(This applies for every boss from Lynx to Shogun)

Grind in Survival mode until you can fully upgrade all of your current equipment (you can play tournament fights and challenges while doing so but make sure you save the last tournament fight and challenge later). After upgrading all of your current equipment, play the last tournament fight and challenge and finish the boss. No need to enchant (save your orbs for later)
