The constraints and vows under the Conditioning Oath increase the power of "thoughts", and the master who taught Kurapika telekinesis pointed out that it is impossible to manifest chains that will never break, but it is possible to manifest something close to infinity. From episode 47 of the anime (2011).

Example: Kurapika - Bondage middle finger chain. Can only be used on members of the Phantom Brigade, and if it is used on someone other than a member of the Brigade, the user's heart will burst.

Example: Franklin - two-handed machine gun. Originally, you didn't need to cut off your finger to shoot a bullet, but because the user subconsciously thought that "the bullet shot will be stronger after cutting off your finger", this is what happened.

Restricting

Make rules, swear in your heart, and stick to them, the more difficult the rules, the more powerful they will be.

If the ability to read in ordinary times is compared to addition, then the ability to read according to the rules is multiplication, and the power will be multiplied.

where P is the attack power, N is the telekinesis, and D is the difficulty of the constraint.

default

Restraint and oath are unstable dìng's big move - a double-edged sword.

Breaking the oath may result in the loss of telepathy due to backlash.
