GM/DM Help

Welcome to the GM/DM help thread. GMs and DMs, new and old, ask your questions and may they be answered.

When is a DMPC ok?

When you realize that you didn't properly modulate the difficulty of the session for the party (say, if your healer canceled last minute in a trap filled maze).

When the DMPC is actually the BBEG in disguise.

When you're good enough at writing and portraying the character that your players enjoy having them around.

Never.

Just don't give them the best crap, don't let them outshine the pcs and do things they can't, don't let them be the hero who lands the final blow on the villain, don't let them railroad the players, and don't make them the leader. That's about all I have for now

When your party is ok with one.

How do you get better at dialog?

Seconding this

how do you mean? like writing it or actually talking as the character

Define "better at dialogue". What is the specific problem you are having?
