Thought of another one :
Divining Rod :
mode 1 : from 3x3x3 blocks to 5x3x3 blocks for 16 emc.
mode 2 : from 16x3x3 blocks to 10x3x3 blocks for 32 emc.
mode 3 : from 64x3x3 blocks to 20x3x3 blocks for 64 emc.
Philosopher Stone :
Remove free enchanting on tmi cheat mode, enable free enchanting on creative mode, make the user gain or lose levels on survival mode.
Also, thinking about the transmutation process of EE, I feel that the player should go through numerous stages of different transmutation items before reaching another one. Currently too many are skipped and only fullfill a limited purpose, hence the balancing suggestions on first post.
-Philosopher Stone : allows basic mutation of material blocks to a fixed other type of material block by rightclicking. it can transmute iron to gold and gold to diamond, it can also transmute coal to higher fuel levels.
-Gem of Eternal Density : automatically "eats" most items of EMC value in your inventory or in a chest to upgrade them into a material of higher EMC value. These materials are Iron, Gold, Diamond, Dark Matter, Red Matter.
-Mercurial Eye : It can transform any blocks into any other block, difference in EMC is taken from or given to the Klein Star inside. Thus Allowing to easily absorb natural blocks like wood and clay to charge the kleinstar or feeding it blocks of metals and gems.
-Transmutation Tablet : Allows all items with an EMC value to be transformed into all other items with an EMC value, As long as fuel and everything else aren't mixed up. Allows charging and uncharging klein stars from and to items. Once an item is used once, it is memorized by the transmutation tablet and can be crafted to. EMC is not permanently stored. EMC stored is same at every transmutation tablet but different for each person.
-Energy Condenser : Allows transmuting on a giant scale, everything inside the chest with an EMC value will be eaten and transformed into the item that is put in the topleft slot. Does not memorize items like the transmutation tablet. Cannot create anything worth more then 1 million EMC. Does not allow usage of kleinstars. EMC is permanently stored, EMC stored is different at each energy condenser but same for each person.
I'd like to see people use the first three for transmuting before moving on too the next level, transforming any item into any other item is very overpowered if it is something that you can achieve with only 7 diamonds. which should be getable within an hour using the divining rod.
