This is a group I'd been playing with for years.
>DM is always super harsh on rules, prides himself on being the players' enemy
>lots of player death so we adapt, never felt unfair or targeted
>one player makes a character that puts out a shit ton of consistent damage, makes encounters easier
>not trivial mind you, just not lethal most of the time
>DM clearly gets angrier as we go without character deaths for session after session
>monsters start targeting the damage dealer despite him staying on the back line
>characters start dying as encounters ramp up
>but I'm playing a cleric, always make sure to revive characters now that we're high level
>eventually reach a boss-style enemy, supported by an army and a half dozen spell casters
>just so happens that my cleric, and damage dealer were down, but stabilized as we fi wished off the battle
>DM has the two surviving casters ignore the barbarian, sorcerer, and bard polymorphed into a dragon in their face in to hit the pair of us with four magic missiles each
>destabilized, three wounds, instantly dead
And immediately after, I'm shocked to hear he's been talking about kicking me and the damage dealer out.
