HOW DO you beat nijago act 1 lvl 6?

If you know how to upgrade your heroes then you make all heroes and research all upgrades at the keep before you attack and you get the bricks on the left and right side (the right side has 2 piles of bricks + there is a crack on the right side where you can build a mine) and also the red brick for regenerating health will help you (to activate red bricks you press pause and press red bricks then tap the circle next to where it says regenerating health) then when you have all of the heroes fully upgraded to the maximumest level they can have you go up the stairs on the right then keep going up then you will probably see a skeleton builder going up the stairs after collecting bricks from the top right corner of the lake in the middle of the map then follow that skeleton builder and that will lead you to the skeletons' hideout. Then keep attacking the skeletons with spells being casted by your heroes rapidly (don't use magic steal spell) first then when the skeletons have died start attacking the barracks' then the keeps because if you attack the keeps first then the barracks will create skeletons that will kill you while you are attacking the keeps so DESTROY THE BARRACKS FIRST. This help was for the DSIXL, DSI, DS Lite, and DS only and also maybe 3DS.

If you have unlocked the show enemies, use it. Then gather your army, then go attack them. If you don't have the show enemies on the map, build your army, then go out hunting for people (if they're bad guys,) then kill them.
