In chapter 398 we can see how Robin has enough energy to stand straight, walk
around, tell a long story and shout across the ravine, despite being
handcuffed with Seastone handcuffs.

While in chapter 730 we can see how Luffy becomes completely immobilized after
touching the bars of the Colosseum.

Where does Robin get all this energy from? How come her energy isn't
completely drained as it was with Luffy's?

question
one-piece
How was Robin able to stand despite being cuffed with Seastone?


Many Devil Fruits give powers that have to be activated consciously,  
ie. they can be "switched on and off" completely. Luffy is a different case,  
his body is rubber all the times. He can´t make his body temporarily normal
again,  
he's deformable while sleeping, etc.

Seastone doesn't affect energy, health and so on, it affects _only_ Devil
Fruit powers.

As long as Robin doesn't try to use them, nothing would change because of the
Seastone handcuffs (well, except for being handcuffs).  
Luffy can't get rid of his rubber state, so...

Read that chapter (169) more carefully then...

![Luffy in Crocodile's cage](https://i.stack.imgur.com/xytha.jpg)

Here, Luffy _stands_ in Crocodile's Kairoseki cage.

![Still in the cage](https://i.stack.imgur.com/2XqdS.jpg)

Then he states that he has no power. Well, of course, since the cage is made
of Seastone.

![Smoker kicking Luffy's ass](https://i.stack.imgur.com/qrbfz.jpg)

Then Smoker kicks his ass and nails him down. And I think regardless of
Seastone any of us would have problems standing if Smoker _pushed_ his weapon
to our chest.

So to answer the question: Robin was in a weak state because of the Seastone
handcuffs back then, but she could stand because nobody pushed her down.
