Some things to keep in mind for a first time player
1. There is a max total of four you can have in a party (including your two main characters) many of the puzzles will require the placement of party member.
2. There are a total of four companions you can recruit. a mage, a ranger, a warrior, and a rouge. Something to keep in mind when building your party.
3. Every speech check is determined by a rock, paper, scissors battle. If you find that annoy there are mods on the nexus and steam workshop that get rid of that feature.
4. Choose the star underwear during character creation.
