How To Beat Fionn Mac Cumhaill in Shin Megami Tensei 5 Vengenace

Shin Megami Tensei 5: Vengeance includes famous characters from the original SMTV. Later in the game, you will be joined by Fionn Mac Cumhaill, very powerful in his own right. Admittedly, you'll have to defeat him first. This won't be easy, but using these strategies should put you in a good position to win against him and recruit him into your party.

Before The Fight

Shin Megami Tensei 5 Vengenace: Beat Fionn Mac Cumhaill

One will always have to be very well-prepared against someone of this great strength. One must make sure to carefully consider both the equipment and strategy before combat in order to have the best chance of winning. Proper equipment and strategic adjustments really go a long way. So let's get into the meat of what's needed to overcome this challenge.

The Best Demons to Take With You

It's going to be very useful big-hand if some demon allies could be gotten out of one's way in the upcoming fight against Fionn Mac Cumhaill.

Cironnup is a strong contender for the position of fox spirit from Ainu folklore. Since Fionn focuses on Fire and Ice elemental attacks, its natural resistance to such will come in handy. She'll be very effective with an equip electric skill. On top of dealing damage, Cironnup can also support allies and hinder Fionn with a good skillset.

Lilim is a powerful demon recruit via a particular storyline choice. For such an abnormally high level character, she has actually very respectable electric skills as well. Sure, she's weak to ice, but most of Fionn's ice attacks are not actually that strong.

Ame-no-Uzume brings a perfectly rounded set of skills as the Japanese god of entertainment. Her electric skills exploit Fionn's weakness, and her healing magic makes her a supporter of incredible value.

This battle is just tailor-made for the Poltergeist, a playful spirit. It has immunities to both Fire and Ice and even packs a wallop with its electric attacks, so it will come in quite handy here. Its innate ability is Thunderous Melody, raising the party's electric damage output.

The final available participant in this battle is the companion character, Yoko Hiromine. As she resists Fire and Ice, and also has an electric attack called Zionga, she will be of great help in this battle.

Best Affinities for the Nahobino

The Nahobino is first an enemy weak to Force and Dark but can be changed further with the use of a miracle called Divine Amalgamation, where players could change their affinities based on demon essences.

First, resist Fire because it will be the most dangerous during the battle with Fionn Mac Cumhaill, in which he uses mostly fire-based attacks. He uses Ice as well, though this is not that bad, and having ice resistance is really not a priority.

Unfortunately, it is not easy to find a demon essence with both Fire and Ice resistance since these two resistances would seem to negate each other. The search will, therefore, be for Fire resistance. There are two obvious demon essences that can be had in the area: Jack-o'-Lantern and Hua Pao. Both have the upside of Fire resistance but the downside of having an Ice weakness.

Best Items to Keep On Hand

Gear up with the following equipment before engaging Fionn Mac Cumhaill to increase your chances of winning:

A Physical Dampener is a must to reduce the damage caused by Fionn's physical attacks, most importantly, his dreaded Mac an Luin +5. This will grant temporary invincibility from physical damage to the entire party.

A Fire Dampener is equally important, as Fionn's fire-based attacks can be devastating to the whole party. Use this item proactively to nullify incoming fire attacks for one turn.

An Electric Gem is also useful if available. This item inflicts a strong electric attack on Fionn and could result in large amounts of damage.

How To Defeat Fionn mac Cumhaill

With a full Magatsuhi bar, engage in battle so that it activates Omagatoki Critical and provide the most giant of advantages. Prepare to counter Fionn generating Magatsuhi with a Fire Dampener since he very often follows up this devastating attack with Maragion +4.

Equally important would be the utilization of defensive strategies. It is very critical to use Supportive Skills like Marakukaka to further beef up the party's defense since Dampener alone might not be enough to rely on. In addition, Matarunda should work on disrupting the ability of Fionn to attack and reduce his damage output.

Plan out Fionn's moves and adjust accordingly. Use a Physical Dampener after his Tarukaja in anticipation of his next Mac an Luin +5. By continuously adjusting to these tactics of Fionn and properly utilizing party skills, you whittle him down bit by bit until the end.
