You can check your ninja's life, attack, ninjutsu, and resistance in the 'Character' menu. There is also a *on with the title 'Details' that you can click on to see more in-depth of your character's stats. You can get the pages for tactics in the shop, they sell for relatively cheap for 25 coupons each. As for lineups if you can reply with all of your ninjas and summons you currently have, maybe I can help create a decent team for you.
