Demonite Fragment Uses and Applications

Half-Demon Race Unlock

Using a Demonite Fragment gives you a 30% chance to transform into the exclusive Half-Demon Race:

Advantages:

Increased Sword Damage output
Reduced damage taken from Power-based stats
Unique visual appearance with demonic characteristics

Disadvantages:

30% reduction to maximum HP
Cannot be acquired through normal race rolls

Race Tier Analysis: The Half-Demon Race ranks as A-tier in the current meta.
