3000 volts
1500v From ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1: "When people are charged with static electricity, they can release stored energy to conductive objects such as doorknobs and electronic circuits. This transfer of energy is called an electrostatic discharge. Sometimes the electrostatic discharge causes visible sparks, but more often, it is both unseen and unfelt. Electrostatic discharges can damage ESD sensitive components used in modern electronics. Static electricity is a natural phenomenon that occurs in all climates and at all levels of relative humidity year round. Most people cannot feel an electrostatic discharge unless the static voltage is greater than 2000 volts. However, some electronic circuitry can be damaged by ESD that is less than 2000 volts. The damage can be done without people having any sensation of the ESD event. When a wrist strap is worn properly and connected to ground, the person wearing it will stay near ground potential."
Electrostatic charge can cause sparks, which may ignite flammable materials or gases, leading to fires or explosions. Additionally, static electricity can damage sensitive electronic components in devices and machinery, leading to malfunctions or failures. In some cases, electrostatic discharge can also pose risks to human safety, such as when a person experiences an electric shock.
Electrostatic discharge (ESD) tools are devices used to prevent damage to electronic components from static electricity. They are grounded tools that help to safely handle sensitive electronic components by dissipating any built-up static charge on the person using them. Examples include ESD-safe mats, wrist straps, and grounded workstations.
A wrist strap is a device worn on a person's wrist that is connected to a grounding point. It helps to prevent static charges from building up on the body by providing a path for the charge to flow to ground. This can help protect sensitive electronics from damage caused by electrostatic discharge.
Materials such as carbon fibers, anti-static additives, or conductive yarns can be woven into a polyester carpet to prevent a static charge from building up on a person walking across it. These materials help to dissipate the static electricity and reduce the likelihood of experiencing electrostatic discharge.
what is the minimum level of elecrostatic discharge that a person can normally feel? Per ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1 "Static electricity is a natural phenomenon that occurs in all climates and at all levels of relative humidity year round. Most people cannot feel an electrostatic discharge unless the static voltage is greater than 2000 volts. However, some electronic circuitry can be damaged by ESD that is less than 2000 volts. The damage can be done without people having any sensation of the ESD event. When a wrist strap is worn properly and connected to ground, the person wearing it will stay near ground potential."

Absolute discharge - yes Conditional discharge - when all the conditions are met and the discharge turns into an absolute discharge

The person getting baptised, for a start. That is the bare minimum. Normally the parents are also there, plus 2 godparents. Beyond that it is really up to the family, whoever they want to invite.
ESD stands for electrostatic discharge, which is a sudden flow of electricity between two charged objects. This is due to contact, an electrical short, or dielectric breakdown.
