How to beat Baron Brixius with all three classes:

First class:Biological

This is the easiest class to beat him with.

Get 2/2 in Disrupt and 2/4(at least,more if you want) in Integrity.

Put all 4 Disrupts on your ability bar.Use it every turn.The Baron will use Deep Burning the first time,then Electrical Storm,then Deep Burning,Electrical Storm,etc...

The Electrical Storm does not do nearly enough damage to be a threat,especially with Veradux healing.Battle:won.

Second class:Psychological

Psychologicals also have a easy time with the Baron.

All you need is 2/3 in Shock Coma,1/4 in High Voltage(and 1/4 in Shock Therapy because you need it to get High Voltage),2/2 in Retrogade,1/1 in Overdrive,3 extra ability points for the required skills to get Retrogade,and put the other points in whatever you want.Make sure that you also have more HP then Veradux and/or Roald.

The battle will be easy.

Use skills in following order:
High Voltage
High Voltage
High Voltage
Shock Coma
Shock Coma
Retrogade.

This damages the Baron for 120% of his HP(OHKO).

Third class:Hydraulic

Hydraulics have the longest battle,but still easy.

Use the Flash Freeze - Regulate - Flash Freeze - Regulate - Mind Freeze - Regulate untill Flash Freeze is Avalible Again - Flash Freeze - repeat.

This will keep the Baron from using Tick Tock.He will regain his focus during the Mind Freeze part,though.This focus gain is nothing compared to the regulates,thankfully.

If the Baron's Electrical Storm does high damage to you,though,just put Veradux on Phalanx mode and everything should be fine.Hope this helps!

I hate this guy and he's super annoying. Lemme just tell you something.

This guy is not about dealing damage. You need to heal, protect, and most of all TAKE AWAY HIS FOCUS. I'ts also needed to have a stun spell ready and use it a lot. Those are my tips on how to beat him. All armor that has high strength and vitality, you should equip to Roald and Veradux. Dux need instinct for healing, so equip the highest instinct and vitality armor onto him. Keep both on Phalanx and disrupt his focus as much as possible.

Those are my tips.

Both my teammates died when he was still at 40000 HP. Then he kind of commited suicide.

High Voltage
High Voltage
High Voltage
Shock Coma
Shock Coma
Retrogade.

You can't use High Voltage 3 times in a row, the combo is High Voltage
High Voltage
Shock Coma
Shock Coma
High Voltage
Retrogade.
, but then you need 3/3 Shock Coma, so the Shock Coma lasts long enough to heal when you use Retrograde.

concentrate on healing and removing his focus in any turns where everyone has moderate to good health

I could not get a frosted fate but I have 5 rune blades!!! Could I beat the heck out him with it!?!

Use level 2 Disrupt to drain his focus, then he'll use the holy scars (skill that makes him much more vulnerable). Keep doing this and you'll win :D

To survive the Baron's Tick-Tock attack, make sure Veradux keeps on healing you. Just a tip. :)
