hi
A sword
It was a normal sword, but a dragon blessed it with his fire and it became very powerful
you have to defeat the mechanical dragon.
the 4 golden weapons
It is said in the third book how they created the sword. The sword may have caught fire because first he was took part in making it and second fire in ancient language is Brisingr. thats not exactly true Rhunon believed that eragon may have discovered the true name of the sword and because he took part in forging it
Sword of fire, nun-chucks of lightning, shurikens of ice and scythe of quakes
because in the nijago universe the strongest of all creatures are the dragons, and the most powerful type of dragon is the FIRE dragon. Legend of Zelda rules, thank you and goodnight.
For the Shurikens of Ice, Dragon Fire Sword, Nunchucks of Lightning, and Scythe of Quakes, its the Dragon Fire Sword, there are only 2 sets to get it, one is $19.99 and the other is $119.99...I'm getting it from eBay, I already have the Scythe of Quakes, and I'm getting the Shurikens and Nunchucks for Christmas :)
Drink an Anti Fire potion. It protects you from dragon fire for five minutes just as well as an anti dragonshield.
You only get pure fire dragon when breeding a fire dragon with a pure dragon. A pure dragon can be bred with two legendary dragons.
