DM Tried to tpk should I feel some sort of way about this?
Last session a player in our group had opened a spirit box from a merchant one of our players wasnt paying attention during the whole scene about how the box was dangerous and that he was getting rid of it for cheap and the guy wanted it after so he bought it without paying attention to any of the downsides that were mentioned. and our dm rolled an Infernal ancient Blue dragon on the encounter table. We are level 5 so there was no chance to win it was going to be a chance to run and likely die. I am a wizard and had all my level one slots and a level 2 slot. At the end of that session I had mentioned my plan was to cast invisibility and use my winged boots to fly so i would't leave tracks. So the next session came along we all rolled Initiative and I rolled ahead of the dragon so I casted the invisibility and flew. On the dragons turn the dm says he has unfortunate news that the dragon has true sight and he even told another player that it had it before session laughing about how my character is dead cause of the truesight. So when this came along I was suprised and it felt a little targeted but i kept playing. In the end my character ended up dying so I was kinda upset but I waited til after the session to look into the statblock just to see and found out it did not have truesight. So im a little frustrated cause I understand changing statblocks is well in the dms ability but it feels a little targeted and that he just changed it to give it truesight specifically to counter my plan. Should i feel a certain way about the dm in this situation it just feels a little targeted. And in previous sessions i had been heavily targeted in most combats. Sorry for the bad grammer just kinda typed this up pretty quickly. any thoughts would be appreciated.
