What is better than getting sneak attack against another creature? Not much!
But if you aren’t a Rogue, then what good is dreaming of sneak attacks? Good question!
If a character is hidden, and their opponent cannot see them, they can have a sneak attack – but without the extra damage (shucks, no sneak attack damage here).
Instead when you leap out and attack the opponent, you get Advantage on the attack roll, AND a surprise round against them. So basically you get two tries to hit them (Advantage) plus you get to hit them twice ( surprise round, and first initiative round).
See? Sneak Attacks are more than just for Rogues.
