From top to bottom: The least, lesser, greater and siberys Mark of Detection

The Mark of Detection gifts the marked with the ability to ferret out danger whether from an ambush or a cup of poisoned wine.

House[edit | edit source]

The House Medani half-elves are the bearers of this mark. The house began as a mercantile organization and is one of the youngest of the Dragonmarked Houses. Despite the fact that they have been in operation for many centuries some of the older houses still view them as upstarts.

The Warning Guild is well known for its personal protection services and anyone holding a meeting with less than trustworthy business partners would do well to spring for a member from the guild to attend. Members of the house who do not manifest the mark often serve as sentries and guards.

Mechanics[edit | edit source]

Marks in 3.5e[edit | edit source]

In 3.5, the Mark of Detection was represented as a chain of feats for half-elves.

  • Least: Detect magic 10/day or detect poison 2/day; +2 on Spot checks.
  • Lesser: Detect Scrying 10/day or see invisibility 10/day
  • Greater: True seeing 10/day

Siberys[edit | edit source]

  • Moment of prescience 1/day

Marks in 4e[edit | edit source]

In 4th edition, the various levels of mark were simplified into one Mark of Detection feat that is available to any race.

Marks in 5e[edit | edit source]

In fifth edition, the Mark of Detection is a variant race option for half-elves which replaces some half-elf traits with a slightly different ability score increase, innate spellcasting, skill bonuses, and some spells added to any spellcasting class' list.
