It does restrict your own movements but makes the selected target completely unable to act. So this skill can work alone but also has a wider range of usefulness in parties.
I find being blocked out of everything except Normal Attack (which is underwhelming) and Ultimates far too limiting to be of use in a single party. The other mobs can still act freely. Even in a party, this might be only worth against a boss. The primary issue is, that killing enemies is the best approach to end battles and losing Nana is more punishing than benefiting the party. Maybe still allow normal skills? Or limit target only to the one you are constricting instead?
BTW, would Restriction help against Shira's test? That would make the fight quite easy there.
Yes there are two transformation currently for which i have found no good/useful ability to give, lamia is one of them. Any ideas are welcome!
Some kind of tremorsense? Like showing up the way to secrets? Might be tough to implement. Or maybe instead seeing dark, you can see everything in monochrome and brighter instead automatically.
I just noticed, Lamia has "Tail Strike", too. "Tail Attack" for Melia?
Lamia's Plaything seems underpowered.
Lamias inherited skills had no costs associated.
As an observation, I barely play as human, but when I do, I basically now only buy support skills (or leeching attacks) from the inherited forms, since I have lots of attack skills anyway and I can't use those I have before the fight ends. Maybe longer boss fights, but most are forced into a certain form, so the point is moot.
