Advantage / Disadvantage

Effective immediately I'm going to start using Advantage and Disadvantage in the Magusien ruleset.  Unlike 5th edition I will not be using it in place of other rules, so nothing's really changing.  What I WILL start doing is using the terms to describe situational circumstance on rolls.  For those of you who need a refresher;

Advantage lets you roll 2 d20's and pick the higher of the two.

Disadvantage is when you roll 2 d20's and pick the lower of the two.

These can apply to others as well, of course, not just PCs.

You, Sir, have a fine taste for rules. Cheers!

Will we know when we roll at advantage or disadvantage?

No I'm going to keep it completely secret from you because I'm both vindictive and a horrible GM.

Cool, I've liked the advantage/disadvantage system so far so I am all for seeing it used in your system.
