The Eden Blitz is the cannon obtained from the crafting of 7 Dravite Chunks. It is a relatively weak weapon for its calibre, dealing only 10 ranged damage. It consumes Dravite Dust as ammunition and has infinite uses. It is a weak and expensive weapon, so it is not recommended to craft this weapon.
The mere fact that it is weak and expensive to craft weapon makes it pointless to obtain. Although it has infinite durability and a high rate of fire, the fact that it requires ammunition limits this advantage. A much more suitable weapon to obtain would be either the Queen of Fire or the Dravite Phaser.
