This is how you beat them on the gold level. Unless you have like over 1000 stamina points, you can do one per day. Save up all your stamina until you will be able to level after doing some jobs, then use all your stamina to start the attack. Do jobs to level up. Use all of your stamina again after you level up. Do jobs and use an energy pack to level up again. After you level up again, use whatever stamina you need to finish the Boss. Repeat 24 hours later.

Doing this gives you basically 3 full amounts of stamina to beat the boss. If you don't have enough stamina to beat the boss after 3 runs of stamina, then your character isn't well-rounded enough.
