There they saw a black dragon which was having a battle with a golem(A large creature made of stones that had a incredible defence and also had a good offense) both of the monsters were strong enough to fight a 4th circle mage on equal terms. Amon started thinking of a plan to on how to defeat the beasts.
The plan he thought of was that they should wait until one of the beasts get defeated. As because of the battle the other beast would be in an weakened state so it would be the perfect time to end the the beast.
They waited for the battle to end so they could execute their plan. They waited for hours for the battle to end. Then Theodore asked "Amon I think we should head back home as it is getting dark and if we stay here longer we may get attacked by wild magical beasts". Amon couldn't disagree with. Theodore's statement but also he couldn't think of opportunities like this to gather dark essence(Dark essence is the impurities of living beings that resonant inside them.)
It helps dark magicians to get stronger but the catch was the living being should be dead.
When he was still thinking about the situation the golem had been defeated by the dragon. Amon thought this is the perfect opportunity and started the attack with Theodore and the fenrir cub. The dragon didn't even know that he was ambushed before getting hit by a ice boulder on the back.
The attack didn't even scratch the dragon it was just a 1st circle spell. After hitting the dragon and distracting him Amon shouted Theodore do it now following the order Theodore casted" vasgu"meaning( soul bind) it would affect the soul of the dragon for 1.27 seconds not allowing it to move. After Theodore casted the spell. Amon used hikato that would summon a sphere of pure darkness the spell would devour the living beings body when it hits.
When the dragon got sucked in the sphere they thought it would stay in there for some time to kill it but in the void the dragon had absorbed the Golem's core reaching 5 circles escaping the spell. Amon was surprised that it managed to escape the spell.Amon was still thinking about killing the dragon he knew it was still injured from the previous battle with the Golem so he decided to cast everything he learnt into one spell casting "minpa ma drang.meaning (one with darkness)after casting the spell he covers himself with pure darkness and also forming a sword in his hand all his physical states had been boosted also almost with a endless supply of mana but the catch of using this spell was that he stayed in an motionless state for a long time.
With just a slash of the sword the dragons right arm got decapitated the dragon knowing that he will die no matter what he used his most powerful move"mi khongtro"
Meaning (Fire's rage) after casting he exuded fire from every part of his body.
Both of them clashed and the battle lasted for 2 minutes the dragon only managed to cut Amons hand before getting sliced into meat chunks. After that he returned into his original form and absorbed the dark essence reaching the 4th circle soon he collapsed to the ground motionless.
