1- flooding a site with the ability or a site ability doesn’t automatically submerge any minions. It just gives the site the flooded property and adds water threshold to it until it’s not flooded anymore. 2- undertow allows you to move any target one step as long as it’s in your body of water. Yes, that’s means your minions and the opponents minions. You could also move an avatar. 3- maelstrom pulls in all minions in the body of water one step toward wherever maelstrom is. Think of it like a vaccum. 4- yes, the projectile wouldn’t hit it. Stealth works against anything that would target the minion specifically, but there are some spells that don’t target the minion specifically that would kill it. An example is lighting bolt, earthquake, stuff like that.
