"Little girl,"
Stacy stood up and readied herself, she cast her magic defense magic and then drew out her staff.
"Who are you?" She asked, she had cast out her tier 10 defense spells, namely 10th Barrier and 10th shield. 10th barrier was a spell that enveloped the caster and would negate any magic below Tier 10. If a Tier 10 magic attack were to hit it, it would lessen the damage dealt and power by half.
10th shield also encompassed the caster but instead of protecting against magic attacks, 10th shield protected against the physical threats, namely anything directed at her from the physical plane. The barrier will stop any object moving at threatening levels from hitting her, forming a sort of wall wherever that attack would have struck.
However, each blow taken by the 10th shield would need mana to replenish and thus, 10th shield could actually kill its caster if the caster were to run out of mana in an effort to uphold its integrity.
