+# Understanding the Remaining Fields
+
+A dizzying array of fields exists that have not been covered above.  Many of these fields are quite self-explanatory, such as the level at which each class can use the spell, the deities allowed to use the spell, cast-on messages, etc.  This section is meant to cover the remaining fields as questions arise about their functionality.  Remember to reference the information on [spells_new](https://github.com/EQEmu/Server/wiki/spells_new) found on this wiki, and the information contained in the [spdat.h](https://github.com/EQEmu/Server/blob/master/common/spdat.h) source file.

+## Reagents
+
+Spells that require reagents have items (by Item ID) listed in the components fields (component1, component2...component4).   Examples of such spells would be Elemental: Earth (default Spell ID 401), which requires Item ID 10015 - Malachite, or Diamondskin (default Spell ID 394), which requires Item ID 10028 - Peridot.  Some spells require a focus item, but do not consume the item when cast, such as Flame Lick (default Spell ID 239), which requires a 10307 - Fire Beetle Eye to cast, but does not consume it.  Note the relationship between the component fields, the component count fields, and the NoexpendReagent fields, which utilize slots--just like Spell Effects discussed above:
+
+**Slot** | **Component** | **Component Count** | **No Expend Reagent**
+----- | ----- | ----- | -----
+1 | ItemID | Count of the ItemID | Used as Focus item, or "Needed But Not Used"
+2 | ItemID | Count of the ItemID | Used as Focus item, or "Needed But Not Used"
+3 | ItemID | Count of the ItemID | Used as Focus item, or "Needed But Not Used"
+4 | ItemID | Count of the ItemID | Used as Focus item, or "Needed But Not Used"
