Rumi is teased by Peter and Thanatos for their 'sex cult' after they woke up in abed w many people after getting drunk. This is not serious or mean-spirited, just a goof.
There is no "i'll kill myself" but sometimes when Peter is talking to someone he'll self-deprecate and say "or i could die, if you want." This is not portrayed as serious however.
Rumi is a changeling, and talks about how he doesn't really know who they are, and that he's lived many different lives and yet they haven't truly found themselves.
It is a DND podcast so the fourth wall is kind of thin, the characters will often say something non-canon as a joke and sometime during the finale another character from a different campaign on the podcast is brought in non-canonically for a bit.
There is a scene where the main characters are drunk and go on a drunken rampage, and have pretty bad hangovers in the morning. It is rather light and not serious alcohol abuse.
I don't remember which episode but after they all get drunk Thanatos does kill a bunch of bears and exandroth a bunch of fish and stuff. There's also Peter waking up surrounded by dead animals, and killing the wolves
They do kill some animals although aside from maybe episode two there's no graphic descriptions. Aside from what Thanatos did to the bears though that isn't in gorey detail
Yes, one of the people that the party killed is mentioned to be "reliving the moment of his beheading for 30 years" mentally, and Thanatos is rather violent in the first few episodes which could be considered torture in many cases.
Exandroth, the archangel of retribution is possessing Peter Sqloint and often takes control of him against his will. It is mentioned that this hurts, a lot.
