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: speed-growth, specific purpose crystals, etc.

This skill can be 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 also knows how to grow crystals with various special effects - the crystal can have any shape, it can absorb and emit energy (usually sound or light), it can have resonance effects, etc. It can be used as an art form, but it also gives knowledge about the various kinds of crystals in the galaxy, but may have an advanced skill: Crystal Engineering used by the Skek to create weapons and other Crystech^(TM) equipment.

... 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. this is just an idea...

Prerequisite: Concentration, Telekinesis

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 concentrates on an object somehow related to the power he focuses on. There is no hard rule about which objects are valid and which are not, because it strongly depends on the Jedi using this power. Usually every Jedi will develop an own style but the GM is the ultimate judge. In general, 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... The physical focus is changed into pure force and effectively ceases to exist in its material form.
