Unforeseen Circumstance

Merlin paced around the numerous bookshelves and eventually locked his eyes on Thunder-type spell.

Thunderbolt and flames were both violent enough to produce an equally terrifying force. Hence, Fire-type and Thunder-type made the most compatible Offensive spells.

Merlin already possessed Fire-type Fireball, hence he needed to choose another type of Offensive spell. It seemed that the most appropriate choice would be a Thunder-type spell.

There was an extensive selection of Thunder-type spells in the Dark Magic Region so Merlin had to choose with caution. He wanted a spell that was greatly powerful and was able to cover an expansive attack range. Knowing what he wanted helped in narrowing down his options.

Finally, Merlin made up his mind on a spell named Thunderbolt Net. The distinguishing trait of this spell coincidentally matched with Merlin's requirement.
