Copper Phoenix Sigil Edit
It was a simple enough design made by Corin. The back has a few runes etched into it and on the front was the symbol of the phoenix. It was about the same size as the Lorian Heights Academy issued shield sigils. The major enhancement to the design was that they had a higher capacity and they were self-recharging, taking about 1 hour to completely recharge.
Silver Phoenix Sigilshield sigil Edit
The next iteration in Corin's design. He further upgraded the shield giving twice the capacity of the copper phoenix sigils and four times that of the Lorian Heights Academy issue shield sigils. He added a higher tier version of the self-recharging rune to maintain the recharge time of 1 hour. The most significant upgrade was a regeneration enchantment.
