[Spring-Loaded Blade] does not update if the disc waves proc Status Effects (meaning that you are required to get both stacks of SLB BEFORE throwing the disc out) and at Maximum [Spring-Loaded Blade] will only last 24 seconds (with both stacks) and another 24 seconds (with one stack) while the [Zenistar]’s disc at max 12x Combo will last 120 seconds. Thus, I chose to not include it in any of my [Zenistar] builds.
