Enchanted Armament is brilliant, my Balance is currently using a first gen one at the end of Avalon, the Sharpen Blades help you stack Balanceblades to deal extra damage. With that pet and a blade amulet, I can stack a 25%, 30%, and 35% blade on the same attack. The only problem is acquiring it, it's either available only from Gladiator Dimachaerus or from him and Tartarus, but it's still extremely difficult to get a first gen. My level 90 Life friend helped me fight the Gladiator when I was ~level 40, and I was lucky enough to get a pet drop. I'd recommend trying to hatch with someone rather than finding a first gen.
Of course, there's a lot of people who breed pets for perfect talent pools, like double damage, double defence, MC heal, and a blade IC. But if you don't want to go through the hassle of breeding for perfect talents, then Enchanted Armament is my favourite.
