Few servants can make use of both the Arts performance and Star generation buff, making this a difficult Mystic Code to use. The niche use case of the buff prevention further hinders its general effectiveness.

Skills Explanation:

  • Spiritron Boost grants one servant up to 50% Arts Performance buff for 1 turn. Since Arts performance buffs also increase NP generation/star generation buff for Arts cards, it works extremely well with Servants who can capitalize on these other bonuses.

  • Stepping Stone to Ultimate Victory increases one servant’s Critical Star generation by up to 100%. Although this is a very high amount, critical stars are usually inconsistent due to distribution and reliance on proper cards and hit-counts.

  • Punishment negates the 1st self-buff that an enemy uses. This can be particularly effective in fights where the boss has a powerful self-buff, like Marie Antoinette and her invulnerability. Punishment’s cooldown and singular instance of effect lowers its influence because some bosses can simply spam buffs.

Notable Strategies and Users:

In theory, this Mystic Code works best with an Art-focused multi-hit Servants to make use of its two first buffs. Notable examples include Orion or Vlad III, who have powerful multi-hit Noble Phantasms and skillsets that revolve around critical stars. Emiya is also a notable user, as he has 3 Art cards in his deck and a Noble Phantasm with high hit count.

In practice, you will most likely be using the first buff for extra damage, with the other two usually being afterthoughts or dead weight.

Levelling Value:

The high scaling buff values of the Arts and Star Generation buff and the required EXP to completely level up being marginally higher than the default Mystic Code are two benefits of this Mystic Code.  However, unless you have a reason to use it often, it may not be worth levelling up for the higher values alone due to the difficulty in making the most of all three skills.
