A simple and HIGHLY configurable mod that adds a new defense reducing effect to the kunai from Caverns and Chasms and whatever mob or projectile you want!
⬇ Download on ModrinthAS OF 1.2 THIS MOD NO LONGER REQUIRES CAVERNS AND CHASMS AND BY PROXY BLUEPRINT TO FUNCTION!
This is a standalone mod that includes the crumbling effect and functionality from my other mod Valcon.
When a configurable list of mobs or projectiles hurts another entity or player, they will inflict the crumbling effect which reduces their armor points by a configurable percentage, for a configurable amount of time, and will optionally display custom particles and or play a sound when the effect is over. The following config options and their default values can be found in: config/crumbling_kunai-common.toml
Crumbling inflictors: caverns_and_chasms:kunai
Crumbling armor penalty: 50%
Crumbling length: 10 Seconds
Crumbling particles: True
Crumbling icon: True
Crumbling sound effect: True
