I'm fairly new as a DM. I just start to playing 4D (and D&D for first time) last year, just like my PCs. Becuase it was my first time DMing and it is a big group (6 PCs sometimes 7). At first, I had some trouble making proper encounters and challenges to keep the game interesting.
I started running published adventures just to learn to how play the game, and after the second adventure, I took the risk of making an Open world long term campaign. It worked. My group always prefered PC story development over just random encounters. So it was easy for me to know what to offer them, but my lack of experience made me too flexible with the rules making the game too easy for them. I tried to fix it taking the rules more seriously, like no more flexible DCs (just when it was needed). They like it.
Still at this point the game sometimes felt like slow-paced, sometimes because the encounters were really difficult for them, or because everybody wanted to do something different. So I start pushing the game, putting some pressure on the PCs, making the encounters smaller but memorable.
...long story short.
Because we don’t really play that often (once a month), I have time to prepare the game. So this last encounter I did this epic fight with a Demon who possessed one of the PC and destroys a village, so the other PCs decided to kill him to stop the Demon. So yeah... now he is dead. I didn't expect that. After the game they asked if there was a way to revive this PC. I was planning to send them to the underworld to try to rescue his soul or something. I would like some help here.
Oh and another PC lost his “off-hand” arm in the fight. A this third PC ended with his back broken. I've been reading about permanent injuries in game, and how they can affect the mechanics. This was planned but the PCs (again) reacted in different way and now one of them wants a magical prosthesis and the other one wants to take "vacations" (yes, ingame) to heal his broken back. I just did it to give it a more violent, dark and serious touch to the story, now I need to offer them some options for these.
What do you think or permanent damage on the PCs and how do you deal with a dead PC who didn't what to die?
