Thomas Edison can be described as a support/utility Servant who focuses on critical star generation and enemy disruption via his Noble Phantasm which can seal enemy skills and NPs. He also has a gimmicky skill, Concept Improvement, which increases the overcharge level of an ally’s NP by two but overall, doesn’t have much impact. Rather, he is better used as a support for Crit teams as among other things, he can give out a stream of stars using Mass Production.
However, as Edison has low attack, poor star generation, and as Mass Production has an overtly long cooldown, he may not be the best choice as a support. His NP has some utility, but there are other defensive Servants better at protecting their team from an NP as opposed to merely stalling it for one turn. Overall, although Edison has tools for supporting Crit lineups, he’s outshined by other more dedicated supports. His third skill, though having its niche uses, can’t alone carry his lackluster kit.
Unique Skill and Overall Utility
Edison's main defining feature is the presence of Concept Improvement which can be used to increase an ally’s NP overcharge by two. He is the only Servant who has this ability in the game. His Noble Phantasm can also seal all enemy skills and NPs as well, allowing him to also stall his opponents’ NPs for one turn.
Decent Critical Star Support
Edison’s Concept Improvement, in addition to providing overcharge boost, also increases Critical Star drop rate. Coupled with his Mass Production, which can give a maximum of 10 Critical Stars per turn for 5 turns, and his relatively low Star Weight, he can also be used as a Crit team support.
Good NP Gain
Being a Caster and having three available Arts cards to possibly do Arts Brave chains helps Edison charge his NP gauge faster. Coupled with Mass Production which gives NP charge on a turn by turn basis, Edison can get and fire his NP quite quickly.
Unique Skill is Limited in Effectiveness
While Edison is the only Servant who even has the ability to give overcharge to a NP via Concept Improvement, most of the time it becomes a non-factor in battle. While some Servants do have nice overcharge effects, like Berserker Lancelot with his attack buff, the impact of said overcharge effect is more often than not negligible. More often than not, it’s more favorable using a different support Servant instead.
Edison has the second lowest ATK among all Gold Casters, only better than Medea Lily whose primary job is a support Healer. Although Edison is mostly relegated to a support/utility role, having poor attack doesn’t help all the same. Additionally, Edison doesn’t have high durability to offset his low damage, having only a low rank in Morph.
High Cooldown on his Bread and Butter Skill
Edison’s primary skill is his Mass Production which gives a good amount of NP charge and stars, but its main limitation is that it has an extremely high base cooldown of 12. Even though the effects last for 5 turns, even at level 10, there’s still a 5-turn gap where the skill is inactive.
- A Fragment of 2030: Allowing Edison to generate more stars is great when coupled with Mass Production’s star generation, and it also is useful during the times Edison doesn't have his second skill up.
- Little Halloween Devil / Divine Banquet / Prisma Cosmos: Edison’s Noble Phantasm as some utility in that it can seal enemy NPs and skills. As such, it would be beneficial having it up as soon and as much as possible, so he can use as many times as he can before the enemies can use theirs.
- Iron-Willed Training / Threefold Barrier: As Edison’s second skill is active over multiple turns, if he dies any time during the active duration of his skills, the remaining turns are wasted. To counteract this, he can be given craft essences which make him hardier in addition to Morph which already gives him some defense.
- Mass Production is Edison’s main bread and butter skill as a support/utility Servant. At a whopping 12-turn cooldown, the less time the skill is offline the better. The stars and NP gain also increase with the level which is essential to his role.
Concept Improvement should be levelled up next. While the overcharge increase doesn’t change, the lowered cooldown will allow him to use it more often. Additionally, the increase in Critical Star generation will help him support better in Crit team compositions.
Morph should have the least priority. Although having survivability is not bad, it doesn’t help Edison fulfill his niche that much as the other skills do.
