Magick: the Refluffing Edition
>Pastebin (Expanded with more resources!)
>Frequently Asked Questions:
>What is Essentials?
An attempt by Wizards of the Coast to try and simplify the game and make it easier for newer players. An interview of Mike Mearls talking about the 4th Edition Red Box can be found here: https://v1.escapistmagazine.com/articles/view/video-games/columns/writersroom/8115-Complete-Mike-Mearls-D-D-4th-Edition-Essentials-Interview.3
>What's wrong with the Math?
It's kind of fucked in the first couple of books. The Monster Math from the Monster Manual 3 onwards is a lot better. Essentials keeps this trend and also has better math for Skill Challenges.
>How do I get started?
4e is more or less a finished game, since there are no more supplements planned for it. If you're a Player, you can't go wrong with picking up the Player's Handbook. Be wary that there is Errata online, however. For Dungeon Masters, the mandatory books are the DMG and DMG2, which both give great insight into DM'ing, and aren't simply a handbook for creating encounters and adventures. I'd also include the Dungeon Master's Kit from the Essentials Line, with it having the fixed Encounter Building rules. The Rules Compendium is another great product.
Why use 4e when you can play 5e or some other game instead?
Tell us of ongoing campaigns. Journals, notes, planned and done encounters, anything you got.
