Romann gains a juicy 5-10 Speed from his unique equipment, allowing him to serve as a PvP opener at max value. This upgrade pushes him at max up to the 115 Speed tier, tied with Dizzy, Vivian, and Judge Kise, and 1 point above SC Roozid. He’s still technically slower than them, however, due to how the Speed set interacts with base Speed. However, this still opens many doors for him, especially in PvP.

Skill Enhancement #1 - Gravity Arrow Upgrade

Gravity Arrow has a 75% chance to dispel 1 buff. Pretty nifty, and it provides some dispel power after his big S3. Probably not the best option, though.

Skill Enhancement #2 - Gravitation Upgrade Option 1

Romann gains a shield for 2 turns after using Gravitation. Ostensibly, this will protect him from counterattacks. This shield scales with his maxHP, however… which is one of the lowest in the game, at 142nd place. The shield strength is therefore pretty questionable. While it will probably shield him from at least some of Seaside Bellona’s counterattacks, Charles is still likely to blow through him like a hot knife through butter. But hey, I’ll take it.

Also, it’s on his S2, which you won’t use until your second turn. If he eats a counterattack before then, he’s also probably dead. Still a better option than...

Skill Enhancement #3 - Gravitation Upgrade Option 2

Gravitation gains a 50% chance to dispel 1 buff from all enemies. Unreliable, and rather redundant. Romann already strips all buffs from enemies with his S3, making this of questionable worth. In addition, heads-or-tails isn’t usually something worth investing in, especially not when you can get a guaranteed shield out of it instead.

Final Word:

Take Gravitation Upgrade Option 1, as Romann’s horrendous survivability needs improvement.

The Speed gain from the EE itself is fantastic, however, no matter which bonus ability is tied to it. It allows Romann to snag first turn and then S3. If you have the very rare artifact, Necro & Undine, Romann can technically give himself 100% CR as well and get an insane S3 -> S2 combo off. On Immunity set opponents, the combo will dispel all buffs, inflict 2 stacks of poison, and have a ~93% chance to decrease CR by 20%, or a ~69% chance to decrease enemy CR by 40% or more (before base EFFR is tallied). In addition, the damage dealt is decent, though not fantastic. On Immunity set opponents, Romann will deal ~1.7x AoE damage.

Romann as a whole gets a pretty significant upgrade.
