Sound Interactions

** Reactive Blocks — Version 1.1.0**
Sulfur Update
The Sulfur Update adds new Sulfur-related block reactions and a new enchantment.
New Sulfur Reactions
Sulfur Block → Nausea
Potent Sulfur Block → Nausea II + Slowness
Cinnabar → Hunger
(It sounds like a cinnamon roll, so naturally it gives you hunger.
also it is very toxic and contains mercury.)
** Filtration**
Filtration is a new helmet enchantment that disables effects of Sulfur-related blocks.
Because apparently breathing sulfur isn't good for your lungs :C.
** Bug Fixes**
Soft Step doesn't deal damage to attackers anymore.
Don't ask how this happened.
