For sure, taking breaks is important if I get frustrated with a game. Fortunately enough the only boss to truly stump me so far has been Commander Gaius. I eventually summoned 2 of my friends and the fight became a lot more fun, but even with 2 other people it took us probably 15ish attempts due to the massive health increase caused by summons and I’m also on NG+. I’m sure the final boss will be tougher, since I’ve heard from everyone who crazy it gets.
I’ve been better about my pacing this DLC, too. When the game initially launched and I binged it for about 2 months straight and was super burnt out by the end (had a lot more free time back then due to COVID and only 1 kid).
