Overview

Let’s get it out of the way; Fionn is a terrible Servant. His skillset does not synergize with his stats and their effects individually are just as lackluster, his generation stats are terrible, his hit counts are extremely low, his Noble Phantasm does poor damage, gives a completely unnecessary self-buff and has a mediocre overcharge effect.

Fionn does occupy a rare niche which is Art Lancer, a role that even now in Japan there aren't many options aside from him and Li Shuwen. If you want to make him works, put him into an Art-focused team that focus on maximizing his ability to spam Mac an Luin, as for an AoE Noble Phantasm, 4 hits per target can generate decent NP refund (though not by much). Another approach is to go with the Art Critical Damage Dealer route by supplying him with Critical Stars, however Li Shuwen will do this much better thanks to his natural Critical Stars Absorbtion and Critical Damage buff.

Overall, there is no particular reason to ever consider Fionn in your team when Servants like Cu Chulainn can do the Lancer job much better with less investment, and most if not all of his gold Lancer peers vastly outclass him as well.

Strengths

  • Trouble with Women at max level is a reliable taunt + dodge combo
  • Clairvoyance after his Rank Up quest is a good party-wide buff

Weaknesses

  • Terrible generation stats, combined with poor hit counts make him extremely frustrating in both generating critical stars and his NP bar
  • Poor damage output in general due to lack of strong steroids, Buster cards and an AoE Noble Phantasm with lackluster effects
  • Trouble with Women has an obscenely high cooldown

Craft Essence Recommendation

  • Formalcraft / Projection: For general purposes, Fionn will want Art performance buffs as it helps a lot with his NP generation and damage output 
  • Kaleidoscope / Imaginary Element / Halloween Princess: If you want to use him as a farming Lancer due to his AoE Noble Phantasm
  • Another Ending: If you plan to use Fionn as a critical damage dealer, then Another Ending might be the only thing that can make it work by providing him both Art performance boost and critical damage boost.

Level Up Skill Recommendation

If you happen to be one of the three players that actually bother using Fionn, then always max Magecraft first as it does help a lot with his Noble Phantasm and the NP refund from it.

Trouble with Women becomes reliable at level 10 due to the 100% rate on his Evasion buff.While it is still a terrible skill due to its extraordinary high cooldown it is still much better than his Clairvoyance prior to his Rank Up quest.

Post-Rank Up, there is an argument for maxing Clairvoyance (Beauty) before Trouble with Women if you value the party wide NP generation buff and star generation. Overall, Clairvoyance (Beauty) is a better long-term investment than Beauty of Trouble with Women.
