Hy P. said: Lol - seems like when I quote someone it doesn't appear. Here are my questions: Whats so special about the 5th Edition OGL by Roll20 Companion? What is it exactly? Someone said: "Pro Membership for 9.99 will allow you to add API scripts to the game so you can do cool things like auto spell slot use, auto ammo use, and a variety of other cool effects." - what does that mean exactly? Is auto ammo use like removing an ammo when you attack? Yes. I use the companion and it automatically subtracts spell slots when I click to cast a spell. Also, it will reduce my arrows any time I roll for a bow attack. It makes the character sheet more customizable. They are really just perks though and depends on how many extras you want. I know some people that don't use APIs at all and stick with the Plus membership. It is just a matter of personal preference. As far as levelling up, it depends on what you have. If you purchase the Player's Handbook, your players can use the Charactermancer to easily level up. They will be limited to the races, classes, feats, backgrounds, and spells in the PHB though. Anything beyond that would have to be added manually. If you don't have the PHB, then characters can be created manually similar to how you would do with paper and pencil at a table, except you enter the data into a fillable character sheet.
