Ati was once a kind and generous man, and you saw what became of him.

Vi vet att extrem användning av investeringar förändrar människor.
They are called Allomantic savants. Men or women who flare their metals so long, and so hard, that the constant influx of Allomantic power transforms their very physiology.
In most cases, with most metals, the effects of this are very slight. Bronze burners, for instance, often become bronze savants without knowing it. Their range is expanded from burning the metal so long. Becoming a pewter savant is dangerous, as it requires pushing the body so hard in a state where one cannot feel exhaustion or pain. Most accidentally kill themselves before the process is complete, and in my opinion, the benefit isn't worth the effort.
Tin savants, however... now, they are something special. Endowed with senses beyond what any normal Allomancer would need—or even want—they become slaves to what they touch, hear, see, smell, and taste. Yet, the abnormal power of these senses gives them a distinct, and interesting, advantage.

Dessutom påverkar skaparens skapelse sin personlighet.
Does the intent/personality of the Shard affect the personalities of the humans they create?
Det har en mycket liten effekt.

Så att svara på din fråga: "Kan det dock vara så att mindre belopp av Investiture fortfarande påverkar en person? Har inneboende nivåer av Investiture under det som en Shard påverkar människor?" Ja, den sliver (inte detsamma som en Sliver) som är underblåst under skapelsen påverkar människan. Genom att använda Investiture of Shard ändras en person ytterligare. Och att bli en Shard-fartyg ändrar individen mest av allt.
