At 12X Combo Multiplier

Well Balanced between Critical Damage and Status Chance of 195.9percent (Approx 196percent) and 183.6percent (Approx 184percent) respectively.

Synergy

This is between the Heavy Attack wind up speed and 2x Critical Chance from Amalgam Organ Shatter & True Steel.

[Spring-Loaded Blade] stacks (due High Status Chance from Slash and Puncture) additional range upto extra +2 range to the heavy attack shockwaves range as well, totalling to 4.50m range.

If you are working your way upto a more forma build, I'd say try this after the first forma polarization.

Primary and Secondary Dexterity Arcanes for Additional Combo Duration (upto 15s when both present at Rank 5 each)

This is essential inorder to build Combo Multiplier at ease
