Sorry to see you go Rtron. Let me know when things get better and you can return once more.

Also here is how anti alchemy works. It is not some magic. It is a liquid that is often laced on blades on filled in bullets. Once this liquid enters the blood stream of an alchemist it makes the use of alchemy very difficult. So things like teleworking and healing become far too tedious to use.
