I'm Not the Goblin Slayer

[Fantasy World, Slow-Paced Adventure, Mage, Monster Bestiary Collection]

Arriving in a fantasy otherworld and obtaining an adventurer's handbook that collects slain monsters—the more you kill, the stronger it gets—Gauss originally thought he would embark on a classic adventure of defeating giant dragons, slaying demons, and saving the kingdom. Instead, he faces goblins proliferating endlessly like pests, impossible to fully exterminate, along with the rapidly growing kill counts and rewards on the monster bestiary, his expression growing increasingly helpless...

You have cumulatively slain 1000 goblins! Intelligence +1, Strength +1, Constitution +1.

Title "Goblin Slayer" upgraded to "Goblin Expert". You are a goblin expert; few people know more about killing goblins than you.

"..."

Title "Goblin Expert" upgraded to "Goblin Nemesis". You are the most ruthless butcher the goblin race has ever seen, an eternal shadow of terror engraved deep in goblin bloodlines.

Current effects:

Effect 1: Nemesis. In battles against goblin-race creatures, damage dealt is increased by an additional 50%.

Effect 2: Bloodthirsty. Killing goblins has a chance to randomly restore 10% stamina.

Effect 3: Deterrence. You possess absolute intimidation against goblins and related evolved races; enemies facing you will suffer a massive drop in status.

Looking at the titles continuously advancing on the panel,

Gauss really wants to know if there's any way to stop people from putting the title "Goblin Slayer" ahead of his renowned titles like Dungeon Conqueror, Redscale Destroyer, Phase Hunter, Lord of the Pale, and Tiamat's Bane.
