Mined only in the Mournland in and under the Field of Ruins, mournlode is something of a rarity, and considered by many churches to be an ideal tool for combating undead manifestations. When mined, this iron ore has a mottled purple color, resembling some awful blight. When it is refined, it takes on a more vibrant silvery hue, streaked with veins of purple. In fact, various grades of mournlode exist, each with a slightly different appearance. To date, purple mournlode is by far the most well known (to the point where it is often referred to simply as “mournlode”).
Many people (including members of a number of good-aligned organizations) are confi dent that mournlode is touched with a protective presence, and they use it to make armor, holy symbols, weapons, and other implements. Mournlode has the same weight and other physical characteristics as iron (hardness 10, 30 hit points per inch of thickness), but displays special qualities depending on the type of item it is forged into.
A mournlode weapon overcomes the damage reduction of undead creatures as if it were crafted of either cold iron or alchemical silver, whichever is more appropriate. Mournlode armor grants the wearer a +1 resistance bonus on saving throws against any spells, spell-like abilities, and supernatural abilities used by undead.
A character who uses a mournlode holy symbol to turn undead deals damage equal to her turning level to undead affected by the turning attempt. For example, a 9th-level paladin (effective turning level 6th) using a mournlode holy symbol would deal 6 points of damage to any undead creature she successfully turns.
A mournlode weapon or suit of armor costs an extra 700 gp. A mournlode holy symbol costs 400 gp. Items without metal parts cannot be made from mournlode.
