This spell let u collect still-alive troops on the battlefield and u can use them again as haven't deployed troops (but only in this battle) and the hit point within each kind of troop is averaged so u cannot get more health. At lvl 1 it collect 30 housing space of troops in its 4π area starting from the least expensive troop(if still cant decide then the troop with most health and if this still cant decide, meaning same health, then the one nearer to the centre). Lvl2 35 lvl3 40 ......and sorry for my poor english and comments welcomed
