Transmute Mineral Oreverhaul

An overhaul of the vanilla Transmute spell.
This mod adds two new spells to replace Transmute Mineral Ore: one for turning Iron into Silver, and another for turning Silver into Gold.

Features:
- Concentration spells: The two new transmutation spells are now concentration-type, like the vanilla Flames or Healing spells, rather than the fire-and-forget casting type of the vanilla Transmute spell.
- Alteration level check: A higher Alteration skill level will result in a faster rate of transmutation for both new spells.
- Dual-casting support: If you have the Alteration Dual Casting perk, then the spells can be dual cast, which increases the rate of transmutation even further.
- Stability support: If you have the Stability perk (in the Alteration tree), then the rate of transmutation is increased by 50%.
- Replaced spell tomes: The vanilla Transmute Mineral Ore spell tome is found in two locations in the game: Halted Stream Camp and Ansilvund. This mod replaces the tome in Halted Stream Camp with the Transmute Iron to Silver spell, and the one in Ansilvund with the Transmute Silver to Gold spell.
- Lore-friendly environmental storytelling: Halted Stream Camp is a fairly rich iron mine, so the bandits occupying it have managed to dig up a decent amount; however, the fact that they've only managed to produce a single piece of silver ore speaks to the fact that none of the mages among their number are terribly skilled. Ansilvund is filled with mages and is led by Lu'ah Al-Skaven, a powerful necromancer who has raised the draugr in the crypt to work as miners, but they haven't found any significant amounts of ore yet, so the book lies on a table in the hope that they eventually will.
- Vanilla spell untouched: The vanilla Transmute Mineral Ore spell is still in the game and is not modified. However, both of the spell tomes that usually teach it to the player have been replaced with spell tomes from this mod, so if you have this mod installed you'll probably need to use the console to add the vanilla spell if you want your character to know it, or obtain it in some other way via a different mod.
- Doesn't require new save: You can install this mod for use with an existing save file. It even works if you've already been to Halted Stream Camp or Ansilvund and your character already knows the vanilla Transmute spell.
- Papyrus source code: The .bsa file only contains the compiled .pex used for the magic effect, but the mod's .zip file contains Papyrus source code file. It's fairly well documented if anyone wants to read it.
