Dragon Quest VI: Realms of Revelation/Arkbolt

Path to Arkbolt
The path to Arkbolt is very straightforward; just warp to Port Haven, then sail a bit to the upper-right. You shouldn't even encounter that many monsters along the way. Once you're there, make sure you have a Amos, Carver, Milly, and Nevan party.



Arkbolt


There are yet more doors that you cannot unlock yet, but that's fine; you can still get the 12-13th Mini Medals as well as some new equipment here. You'll want to buy the Battle Axe for Carver, one Silver Cuirass for Milly, and two Magic Shields for Nevan and Amos. Also keep that in mind that Yggdrasil Leaf amounts will no longer be given, as they will vary depending on the player.

Rest up at the Inn, talk to the guard blocking the entrance to the 2nd Floor, and you will fight a mini-boss!

VS. Bronson
This one is a fairly easy battle; Flame Slash is essentially just a physical attack that can do 1.3x regular damage to anyone who's not resistant. On the other hand, those who have strong resistance or immunity to Frizz will only take 75% and 30% Damage respectively. In other words, the elemental slashes are useful only to monsters, not to you.

In any case, Bronson has nothing but physical attacks to throw at you, so Buff and Kabuff utterly trivialize the fight. If you do not have those for whatever reason, you can simply heal everything off with the Ghent Staff. Once you defeat him, heal up at Madame Luca's (or just use the Inn if you don't mind paying money), get the 12th Mini Medal on the next floor, and hurry to the next battle.

VS. Brick & Brock
This fight is mildly harder than Bronson, but still nowhere close to the level of Murdaw. If you haven't gotten Buff on anyone but Milly, you may wish to remove Rex's vocation, and have him fight instead of Nevan If you decide to do that, do the same for Milly, and be sure to give Rex the Fire Claw to use while he's Sapping Brick and Bronson (Amos, for his part, does well with a Ghent Staff and Cautery Sword). If that's the route you decide to go, have Milly keep buffing people in order to stay ahead of Brick's Kasap.

None of this should be necessary, however, if you followed the walkthrough; you should be able to trivialize this fight just by spamming Kabuff and using Buff on Milly and Nevan. Once you do that, you can essentially just pound the two into submission with Focus Strength + Knuckle Sandwich and Frizzle. And use Boom every 3 turns; Brock will cover Brick, meaning that he'll take double the amount of Boom strikes he would've otherwise taken.

Whatever you decide to do, kill Brock first; he may not have Kasap, Oomph, or Double Up, but he attacks more often than Brick does. Talk to the king after you have swept those two aside, and then talk to Brutus. He'll leave for the room marked by I. Rest at Madame Luca's; once everyone is healed up, get the 13th Mini Medal and fight Brutus!

VS. Brutus
Brutus is one of the very few fights that are harder in the remakes than they are in the original SNES. Thin Air only did (Level*2 + 30)* +/-10% in the SNES, but was increased to (Level*2 + 50)* +/-10% in all of the remakes. Every monster in the game has an internal level, and Brutus's happens to be 5, hence the damage ranges listed in the Attack Patterns.

In any case, you will want to use caution when fighting against him. On the very 1st turn, Milly will want to use Buff on herself while Nevan Defends. Then when the 2nd Round comes around, have Milly use Buff on Nevan as he uses the Ghent Staff on her.

Carver and Amos will want to use Kabuff twice. After that, Amos and Carver should use Focus Strength + Double-Edged Slash, Milly should Midheal every time Brutus is about to use Thin Air or Multislice, and Buff on every other turn. As for Nevan, he should just keep spamming the Ghent Staff. You can occasionally use Frizzle with your mages if you wish to; but it will only do around ~30 Damage a pop with Brutus's resistances.

This is assuming that you have followed the guide to the letter up until now. If you do not have Buff on most of your characters, you will want to remove Rex's vocation, and have him fill in for Nevan; durability will be at a premium for parties who only have Milly to help with Buffing. If this is you, let Rex land Sap on Brutus twice to help out Amos and Carver. In addition, Amos will want the Ghent Staff since Rex and Milly will both be busy slinging their respective spells

Path to Wayfarer's Pass
When all is said and done, talk to the King, then talk to the minister in order to receive an empty casket. Then go to Wayfarer's Pass.
