1.18.2 fabric, spellbound 1.9.1
Spark profiler reported that net.tigereye.spellbound.enchantments.protection.HeartyEnchantment.onTickAlways() is negatively affecting performance while I had already disabled the hearty enchantment.
I guess it would be more performance-friendly to stop ticking when the hearty enchantment was disabled.

Closed as moot; Hearty no longer uses a global tick as I have found a better way to detect and handle the stat change.
