Brief question regarding haste

[Alabenson]

When a dual-wielding character is affected by the haste spell or a similar effect, does that character gain an extra attack with both weapons, or only with their main-hand weapon? The RAW is a bit vague on this point, and it has come up several times in my campaign.

[Greenish]

Only on one weapon.

[Cog]

...or only with their main-hand weapon?
Greenish is correct, though to be more specific, it's a single extra attack with any weapon, not necessarily the main-hand one.

Ah, that's how the DM had been ruling it. Thank you.
