Without a doubt.
Inanna was Iver's final Great Sin Beast—the strongest Great Sin Beast, and also Iver's strongest Phantom Demon Card... by far.
Not only did her summoned true body possess overwhelmingly superior attributes, but her entrance effect alone provided unconditional, instant, permanent area-of-effect control, along with a substantial permanent reduction to defense and resistance... This control effect could even resist dispelling; it had to be dispelled twice in succession to remove it.
How could this be anything other than a skill belonging to an extremely high-difficulty BOSS?
Even in the highest-difficulty dungeons, it would be an ultra-dangerous mechanic that could barely be resisted with special skills—something players could not simply endure. If handled incorrectly and several people were caught by it, the entire party would be wiped out. Its difficulty was enough to make restarting seem preferable.
Moreover, even if Iver did not summon Inanna's true body, the upright effect of this card alone was already powerful enough--
It was equivalent to a large-area, long-duration group preservation spell that could be used once for only five points of mana. Its other effect was actually the key: everything illuminated by its radiance was regarded as "touched."
--This meant that as long as the line of sight was clear and the light could reach the target, Iver could use powerful Phantom Demon Cards such as Star Ice and Bewitching Aura from a considerable distance, despite their requirement for close contact... or directly summon a Paradox Flame Butterfly or Wild Hunt King behind an enemy!

Iver held the card with immense satisfaction, turning it over and over in his hands, unable to part with it.
Inanna's true body was level 59--the highest-level existence Iver had seen to date.
This was the highest
