Drafts of anything that I may come up with...

New Skill: Crystal Farming

Attribute: Knowledge

Time Taken: One hour to several months and more

Specializations: ...

this skill is used to seed, grow and take care of crystals in all their forms. It is more an Art than a practical method and requires a lot of time to use. The character knows how to grow crystals with various special effects - shape of the crystal, absorption and emission of a certain kind of energy, transformation of one kind of energy into another, shape of the emitted energy, resonance, etc...

... and this may give rise to a new force power:

New Force Power: Crystalize Force

Skill: Alter

Difficulty: varies

...

New Force Power: Focus

similar to Concentration, but uses a physical focus to manifest another Force Power. If Alter roll is made... this is just an idea...

Prerequisite: Concentration

Skill: Alter

Time taken: one round per force skill involved in the focused power.

Difficulty: Easy if the Jedi is relaxed and at peace; Difficult if the Jedi is filled with aggression, fear or other negative emotions; Very Difficult if the Jedi is acting on those negative emotions.

To use this power the Jedi needs a physical focus related to the power he focuses on. This physical focus is changed into pure force and effectively ceases to exist. The more meaning the object has to the Jedi, the easier it is to use it as a focus, the more meaning it has to another being or entity, the more difficult it gets.
