"Instrument of Faith"

You will receive this achievement upon completing Chapter 11. For those of you having troubles with the Boss (Barthandelus) at the end, I have written a base guide for you to follow that should help you defeat him.

Boss: Barthandelus
Approx. HP: 3.3 Million
Total Time to Defeat: 11:23
Doom: Nope... he did not have a chance to use Doom on me =)

Characters Levels/HP/Weapons

Lightning
COM: Level 4 (Maxed)
RAV: Level 4 - Helter Skelter Level 48
MED: Level 3 - 3543 HP

Hope
SYN: Level 3
MED: Level 4 (Maxed) - Airwing Level 26
RAV: Level 4 (Maxed) - 3360 (with HP boosting Accessories)

COM: Level 4 (Maxed) - Glaive Level 35

Paradigms:
Lightning/Hope/Fang
COM/SYN/SAB (Starting Paradigm)
MED/MED/SEN (Used when low HP to quickly Heal and get rid of Debuffs)
RAV/MED/COM (Used to build up stagger, while heal if needed)
RAV/RAV/COM (Used for quickly building Stagger when HP is high, and also to hit him hard when Staggered)

From looking at the Paradigms I used to defeat this boss, it is pretty straight-forward on what to use and when to use it. Now the rest is up to you to use them properly and to get the right timing. A good thing to keep in mind, this boss is really weak when debuffed, so don't be shy with using Fang as a SAB and Hope as a SYN to buff your party up. I also don't remember the exact name of the attack, but he will use a laser attack that does your party for some damage. So when he is going to use that, remember to quickly switch to your "Combat Clinic" Paradigm so help reduce some damage and heal quickly. I also don't recommend using your Summon until you are in a rough-spot or until near the end to quickly finish him off.

This is mainly just for a base-guide, so people can have a straight forward guide to help them get started. You do not have to use this exact method, but this is what I did and it worked perfectly. Just remember to do some Trial & Error, and you will get passed this guy, he isn't that hard and you will realize it when you pummel him =).

Hope this helped!

Good luck!
