I tried to look for it but cannot find it. Please help!

So this was my first campaing. I did not know you could use legacy points to reduce enemy cards. Now I have 14 spare legacy points. Sadly every battle is a bossbattle now. I am often faced with several bosses in one battle. I simply do not have enough damage output to take them down. It was fine, until the end of chapter 2 of campaing. Then it just spikes up, the difficulty. Basically it becomes unbeatable. I do not have resources and cannot craft weapons. XD I got 1 decent warrior with T1 weapon. The rest...

Will the other player than join will focus only to control character in battle, or the other player will also able to choose/affect the story?

Is there a known culprit?

I like to play my campaigns as if they are all on the same timeline, so I prefer for my legacy characters to stay the same when they’re recruited into a new campaign. This last campaign, I had recruited a legacy mystic and completed the first act. The second act, I recruited that mystic’s father, a warrior. Because the game resets a legacy character’s age when you recruit them, the warrior ended up 10 years younger than his daughter. Is there any way I can change this with dev tools or through mods?...
