DPS Meter

The DPS Meter is an informational accessory that displays the DPS of the weapon that last dealt damage to any entity, including NPCs, Target Dummies, critters, and other players. The DPS Meter can be purchased from the Traveling Merchant for 5 GC.

The DPS Meter is one of the three parts necessary to make the Goblin Tech, with the others being the Metal Detector and the Stopwatch, and as such is a required ingredient in crafting the Shellphone.

Unlike most accessories, informational accessories such as the DPS Meter do not need to be equipped in an accessory slot. The DPS Meter may be carried in the player's inventory without loss of functionality, unless equipped to a social slot. Additionally, the info it provides will be shared with players of the same team in multiplayer that are within 50 tiles. Keep in mind modifiers will no longer apply to the player when not equipped.
The DPS Meter takes into account every factor by which actual damage is affected as well, such as critical strike chance, enemy defense, or boosts from armor, accessories, buffs, etc.
Strangely, the DPS Meter is unable to account for critical strikes dealt by melee weapons that swing overhead, though critical hits dealt by any projectiles that they fire are recorded properly.
The DPS Meter displays the damage per real-time second instead of the damage per in-game second (60 ticks). This is apparent when the frame rate is less than 60 and when Frame Skip is enabled.
