I am A new DM who has just started DMing a game of LMoP - this is my first game in which im DMing. There are only 2 PCs right now. There is a 3rd PC who comes to play on-off. (Is this ok?)
I have been Thinking of adding a NPC to the party to replace her when the 3rd PC's not there.
Another problem I have is that one of the PCs (Fighter) IS extremely bloodthristy who will do anything for that Sweet xp. The Fighter is recklessly running into combat without thinking.
How can I get them to stop being Bloodthristy without ruining their fun?
My last problem (which is a minor one) is that we have arrived at a small river which we need to cross. Our Wizard used Ray of Frost to freeze the river and cross it. I allowed this. (Is that ok?)
Should I have given him an Inspiration point?
