* The removal of MCore has forced me to postpone the API for one more release, as it has drastically changed how it will work
Version beta 5.37.006
*The main config file has been moved - it is now at /config/ArsMagica/AM_Main.cfg. The format hasn't changed so you can copy the old one in and rename it.
*This update requires an MCore update.
*One of the biggest problems that I have had with Ars is the inability to find those last few spells. To that end I have implemented a new block to help with that. The Spell Research Table. Simply toss in 3 of the same essence (which determines the affinity of the researched spell), any lost journal fragment, a feather, and an ink sac (shift click will show you where to put them). The block will go for 3 minutes, then give you the recipe for a spell you don't already know within the specified affinity. This process currently seems "blah" to me though, and I will likely change it. In addition, the block needs essence power, 100,000 to be exact, and will not start until it has all of it.
*Added Mana Batteries - these can be placed anywhere and will draw power from a nexus when powered by redstone. They hold up to 250,000 power, and are recognized as a nexus by other power interaction blocks, though you must recharge them using an actual nexus. They can be eaten by the nexus as well, and will charge it with their internal capacity (or if empty, the cost of the materials). They can be fabricated.
*Added a new spell - Radiant Shield. You emit a burst of light that repels enemies, deflects spells and arrows (most of the time), and on augmented, lights the undead on fire. The particle effect doesn't disappear properly in SMP - use it sparingly there. A re-log will remove any artifact particles.
*Ars Magica power is now configurable! When launching for the first time, Ars will attempt to calculate power values. Anything it can't find a power value or recipe for will be outputted to the power config file under /config/ArsMagica.AM_Power.cfg. It is sorted by mod internally. There's no need to set anything that is prefixed with "tile" - that shouldn't be in there, and won't have any effect.
*Added the lectern block. This accepts written books and the Thaumonomicon and will display them. Right clicking the lectern will open the UI of the item inside. Shift + RC to retrieve your item (or break the lectern). Very useful for the TC lab!
*For those of you who have access to beta particles, there is a new one called "radiant".
*Mobs can be individually disabled via config
*Spell recipes in the inscription table should display correctly now.
*Hooked in with Forge ID/Block reassignment - this should help with many of the ID conflict issues people were having
*Added deficit crystal - this is something for a neat project Tofski and I are working on. Shhh! I wouldn't throw it into your nexus...or would I?
*I've postponed the API until the next update - it's not ready, but I figured I would give you the rest for now 
----

**Starting from average level 15 you will start to see infrequent normal casting mages. This chance will increase as the average mage level of players increases (max 30% chance).
**Starting from average level 30 you will start to see infrequent Augmented casting mage NPCs. This chance will increase as you get closer to 50 (max 40% chance). Normal casting mages continue to be more common as well. Be prepared.
