Ruin

"Guess we have to fight huh." Wren said, looking annoyed. She wanted to go look for Vell. "guess I will lash out at you guys." She moved so fast it looked like she teleported. Her mana claws sliced through one, causing it to disappear. 'that didn't feel right, my attack went through it?' 

The monster reappeared behind her and tried to catch her off guard but her senses were too sharp for that. She kicked it without turning her body but the same thing happened again. 'strange, its like hitting air.'

She was confused. Her attacks went right through the sand demon like it was made of air. Even when she kicked it, nothing happened.

"Guys, physical attacks don't work!" she called to the others. "They're like ghosts!"

Regina quickly analyzed the situation. "They're made of sand and wind! We need to use magic or elemental attacks!"
