Acording to the link on the donator page from the Symbol of the Blue Dragon, the spell effect for Form of Defense VII is:
6: Effect type: Screech by 1%
10: Effect type: Increase AC by 480
Using mystats the affect raises AC by 141
Form of Defense V on the link from the Red Resistance Stone states that it raised AC by 400, agian mystats reports 118.
I am just wondering if this is a mistake, typo, stacking issue or am I simply missing something. Obviously I purchased the item because of the AC boost, its not to big of a deal to me but curriosity has me now.
