Flinch Free skill Kinsect mechanics
If you create an insect glaive build with 3 points in Flinch Free, then a triple kinsect buff increases Earplugs, Tremor Resistance, and Wind Resistance by 3 points in each category. Customizing your decorations to include Flinch Free 3, Ear Plugs 2, and Wind Resistance 2 will max out Flinch Free, Ear Plugs, Wind Resistance and Tremor Resistance. Works great with Ruinous Catastrophe because slots are more available.
Flinch Free 3 and Ear Plugs 2 is typically my build to provide me with Flinch Free 3, Ear Plugs 5, Wind Resistance 3 and Tremor Resistance 3 when the kinsect is triple buffed. Power Prolonger further adds to the build if you struggle to maintain enough uptime on the triple buff.
