Many things were wrong in curse of Strahd campaign I participated in a few years ago. This post will only focus on the part that made me officially quit because my original post was too long (there were many problems in that game) and got removed by reddit filters. I wanted to share my story.
I was desperate to play this campaign and play as a player back then. I find a guy on facebook for a game on roll20. Weirdly this guy banned wizard from the classes. I joined, made a dwarf light cleric of Lathander and the guy forces on my character a curse before the very first game.
Basically, each time I would use an "offensive action" (he actually said an attack but he started forcing to roll when casting offensive spells), my character would roll a d10 and if I hit a 1 or 2, my character would become "paralysed" for the rest of the turn (I had 20% to lose my turn, like a worse and permanent version of the concealed condition in pf2e).
I reluctantly accepted at the time because I was desperate like I said. That was a big mistake. I believe that he was a good storyteller, but a bad dm for the game.
Fast forward to the first vistanni camp. The dm used Madam Eva to tell me how to get rid of my curse. It was a greater restoration spell, remove curse wouldn't work.
Fast forward to the Gulthias tree after a year. We were led to their lair in underground tunnels beneath the tree. The druids asked to be left alone and were willing to exchange a cure for my curse. I thought I had an important choice between choosing the cure at level 7 by making sacrifices or wait to level 9 to get greater restoration. I accepted.
Then happened the final nail in the coffin. The dm made my character sign a blood pact which could lead to negative consequences and all he told me is that the cure was sap from the tree + a root + greater restoration. I immediately confronted him because that's not what he told me a year ago. I had to sacrifice a lot because of hopes to get a cure early and I gained nothing because the dm decided to add new roadblocks and gave me a false choice. He just said in a mocking tone, "Maybe Madam Eva didn't know everything". I endured that curse for an entire year. If my dm was lying to me like that, that moment broke permanently what was left of trust.
I was planning to leave the game after we destroyed the tree. I was thinking about leaving for a while because I kept feeling stressed when playing the campaign and I didn’t have much fun anymore.
