Then we divide it by the number of possible outcomes (20^2 where 20 is the number of sides on the die). Then we square it to get the number of possible times that 2d20s will NOT yield the AC or target number. Normally the -7 would be -1 (because will always roll at least a 1), but we have a +6 modifier, so we need to decrease the AC or target number by that amount. The equation is 1 - ((N-7)^2) / 400, where N is the AC. The 5e advantage is far more difficult because with two dice it creates a curve.

This also increases the maximum possible and (as we see in +3 and +4) narrows the minimum you can roll.

It increases your chances by 5% times the modifier. Simply decrease the percent by 5 each time you go up an integer.Ĭalculating the Variant Advantage (+2) is similar. Each side on a d20 has a 5% chance of happening, so you will hit an AC of 10 85% of the time and miss 15% (3 x 5) of the time. Without any form of advantage and a +6 modifier to our roll, you need to roll at least a 4 to hit an AC, which excludes numbers 1-3 as successes. I made this assuming that most players will have a 16 in their best stat and assumed a proficiency bonus of +3, which is where much of the game takes place for players that don’t have long-running campaigns or don’t start at a higher level. Here’s a table comparing how often a player will hit a creature with a certain Armor Class. Let’s analyze how this would affect gameplay. I don’t want to post this as a catch-all variant and leave it at that, though. If a creature has advantage and disadvantage, add the bonus and penalty together to reach the total modifier to the roll. Disadvantage imposes a -2 penalty to their d20 roll, and an additional -1 for each additional instance of disadvantage. Each additional instance of advantage adds a +1 bonus to the d20 roll. Whenever a player gains advantage, the player instead gains a +2 bonus to their d20 roll. This variant plays more like 3rd edition, where stacking bonuses was not only encouraged, but imperative to success. We came up with an idea that promotes an increase in design space as well as rewarding strategy without tilting the game to the breaking point. When I talked to Mike Mearls after meeting him at Hascon, part of our discussion regarded this and its limitations to design space. Normally, Advantage and Disadvantage cancel each other out and don’t stack. DnD 5e homebrew short rest variant rule Dungeons and Dragons Once a player benefits from a Quick Rest, they must complete a short or long rest before they can do so again. For instance, a bard’s Song of Rest will grant its bonus hit points for players who spend HD during the Quick Rest. Instead of regaining ability uses, a player can choose to replenish one expended spell slot of up to 5th level.Ī Quick Rest, in most respects, counts as a short rest for certain effects.If the ability has multiple uses (such as Bardic Inspiration) or uses a pool of resources (such as Maneuver Dice or Ki Points), the player only regains ½ of the expended uses, rounded up. In addition, players with class features, racial traits, or other abilities that replenish expended uses after a short rest can replenish the use of one such ability of their choice.Players can regain hit points using hit dice, much like during a short rest, except that each player can only spend up to 1 Hit Die when taking a Quick Rest.A Quick Rest allows the following effects: A Quick Rest takes 5-10 minutes but is less useful than a short rest. Players can take a Quick Rest to catch their breath when there is no time for an hour-long short rest. Of course, you can always switch to one of the alternative rest systems with shorter rests (10 mins/1 hour) or longer rests (8 hours/1 wk), but this variant fits in somewhat neatly as a “partial” short rest in a pinch: the Quick Rest! Variant: Taking a Quick Rest Do you find your players tiring too easily mid-dungeon but don’t want them to take a short rest? Perhaps it would be too dangerous to rest but the players are lacking in too many resources, or maybe a short rest would prove too forgiving in the circumstance.
