I like playing melee rogues, and sometimes light armor doesn't cut it. I also like playing elves, so I'm very fond of the Ancient Elven Armor set. However, since it's only Tier 4, it can't compete with high-tier light armor, and the only top-tier unique medium armor sets in the game are Wade's Dragonskin sets which are 1) mutually exclusive from each other & 2) mutually exclusive with Wade's Dragonscale and Dragonbone sets.

This mod makes the Ancient Elven Armor set upgradeable to Tier 7 Dragonbone. The initial material of each piece will depend on your level when you acquire it.

Installation
Download the mod, then unzip the folder and place it in your override folder (usually found at Documents\BioWare\Dragon Age\packages\core\override).

Compatibility
Incompatible with any mods that modify

• gen_im_arm_bot_med_elv.uti
• gen_im_arm_cht_med_elv.uti
• gen_im_arm_glv_med_elv.uti
• gen_im_arm_hel_med_elv.uti
  

Important Note
If you've already gotten any pieces of the armor set, this mod will not alter them. In order to get the upgradeable armor piece(s), you'll need to download the AddItem With Console Improved mod, enable the console on your game, and then add a new copy of the piece(s) to your inventory. The additemwmat command can be used to specify a material higher than the default Tier 4 Veridium. You can then safely destroy or sell the old piece(s).
Similarly, uninstalling the mod will not revert the armor to fixed Tier 4 Veridium. You'll need to uninstall the mod and then use the console to create new copies.

Smaller Note
The chest piece, gloves, and boots won't change in appearance between tiers, due to the armor's unique skin. The helmet, however, will change color. If this bothers you, then I recommend Yonline2's No Helmet Hack.
