Sui Xiong was not a mad scientist in the usual sense, but that did not mean his methods were particularly gentle when conducting research—especially research on living bodies.
Quite the opposite. Since he could ensure that the goblin chieftain being studied would absolutely not die, his research methods... if they were filmed and uploaded to Earth's internet, they would definitely attract a huge crowd of enraged animal rights activists—assuming goblins counted as animals.
The results of that research were outstanding. In barely more than ten days, he had thoroughly figured out the goblin chieftain's bloodline and abilities, and finally created the spell he wanted.
It was just that it differed slightly from what he had imagined beforehand.
He called the effect of this spell "Giantification." It was not a spellcasting ability, but a bloodline ability. In other words, using it required not powerful magic, but a strong physique.
By Sui Xiong's estimate, one needed a physique close to what ordinary people called an "iron man" to withstand the strain of this ability. That more or less meant one had to be a near-high-level melee profession, or a high-level ranger-type profession, to possess such a body.
As for mages... forget it. Even legendary mages could not possibly have such powerful physiques. Only sorcerers might manage it.
Oh, mages were possible too. For example, combat mages like Magic Cannoneers, who placed extreme emphasis on physical training and possessed physiques no weaker than rangers of the same level, could indeed meet this ability's requirements.
But no matter what, this ability leaned far too heavily toward physical fitness and was not suitable for use as a spell. After giving it some thought, Sui Xiong ultimately decided to make it an ability for paladins and grant it to his clergy.
As for its name, Divine
