()||10:These are rules of this battle. //n1. The map is divided into two kinds of nodes – those marked with "↑" and those without the mark. Nodes marked with "↑" at the start of the battle will never lose the mark. +2. Stepping onto a node marked with "↑" gives you access to the nodes immediately adjacent to it, while stepping onto a node without the mark makes its adjacent nodes inaccessible. +3. Upon stepping on a node without the mark, that node and its adjacent nodes will gain the "↑" mark. +Attention – Switching Echelons around will trigger changes in both nodes occupied by your Echelons. Please use this function at your own discretion.
