He looked at her and laughed. "Hah! Is that all you've got? Come on girl, try harder!"
"Okay, you asked for it," came Bloom's reply as she mustered all her strength into producing one ultra-powerful shot. A ball of energy materialised between her hands, growing quickly in size and intensity, burning so bright that it was impossible to look at, until finally she let it fly. It screamed towards him at incredible speed, leaving a scorching streak of flame in its wake.
Tegryn readied himself, bringing his hands together out in front of him. With an evil smile on his face, he cried out "Magic Mirror!" He slowly moved his hands apart, revealing a shimmering white disc between them. The fireball struck it with full force, but was instantly deflected back at full speed by his mirror spell.
"What?" said Bloom, startled. Surprised by this unexpected counter-attack, she tried to evade her own fireball but was sent flying by its sheer ferocity. She groaned as she tried to pick herself up off the floor, her outfit smouldering from the heat.
Tegryn's manic laughter rang through the chamber. "What's the matter - weren't you expecting that?" he taunted. "You lot have hit me with your best shots, but I'm still standing - so what are you going to do NOW?""
Things were getting desperate, but despite the despondency creeping into the fairies a flash of inspiration came to Mimi. She whispered to her sister. "Wait a minute... nothing's getting through his shield spell - except sound!"
A smile broke out across Nini's lips. "So you're thinking what I'm thinking?"
"As always!"
The twins clasped their hands together and faced Tegryn. "DOUBLE SINE WAVE!" they cried as they let rip with their trademark attack.
Tegryn clasped his hands over his ears in a vain attempt to block the ear-splitting noise, but it was hopeless - the pressure of the sound was too intense. It felt as though his head was going to explode... but amidst the agonising noise, an idea came to him - raising one hand, he cried out "Sound Bubble!" and all fell silent as the sisters' attack was neatly contained in the soundproof spell. The twins called upon every ounce of their power, but to no avail - try as they might, they couldn't penetrate it.
"Heh!" he sniggered, staring at Musa. "Thank you so much for teaching me that spell - I always knew it would come in handy!"
"I wouldn't be so sure of that. You may be more powerful now, but that spell isn't - it's not meant to be used in combat, as you're about to find out." Musa said as she walked over to the twins and took Nini's hand in her own. "Ready?"
The twins nodded.
"TRIPLE SINE WAVE!"
The three Melody fairies unleashed their attack with every reserve of their strength. Tegryn coped easily at first, but he was soon struggling to hold his defences together. He strained to keep the sound bubble intact but it soon shattered, and once again he was floored, at the mercy of the piercing noise of their audio assault.
As he knelt on the floor in agony, Bloom shouted out "Okay, he's down! This is our chance!"
The final phase of the plan was about to take place.
