Interesting. Because you were doing too well? The only way KD:M gets a little boring to me is if I'm trying to min-max and only fighting the most appropriate monster for maximum return at each twist or turn. All those underleveled lions for 15 rounds, then all those antelopes, avoiding phoenix and any unique monsters, etc. I did a playthrough where I suicided extra population against most bosses instead of risking my better ones. Ok, that can get boring.

But throw all those in? Nothing quite like going for the overpowered unique phoenix and trying to land his death bonus on my character with Immortal disorder. Also nothing quite like that character making it, then constantly being targeted with "instead of damage, roll on critical injury table" and having to blow my party's rerolls to save her. (For the record, no she didn't make it to LY30)

But honestly, to each their own. I really enjoy it. And adding a few more hunt or showdown monsters (when you really "know" your base prey) is enough to keep an entire campaign fresh. And if not, PotSun and PotStars is a blast (said in Tabletop Simulator because I can't afford all that)
