would choose that structure instead of the structure that is 3 spaces away to its left. There would likely be a spaces limit. i.e. the spell is ineffective if the structure inside the spell is more than 7 spaces away. This would help gravitate your attack to the nucleus of a base and give you greater control in planning attacks instead of just hoping they go the way you want them to.
