Investigation into Liches: Not a Lich of Knowledge
In the old library of the Red Wizards of Thay you have conducted an investigation into liches and found the following information:
Liches are the ultimate masters of undeath, usually a wizard, but also possibly a sorcerer or cleric. Liches are feared by mortal beings for their malign magic, their intelligence, and their willingness to embrace undeath for a chance to live forever (or rather, exist forever).
The process of achieving lichdom requires that the spellcaster construct a powerful magical artifact, a phylactery, in which the lich stores its life essence. As long as this phylactery is unharmed, the lich is immortal and reassembles if it was ever vanquished (this happens within 10 days after its apparent destruction). For this reason, liches take great care in protecting their phylactery from harm, they are known to employ decoys, traps, and other defences.
The most common physical form for a phylactery is a sealed metal box containing strips of parchment on which magical phrases are transcribed. Other forms of phylacteries exist, often small or tiny trinkets such as rings, amulets, or similar items. It can also take other shapes if the lich expends more gold and effort to make such alterations.
When the phylactery is created, the spellcaster transfers a bit of life force into the creation. While crafting the phylactery is taxing the physical strength of the caster, the materials and components can easily exceed 120,000 gp. Overall, creating a phylactery was a very daunting task for anyone of arcane power.
Liches are generally gaunt and skeletal with withered flesh stretched tight across horribly visible bones but can vary greatly in appearance depending on their age. Some appear as skeletons dressed in regal finery, yet others might appear to be nothing more than lepers. Bright pinpoints of (usually crimson) light burn in the empty sockets of those whose eyes had been destroyed or otherwise lost or were so old they had simply rotted away. The origin of a liches’ power can be determined by their eye colour, with dark crimson light being the most common one, corresponding to the ritual of Orcus, the Demon Lord of undeath. Eyes of light crimson are the second most common one, corresponding to powers granted directly by Bane, the Black Lord. There have been few sightings of other eye colours such as purple, grey, yellow and even blue, it is unknown what origin these colours correspond to.
Liches are great masters of necromancy and usually command many lower undead beings, the amount of undead a lich commands is only limited by the amount of corpses they can find, and what standards the lich might have. Most liches take a liking to skeletal undead, but there have been cases where cadaverous, spectral and (very rarely) sanguine undead have been favoured. A lich usually takes an appearance similar to their favoured undead.
A lich often haunts the abode it favoured in life, such as a lonely tower, a haunted ruin, or an academy of black magic. Alternatively, some liches construct secret tombs filled with powerful guardians and traps.
Should you face a lich in battle you best flee if you are caught unprepared, if you’re lucky the lich deems it unnecessary to pursue you. But if you draw a lich’s ire, escape is nigh impossible due to them having access to the Dimension Door, Fly and Greater Invisibility spells.Should you seek to battle a lich it pays to be prepared. A lich is fairly frail physically, but it has more than enough tools to end the life of any miserable creature foolish enough to cross it. A lich’s spellcasting is its most powerful tool, having spells such as Power Word Kill, Power Word Stun, Dominate Monster, Finger of Death, Disintegrate, Globe of Invulnerability, Blight, Dimension Door, Greater invisibility, and possibly many more at its disposal (remember, liches retain their spellcasting when attaining lichdom). Access to spells such as Death Ward and Counterspell is essential to any who dare fight a lich. Even if you come prepared for the spells, a lich can still harm you with its paralyzing touch, leaving you paralyzed and allowing its undead minions to chop you to bits.There is no way around it, a lich will usually never leave its lair, forcing you to fight inside it. While in the Lair the Lich can cause a targeted flood of negative energy to harm a living creature for massive damage and even use the spirits of the dead to restore his own magical energy. If you thought a single instance of Finger of Death was to be feared, wait till multiple instances start going out and those who fought alongside you will start fighting against you.Even if you survive the battle against the lich and destroy its physical body, as long as its phylactery is intact the lich will regenerate. To permanently slay a lich, both the lich and the phylactery must be destroyed in a very narrow timeframe, as the phylactery can create a new lich and the lich can create a new phylactery.
Despite all this, there have been instances of foolishly brave but very lucky Paladins defeating a lich without too much trouble, while the phylactery was (by dumb luck) destroyed by another group of disrespectful tomb robbers adventurers in a narrow timeframe. Causing the lich to be permanently destroyed.
