Bound Weapon Mastery adds four additional levels to the Mystic Binding perk, each of which creates a slightly more powerful version of bound weapons. The damage added per level is designed to emulate the effect of smithing, without the bother of powerleveling a skill you probably don't want as a master conjurer. A Bound weapon with Mystic Binding level 5 will be slightly more powerful than its physical Daedric counterpart tempered to Legendary sharpness (at 100 smithing skill + perk, no enchanting or potions).

Basic bound Weapons and the first level of Mystic Binding are exactly as vanilla. Mystic Binding level 2-5 requires Conjuration skill to be 40/60/80/100 respectively for each level of the perk.

The increase from one level to the next won't be very dramatic, but will allow your bound weapons to keep up in damage as if you were smithing a physical Daedric equivalent to Exquisite, Flawless, Epic and Legendary. This fixes the main problem, in my opinion at least, with bound weapons - the fact that they rock at low level but suck at higher levels.

The bound weapon spells will cost slightly less magicka than vanilla, because I had to balance out the base cost multiplier in the CK to keep them from costing a bajillion magicka each. The difference isn't huge, only about 20-30 magicka points, depending on the weapon.

*Updates*

New stuff in v2.0

The Dragonborn DLC is now required. Your game will crash if you don't have Dragonborn installed.

Spectral Arrow:
Spectral Arrow is a spell present in the vanilla game, but not used by anyone or anything. It was originally going to be the reward from Stalleo for clearing out the bandits in Trevas Watch, but was replaced with Detect Life before Skyrim was released.

The Spectral Arrow spell does 30 base damage, with +10 damage for each rank of Mystic Binding, up to 80 at rank 5, or 172 if dual-cast. For comparison, the Destruction spell Incinerate does 60 base damage, or 132 when dual cast, or 90 with both ranks of Augmented Flames, 198 dual casted. For balance, the stagger effect that the unmodded spell causes has been removed.

The damage ignores armor, but can be mitigated by non-elemental magic resistance. For example, an Orc in daedric armor would take full damage, while a naked Breton would take 25% less damage than any other race, because of their racial ability.

I think this should be balanced well enough, but I'm open to suggestions.

Using this spell against valid targets will gain XP towards the Conjuration skill. It does not benefit from the Soul Stealer or Oblivion Binding perks. There is now an optional beta file that adds support for these two perks.

SkyUI's MAG (magnitude) column reports the wrong damage. I'm not sure how to correct that.

The spell tome can be purchased from anyone who sells conjuration spells. NOTE: Edits two leveled lists, so use Wrye Smash (or a similar program) to build a bashed patch for mod compatibility.

Bound Weapons:

Damage on the bound sword/battleaxe/bow increased for ranks 2, 3, 4 and 5 of the Mystic Binding perks. Each of these ranks now add +5 base damage to each weapon.

Support has been added for the Bound Dagger added by Dragonborn. +5 damage added for ranks 2, 3, 4 and 5 of Mystic Binding. This extra damage is not visible in the inventory UI, but is applied as a damage health effect on targets, mitigated by their armor rating.
