Ribbits AA crit buff actually lasts 3 seconds and not 2.

Scorch does have the highest crit happiness bonus though at 12, and a few at 10% like Horton.

Another + about Gyrm is that with that extra second of crit buff, you'll be able to cycle through 2 full rotations of aim/sp/nox.

Shadowlurk is another top tier crit pet and also has the damage boost, dont overlook this underrated pet!
