Mystara, The Land Forgotten
Chainmail of Spellfire Defense
+3AC, +1 Fortitude, Reflex, and Will.
The armor can store up to 60 SL.
The armor grants an additional +1 AC for every 10 SL stored within it. The armor grants an additional +1 Fortitude, Reflex, and Will for every 20 SL stored within it. As a standard action, Aslan can transfer a number of Spell Levels from himself or any of his other storage items into the armor up to his Constitution score.
When Aslan is about to take damage, he can expend SL to reduce the damage taken on a 1 for 1 basis. This ability can only be used with Spell Levels from within the armor.
This chainmail was made from specially treated steel with crushed crystal smelted into it. This lead to the armors ability to store raw magical power as well as be strengthened by the power it was storing. The process used ended up with the armor being a pale gray matte color while empty of Spell Levels, but as the armor has more SL stored within it the links appear to brighten slightly, and to writhe into one another as if they were all woven from the same material. The links, when at full capacity, cease to be distinguishable as individual rings, and appear to be a moving, writhing, faintly glowing suit of pale gray metal with a slight golden tint.
