===Increasing likelihood of critical hits=== | |||
Any effect that triggers a re-roll of an attack die will increase the likelihood of landing a critical hit. Attacking with [[Advantage]] almost doubles the likelihood of rolling a critical.<ref>https://statmodeling.stat.columbia.edu/2014/07/12/dnd-5e-advantage-disadvantage-probability/</ref> Features that allow for situational rerolls, like {{Sai|Halfling Luck}}, similarly increase the odds. Reducing the critical threshold increases the odds accordingly; taking into account advantage and multiple attacks, the odds of scoring a critical with a character in one round of combat are as follows:<ref>[[Guide:Book's Guide to Crits]]</ref> | |||

==Reducing critical threshold== | ===Additional effects on critical hit=== | ||
On the other side of things, some effects add add additional value to critical hits when they occur. These include: | |||
*{{SAI|Brutal Critical}} and {{SAI|Savage Attacks}} add an extra damage die to the damage of the attack, i.e. an attack dealing {{DamageText|1d10|Bludgeoning}} will critically deal {{DamageText|2d10 + 1d10|Bludgeoning}}. Additional damage dice, like those from battle manoeuvres, are not subject to this additive bonus, with the exception of {{SAI|Divine Smite}}. | |||
*Effects that reroll damage rolls will see greater benefit on critical hits, since the raw number of damage rolls increases: | |||
**{{SAI|Savage Attacker}} rerolls all damage die twice. | |||
**{{SAI|Great Weapon Fighting}} rerolls damage die for two-handed melee weapons, when rolling a 1 or 2. | |||
**{{SAI|Organ Rearranger}} rerolls damage die on critical hits, when rolling a 2. | |||
*Effects that provide a unique bonus when a critical hit occurs: | |||
**{{RarityItem|Spellthief}} restores a level 1 spell slot on critical hit. | |||
**{{SAI|Paralysing Critical}} paralyzes a target on critical hit, once per long rest. | |||
**{{SAI|Mortal Reminder}} possibly frightens enemies on critical hit. | |||
**{{RarityItem|Dolor Amarus}}, {{RarityItem|Vicious Battleaxe}}, and {{RarityItem|Vicious Shortbow}} add a flat damage boost to critical hits. | |||
**{{RarityItem|Sword of Life Stealing}} adds a flat damage boost to critical hits and adds [[Temporary Hit Points|temporary hit points]]. | |||
**{{SAI|Great Weapon Master: Bonus Attack}} enables an attack using a bonus action, after a critical hit. | |||
**{{RarityItem|Intransigent Warhammer}} knocks creatures prone in a radius on critical hit. | |||
== Reducing critical threshold== | |||
Some feats, passive features, and items reduce the critical hit threshold by 1, allowing the creature to land critical hits by rolling either 19 or 20 on attack rolls. Multiple sources of this effect stack, allowing the critical hit threshold to go even lower than 19. | Some feats, passive features, and items reduce the critical hit threshold by 1, allowing the creature to land critical hits by rolling either 19 or 20 on attack rolls.
