From the start, traps are useless because invaders always dodge them. I even made this ten room long hallway of traps, and they just dodge every single one.When they get to a servant or the keeper, they always one shot in a single turn and I struggle to deal even 10-20 damage to them. Even after a dozen hours of trying on the same file, losing every fight, I still can't figure out what the fuck. When I finally do manage to kill someone, it's by using tons of consumables/bombs to just kill them outright without combat, and their body costs millions of blue points to ressurect, or I can sell it for millions of gold? Why am I only getting attacked by legendary super heroes basically?

Unfortunately, the way that the changes to enemy level works, this means that once your keeper's level is high enough, you will exclusively get busted-hard enemies that always spawn with mastery of the weapon they're using, legendary weapons, and a billion quick draws that allow them to decimate quite literally any character in the game, regardless of level unless you cheese them with stuns and/or items. This also makes the "Ancient Warrior" start nigh impossible, since the keeper starts at a much higher level than the others. My only suggestion is to use one of the other starts and try to avoid leveling up your keeper as much as is humanly possible.
