This mod enables anything that's recognized as a shield to parry Projectiles such as Snowballs, Ender Pearls, Fireballs including Blaze's and Dragon's Fireballs, and Arrows. You can still parry fireballs by hitting them with your sword.
There is a 2-second window after raising your shield where you can deflect projectiles that hit your shield. This can be changed in the config file. Executing a parry not only does this, but your shield will also not take damage.
It also adds an enchantment called Rebound that increases this time window for parrying. It has a maximum level of 5 but this can also be changed in the config. By default the bonus percentage is 25%, so each enchantment level adds an extra half-second. This means the time bonuses totaling 2.5/3/3.5/4/4.5/5 seconds respectively. It can be configured to be a treasure enchantment, making it only found on enchanted books in loot chests and from villagers.
What works as shields to parry projectiles, but not exclusively, are:
- Minecraft's Wooden Shields
- Immersive Engineering's Heavy Shields
- Tinkers' Construct Battlesigns
- Thermal Foundation's Shields
There is an Entity Type tag list parry:projectiles_parrying_disabled for any modpackers wishing to disable parrying for select projectile entities, and allow normal shield behavior to happen instead during impact.
