I couldn't find anything posted on the forums about the special Lightsaber Crafting Tool that gives 20 Guaranteed Critical Experiments so I thought I would post my findings here if anyone else is looking for this information.
To clarify what the tool does, Critical Experiments means your experiment is guaranteed to be an Amazing Success roll. Using the tool does NOT consume any charges. The charges are only consumed when you run experiments. So you can still craft Refined Crystal Packs using this tool and you don't have to worry about spending any of your charges.
Ideally, you want to use the tool and get to the screen AFTER you put in the materials but BEFORE you start experimenting. This screen will tell you how well your assembly rolled. You are looking for an "Amazing Success" roll here. If you do not hit the Amazing Success roll, I would just cancel the crafting session here and try again. This way you aren't using any of your Guaranteed Critical Experiments.
As far as expending charges, this needs more testing. But here are my findings so far...
I put 4 points into damage and 8 points into efficiency and ran the experiment once. This consumed 2 charges from my tool.
I put 8 points into damage and 0 points into efficiency and ran the experiment. Then I put 3 points into damage and 1 point into efficiency and ran the experiment a second time. This also consumed 2 charges from my tool.
Based on my findings above, it seems like the tool uses 1 charge for experimenting on damage and 1 charge for experimenting on efficiency regardless of how many times you run the experiment? If anyone else has any more data please feel free to add.
Side note, you don't NEED this tool to get the best lightsaber. You can get the same results with a regular lightsaber crafting tool but you just have to get lucky with Amazing Success rolls.
That's all, short and sweet. Hopefully this helps someone.
