I've decided to create my own DM's guide. Atleast in my spare time (which has been rather non-existent lately). This idea formed in my head after reading and commenting on this blog post http://drbargle.blogspot.ca/2015/06/more-on-reaction-roll.html
I intend to use the B/X reaction roll running 5e. There are also a plethora of awesome tables out there that would be perfect to throw in as well. Basic Fantasy has a ton of great tables, this blog is awesome http://roll1d12.blogspot.ca/
Along with some tables from my 2e guide, I also plan to create a few lists of NPC names using generators.
Microlite has a super stripped down essential rules that has a great set of traps with DC's. That'll go in there.
Yup this was a random post....
Just an idea I've been kicking around, something quick and easy to look up. A few notes on 5e stuff as well.
