Ian's fundamental inheritance was the prestigious True Form, the "Unyielding Fortress," which directly reached the Fifth Energy Level.
This was an inheritance geared towards protective knights, with a tough body, powerful defense, and almost inexhaustible stamina. It had impressive combat power early on and was very comprehensive.
In the later stages, it could even shake the earth and mountains, a single sword strike could carve out cliffs and ravines, aptly named the Sword of Cliff.
But if Ian were to evaluate it himself... the Unyielding Fortress was indeed strong, but...
It was slightly cumbersome.
To put it in another way, it was some sort of land god-beast that couldn't fly!
Would you say it's strong? Extremely strong!
But just like this god-beast, the Unyielding Fortress inheritance...
— could not fly.
Ian was well aware of why the Unyielding Fortress had such superior advantages and such major flaws.
After all, his teacher, Hiliard, was a 'Royal Guardian Knight.'
