Mark of brotherhood

Mark of brotherhood was a spell used by dwarven clerics.

Effects
When cast, a glyph appeared on each hand of the caster. One glyph was the symbol of the caster's clan, and the other the caster's holy symbol. The glyphs became invisible and were only visible to those dwarves who had the same glyphs. The glyphs were permanent, but they vanished if the caster committed a serious offense against their clan and/or clergy. If such a thing came to pass, the glyphs flared with a brilliant light and seared the caster's hands, causing them great pain and leaving behind scars. The scars were permanent; no amount of healing could remove them. The only way to remove the scars was if the caster made amends for their offenses.

Components
In addition to verbal and somatic components, this spell required as a material component a coin made from steel that had the caster's clan symbol on one side and their holy symbol on the other. The coin was consumed by the spell.
