Runic sigils called Marks are the defining feature of Nephilim life. Inscribed on the body using a stele — a ritual instrument of celestial silver — these runes draw on the power of the angelic script Raziel left behind. Each Mark carries a specific purpose: Iratze heals, Enkeli strengthens, Voyance sharpens the sight. A Nephilim's body accumulates Marks over a lifetime of service, and the most experienced among them wear their history in layered script across their arms, throats, and hands.

Not every body can bear a Mark. Ordinary mortals who receive them are overwhelmed — the divine power tears through flesh unprepared to hold it. The blood of Raziel is what makes a Nephilim's skin a vessel. It is both their gift and their distinction from the mundane world they protect without thanks, and often without recognition.

Your skin can bear the sacred Marks of Raziel. You learn one Mark of your choice from the Mark Runes list below. You learn an additional Mark at 3rd level and again at 5th level. Marks take one bonus action to apply. Once you use a Mark's magical effect, you must finish a short or long rest before using that same Mark again, unless the Mark is passive.

Your body mends with inhuman speed. When you roll a Hit Die to regain hit points during a short rest, you may reroll the die and take either result. Additionally, you can stabilize yourself when at 0 hit points at the start of your turn, as though a creature had administered first aid to you.

You have resistance to necrotic damage. You also have advantage on saving throws against being charmed or frightened by fiends and undead.

Your celestial lineage grants you eyes that pierce deception. You can see through magical illusions and glamours as if under the effect of a see invisibility spell, though you cannot see invisible creatures — only hidden or disguised ones. Additionally, you have darkvision out to 60 feet.

As a bonus action, you can call forth a blade of concentrated angelic light. It counts as a finesse, light melee weapon that deals 1d6 radiant damage, and is considered magical for the purposes of overcoming resistance. It vanishes if you drop it or are incapacitated. You can also dismiss it as a free action.

You can speak, read, and write Common and Celestial.

A Nephilim matures at the same rate as a human child and reaches adulthood around twenty years of age. After that, the celestial blood slows the body's aging considerably. Most Nephilim live to roughly two hundred years, retaining physical vitality well into their later decades. This longevity is both blessing and burden. They watch mortal companions age and die. They carry grief longer than any human could. The oldest among them carry it in their eyes — a depth of loss that no number of Marks can cover.
