When I started playing skyrim years ago I was very frustrated with the magic system. One of the reasons was the short duration of most buffs and other spells. After many deaths because my oakflesh, flame cloak or bound sword expired mid combat I decided to make this simple mod.

When not playing as a mage we don't need to worry about our armor or weapons suddenly unequiping themselves, so why should the squishy cloth wearing mage have to constantly worry about it? To me it was a question of balance. No spells are replaced, longer duration version of existing spells were added with proportionally increased mana cost. All spells have their own spell books, and the books are added to the vendors leveled lists.

Here is the list of added spells:

• Dragonhide (5min)
• Oakflesh (5min)
• Oakflesh (10min)
• Stoneflesh (5min)
• Stoneflesh (10min)
• Ironflesh (5min)
• Ironflesh (10min)
• Ebonyflesh (5min)
• Ebonyflesh (10min)
• Flame Cloak (5min)
• Flame Cloak (10min)
• Frost Cloak (5min)
• Frost Cloak (10min)
• Lightning Cloak (5min)
• Lightning Cloak (10min)
• Whirlwind Cloak (5min)
• Whirlwind Cloak (10min)
• Bound Dagger (10min)
• Bound Sword (10min)
• Bound Battleaxe (10min)
• Bound Bow (10min)
• Candlelight (5min)
• Candlelight (10min)
• Magelight (5min)
• Magelight (10min)
  

Requirements: I added versions of spells added by the Dragonborn DLC, so it is required. I won't be releasing a "vanilla" version since by now the vast majority of players have all the DLCs.
