There are four possible general armor enchantments available in Minecraft v1.6.x:
- Fire Protection
- Blast Protection
- Projectile Protection
As discussed elsewhere, stacking different enchantment levels of these on different pieces of armor can maximize the damage reduction from different damage sources (general, fire, explosions, arrows, etc.). However, wiki sources also mention that Fire Protection additionally reduces the time spent aflame, and Blast Protection reduces the knockback from explosions.
Does Projectile Protection reduce the knockback from projectiles?
Additionally, does the knockback reduction offered by armor enchantments and the burn time reduction offered by Fire Protection scale with the enchantment levels, and is there a cap?
What is a specific explanation of the complete effects afforded by these enchantments, beyond the EPF damage reduction values?
