Thank you both for the support and the advice. I have been trying to figure out where I should start and planning things out. Honestly it is a bit daunting but the main things I need to figure out are how to write quests, create items, make objects conversible, and where I want to put the amulet in the world. I'm not sure I have the skills to make my own dungeon so I will likely need to use an existing one. I'm thinking a crypt in the graveyard district at the moment.
pro5 I think the plot line leading back to the amulet is an excellent idea. I will work that in once I puzzle out how to actually write quests. I have some outlines drawn up but I'm not sure where to start or what kind of programs work best for this kind of thing. I am very new to this but I'll get it done eventually.
The second suggestion is also doable and I can keep the paladin out of the party. If its possible I want Braxas to be only visible to the player in the later stages when he gets the strength to leave the amulet for a limited time and kind of like a seventh party member. He is there but he is only visable to the player and I'm still deciding what kind of abilities he and the amulet should grant....Suggestions or ideas are welcome and this is still in the works just slow going to start with.
