What's important is that someone dared to tamper with his cake, which is absolutely unforgivable.
The same tentacle arm, wielded personally by Dimogorgen and in the hands of Great Kodi Koli, is incomparable.
After all, the latter is only borrowing the other's strength, and even though the tentacle arm is grown on his body, it's regarded as a first-contact otherworldly weapon. To be able to wield it is already commendable.
As for Dimogorgen, he has immersed himself in its use for tens, or even hundreds of thousands of years, honing its techniques to an unparalleled level.
Even the Legendary Six-armed Snake Demon who specializes in close combat is no match for him.
Just one tentacle arm was enough to put the Six-armed Snake Demon Nightshadow in a miserable situation; her usually unpredictable Short-Distance Teleportation became completely unreliable.
The tentacle arm could precisely predict Nightshadow's teleportation exit, waiting there for her at every Attack.
