Stuck at final boss....

The shadow queen is pretty difficult. If I could say, it took me 5 tries to win. I would recommend you be level 30 or higher with a minimum of 40 HP, 25 FP, and at least 18 BP. Don't worry, the palace of shadow isn't a point of no return, but I would recommend grinding there and for amazy dayzees in creepy steeple path. If u havent gotten to floor 50 on the pit of 100 trials, you should. You don't have to get to level 100. I would recommendgetting to 50 and leaving. You can then carry 20 items. See if u can get 4 ultra shroom, 4 jammin jellies,1 jelly ultra ( made by mixing ulra shroom+jelly.) % life shrooms, 3super shroom, 2 zess teas, and 5 maple supers (made like jelly ultras except with super shrooms and maple syrups, and have goombella, vivian, and bobbery at ultra rank. Use goombella mainly and have her use rally wink. Whe the boss charges switch to vivian and have use veil to prevent 13 damage. If goombella dies and u want a new strategy swich to bobbery and get good at damage counters. Also badgewise I recommend finding and equippind power bounce, peekaboo (if u dont wanna tattle) charge and charge P, FP saver for mario, Defense plus and for partner. Now go in and see those credits!

I took her on in level 27, I had a page full of life shrooms. I also had 6 Whacka Bumps, 1 Jammin' Jelly or two, and an Ultra Shroom. In her second phase I had Bobbery out, I used Art Attack in the first two turns, and power smash on the third one. I had Bobbery used Bob-ombast on those three turns, I had a slot machine that healed all my stats. (It should always work) I then kept on doing the above with Vivian using Veil when a powerful attack was used. (When she raises her attack by seven).

The items and moves helped me.
