2 seconds is just over 1 1/2 auto's with Heroic Gloves (1.2-1.6k), or just over 2 auto's with a Haste Elixer (1.6-2.2k). Taking into account that a lure is permanently up, as is a smoke bomb, he will add 90 damage per auto for 60 seconds, which, with heroic gloves would be 4,050 Damage Added (with 1.2-1.6k lost), or 5,684 damage added on a haste Elixer (with 1.6-2.2k lost).
All in all resulting in (with lures and smoke bomb up):
2450-2850 damage gained with Heroic Gloves
And
3484-4084 damage gained with a Haste Elixer
