Understanding his limits mark of a true genius!

Ronan had already understood the basics of elemental manipulation when he was inside the cave of penance.

He had always felt a faint connection to the attacks he produced as while he could not control them perfectly , he could always correct their angle by a few degrees after he released them.

However it was only after his encounter with Shakuni that he truly broke through his limits and learnt the first stage of elemental manipulation.

In that sense he was not a complete amateur like Percy while trying to learn the Armour of flame.

Covering himself in fire, Ronan tried to replicate the armour of flame as per his own understanding but when the fire barely covered his ankles it stopped rising as Ronan quickly understood the limits of his fire manipulation.
