PteraXpansion

PteraXpansion is a new mod adding multiple additions Mojang will never add, such as: an End Update, a Redirector, an Auto-Mining Block, and much, much more.

Wasteland (Spoiler)

In the end, the only vanilla island that still generates is the central dragon island. However, there is a new biome, known as... The Wasteland, this biome is filled with Blazes, Blood Slimes, and Black Blazes. You may also find Grimstone Boulders and Obsidian Obelisks

Blood Slime

The Blood Slime attacks an mob/player when that mob/player attacks something, even if the victim the mob/player attacked was not the Blood Slime. He gets stronger each time he kills a mob/player. Blood Slimeballs are dropped from this mob.

Combining a Blood Slimeball with a stick makes the agility gadget. Which can then be combined with another stick to make an Agility Gadget with Long or with an Ender Pearl so it makes an Agility-Gadget with Ender-launch, you cal also combine the 2 together.

Black Blaze

The Black Blaze has a shield. You can break his shield or attack him from behind or from above. He does have a cooldown phase where he makes all nearby blazes aggro at you while he is under a cooldown.

Miner Block

is a new block which based on the side of the block it is placed on, will mine a specific side. It is activated with redstone

Redirector (Spoiler)

It will turn around until it looks at a player or Iron Golem, when looking at one, it will cause all nearby mobs (even passive ones) to attack the player/Iron Golem, only mobs that are tamed to the player are unaffected
