-First part of mission involve safely escorting Spirits to kill the first ward. 2nd part of mission involve killing Summon Gates and bosses. -Move up to intercept and kill mobs north of your base before they engage ally spirits. Start heading south afterward. -Don't get caught by net trap little south of your base, or it will get nasty. -Ally spirits do suicide attack on enemy mobs (and deal a lot of damage). But don't let too many of them die, or you won't be able to kill the first ward. Clear mobs so that spirits won't waste their lives on stray mobs too much. -Once the first ward is down, go cross the bridge and destroy 2 Summon Gates. -As you go near 3rd Summon Gate to the right, a boss will come after you. Kill him and proceed -After Cut-Scene, 3rd Summon Gate activates and spawn mobs and rate of 4 mobs every 2 turns. Make sure to kill it asap. -You will face large group of mobs when you move to upper part after killing Gate. They always come in lines/clusters, so have fun killing them with AoE/Gun/Cannon. Boss will also come behind them, so be careful.
