i am force but need a skill build for maxing compound tech damage, TEC Power Elemental Weakness Various Skills, including Mastery Skills such as Light Mastery I and Flame Mastery I. Potentials that boost damage. Potentials that boost Technique damage do not affect Fused Techniques. Talis Tech Bonus does not affect Fused Techniques. Skills and Potentials that reduce Charge Time do not affect Fused Techniques.

For strongest compound damage you want go Force/Techer. Max all element masteries, get the Shifta and elemental weak hit from techter tree. Cram as much tech has you can into your rod. Make sure you have Shifta before using and zanverse before using

Edit: go nemesis or atlas for your rod, both have great potentials for boosting damage
