Guide:Action Surge (achievement)

Action Surge is an achievement requiring the player to attack 5 times in one turn.

One way to get this achievement is by casting  haste on a level 5 or higher fighter, then using their  Action Surge ability. Because level 5 fighters get 2 attacks per action, they should be able to attack 6 times, therefore unlocking the achievement.

Alternatively, one can cast haste on an  enraged Berserker. They can attack 2 times per action, and can use  Frenzied Strike or  Enraged Throw to get their fifth attack.

This can also be accomplished without haste by multiclassing Rogue (Thief) 3 and any Monk 1, by attacking and then using  Flurry of Blows twice.
