Bind Soul

When a creature with a Challenge Rating of 1/4 or below dies within range of you, you can capture the creature's soul inside the mundane item used as part of the spell. The item becomes a sentient item with an Alignment and an Intelligence, Wisdom, and Charisma score equal to the creature that died. The sentient item communicates by telepathy with the creature carrying or wielding it. The sentient item knows what it knew while it was a creature, and so can answer questions as if the creature was answering, however it is under no compulsion to offer a truthful answer if you are hostile to it or it recognizes you as an enemy. The soul can be freed by the casting of the spell "Dispel Magic" or a similar effect onto the item. While under effects such as the spell “Antimagic Field” that would suppress magical effects, the item can not communicate with its wielder for as long as it's under the effect. If the item is destroyed, the creature’s soul is also destroyed.

At Higher Levels. When you cast this spell using a spell slot of 2nd Level or higher, the Challenge Rating of the soul you can capture increases by 3 for each spell slot above 1st
