1d20 Oracle Bookmark

Inspired by the 2d6 Oracle Bookmark by Gwyllgi,  this one attempts to bring the same kind of probabilities (or something as close as possible) using a single d20.

This oracle has been modified in a few way that make it distinct, beyond the use of a d20.

• In the original "yes and", "yes but", "no and", "no but", "add if" and "add unless" all have the same chances to drop (8,33%) on a single roll. Now "add if" and "add unless" have a 5% chance, and the others a 10%. chance. Similar changes affect "events" and "terrain" tables.
• It misses the open-ended oracle, and I do not intend to add one.
• The reactions are different, inspired by the reactions from Vaults of Vaarn by Graculus Droog. It assumes there is a  socialcharacteristic/skill in your games.
• The weather table has been done from scratch to be more climate agnostic. It basically means you have to  determine what is considered as "normal weather" in the climatic/seasonal context of the play but it's no big deal.
• I added some roll regularity suggestions.

It's really a barebone work, so if you have any feedback, I'd like to hear about it. Similarly, rate it weither you like it or not !
