|Two Upierczi consider their prey|
Active day or night they can be found out of their graves from noon to midnight. They must feed on a human before retiring for the night. During the day they look human, but when they are sleeping they appear dead. Often they sleep with their eyes open so they will know if they are being visited.
In human form they are physically one of the strongest vampires, having strength roughly equal to a Fire Giant (Str 22). They are also the vampire that most easily passes for human. They can eat and drink; though they must regurgitate it all later. After feeding they are even capable of sexual intercourse.
Upierczi can be detected by the drought they cause. Plants near them will wither and die. Small ponds will dry up and it will not rain in the areas they are in. If you can find a stream of running water then they can be killed with that.

The Upierczi drains blood from his victims via a sharp barb under his tongue. He uses his charming voice (same as the Charm Person spell) to lure victims into his embrace. He can drain 2 points worth of Constitution with this attack. The upierczi must feed on 10 points of con at least once per week.
People killed in this fashion rise up as a 6HD Upierczi under the control of the one that killed them.
The upierczi is a very strong and tough vampire. Piercing and slashing weapons have little effect on it. Swords, daggers, arrows, spears all will only do 1 hp point of damage per attack, and that is only if they are magical. Bashing weapons and blunt weapons such as maces and staves do normal damage. Swords specifically designed to kill vampires will do their normal damage.
In combat this vampire is very fast, gaining two claw attacks per round. It can also opt for a weapon and also get in two attacks vs the same opponent per round. The upierczi favors small light weapons it can conceal on it's person.
The upierczi is not repulsed by garlic, salt or anything natural. They cannot enter into a home unless invited, but they can use their charm voice to get that. They are however repelled by holy symbols and take 1d8 hp of damage from holy water. They are turned as Vampires by clerics.
The only true way to destroy an upierczi is drag it out of it's resting area before noon. Nail it to the ground with an iron spike through it's head and then set the body on fire. The body will burn quickly and then explode with all the upierczi's flesh becoming squirming maggots. These must be burned as well.
Like the Moroi, Upierczi consider themselves lords of vampire kind.
