A True Pinnacle Boss Experience

Hello,
With all due respect,

I think that all the bosses in the game right now still lack the impact and sense of greatness that truly deserve to be called Pinnacle Bosses.
The unique items and jewels dropped by Pinnacle Bosses don’t feel special or rewarding emotionally when obtained.

Furthermore, Pinnacle Bosses are too easily accessible — such as Arbiter of Ash, Xesht, and others.

When I manage to defeat a boss like Arbiter of Ash, it feels as if there should be something more happening — perhaps something to trigger, or something strange appearing afterwards.
Or with Xesht, when the giant hand comes down and strikes Xesht as he dies — it feels like there’s something hidden behind that moment.

That’s why I would like to propose an additional concept or side content idea for a future league — or maybe just a concept I want to share.

I want there to be a true Pinnacle Boss, not one that can be defeated simply by holding Spark and standing still.
Not one that can be beaten by just using a single skill to win.

Instead, this kind of boss could have a small chance to appear after defeating a Pinnacle Boss.
For example, in the case of Xesht — normally, a giant hand comes down to crush him when he dies.
But imagine instead of that being the end, the hand changes its action — and the true boss appears for players to face next.

I don’t want such a boss to drop powerful loot or high-value items.
What I truly want is the thrill and joy of fighting — to have a battle that makes players genuinely think to themselves:

“This… this is a Pinnacle Boss.”
