Nether Portal created by Kreknorite Meteor, note the blaze under it
A Kreknorite Meteor is the rarest meteor of the three (Meteorite, Frezarite, and Kreknorite) that you will encounter. When it crashes, it may also spawn a Nether portal with accompanying Nether Brick and Glowstone. However, it usually brings some of its mobs with it, the most common being Blazes. The Nether portal will only appear if the meteor that fell is bigger than the smallest type of meteor (There are 3 sizes of meteors, thus Kreknorite must be size 2 or 3 to spawn the portal). It creates lava and Kreknorite blocks, which then turns into obsidian after it cools.
A Diamond pickaxe is required to mine to Kreknorite blocks. You will not always get Kreknorite chips, as the drop chance is random. You can increase this chance by using the Fortune enchantment.
Kreknorite chips are used to craft Kreknorite Armor and Kreknorite Swords, and the armor provides you with complete immunity to fire, allowing you to stand in fire and swim in lava. The sword has a unique ability that sets fire to whatever mob you hit with it (much like Fire Aspect).
Summoning
A Kreknorite Meteor can be summoned using a Kreknorite Meteor Summoner, and is the most destructive as it will both create lava and fire, as well as spawn Blazes.
Warning:
The Kreknorite Is one of the Rarest Meteorites in the game, sometimes falling in small qualities in dispersed spots throught your world. Often times Kreknorite crash sites are surrounded by skeletons and Are in a crater averaging 4 blocks deep. A nether portal will spawn at larger crach sites.
Tools & Armor:
You can craft a sword out of armor that gives a special buff: Fire Resistance. This is especially useful if you are one who relies on the meteor mod for armor as you can mine up active chips without getting burned. Kreknorite Also Allows you to make a Sword that gives the enemy max 7 battle damage from fire per hit.
