[QUOTE="gelf, post: 8385225, member: 96468"] The unexpected attack is a common trope in D&D: Ambushes set by goblins to rob travelling merchants; Assassins sneaking into bedchambers to kill a sleeping mark; Treasure chest mimics, waiting to eat the curious and greedy; A doppelganger disguised as an old friend to attack when their target is most vulnerable.

It's important to recognise that attacking a surprised creature isn't a source of the advantage. But a creature is often surprised by hidden creatures, and being hidden is a source of advantage on attacks. Once a fight begins, you can’t be surprised again in the same encounter. If another hidden creature enters a combat encounter on a later turn, no one is surprised, although the creature still benefits from being unseen, granting advantage to its attacks.

[B][SIZE=6]What abilities interact with surprise?[/SIZE][/B] There are abilities which specifically interact with surprise. This isn’t a comprehensive list, but here are some notable examples. [SIZE=5][B]Monster abilities:[/B][/SIZE] [LIST] [*]As mentioned in the example above, [B]bugbear[/B]s have a trait which deals extra damage to surprised creatures.

They are a frequent source of surprise. [*]The [B]gelatinous cube[/B] has the [B][I]Transparent[/I][/B] trait which specifies that a creature that enters the cube’s space while unaware of the cube is surprised. [/LIST] [B][SIZE=5]Player abilities:[/SIZE][/B] [LIST] [*]Most notably the rogue subclass [B]Assassin[/B] has the 3rd level feature [B][I]Assassinate[/I][/B] which grants advantage against creatures that haven’t had a turn in combat and turns any hit into a critical hit against surprised creatures. Questions about surprise in 5e are almost always prompted by the assassin rogue. [*]A character with the feat [B]Alert[/B] can’t be surprised as long as they’re conscious. [*]Although it’s not a specific interaction, the ranger subclass [B]Gloom Stalker[/B] 3rd level feature [B][I]Dread Ambusher[/I][/B] ([I]Xanathar’s Guide to Everything[/I]) only functions on the first round of combat, so being surprised is particularly bad for gloom stalker rangers, simply by denying them one of their most powerful features.
