This is what Wil Wheaton said about these Lava Rules: "My motto in gaming is 'don't be a dick' and nothing leads to dickish behavior faster than a rules disagreement. Thanks to Fire and Brimstone: Guide to Lava, Magma, and Superheated Rock players and DMs will never have to argue when resolving encounters with lava. Or Magma. Or Superheated Rock."
And here's Peter Adkinson: "Back in the early 90's, while at Wizards of the Coast, we published 'Capsystems' like The Primal Order for using a set of rules with a variety of game systems. Then in the late 90's, came d20, another attempt at unifying RPG rules. But these rules on lava are the most elegant cross-platform rules yet, taking the philosophy of cross-system play to a whole new level!"
Finally, Gary Gygax: "This is a breakthrough in determining a long burning question of great magmatude. I plan to institute this comprehensive rules coverage in the Lejendary Adventure game!"
So, with all that praise, I just had to use these rules. I hope you all understand.
