"Anna, you need to take a break!" Layla yelled at her, all the while shooting the undead with a crossbow, "Using mana potions might fill your mana, but won't regenerate your stamina."
"Just... keep shooting..." Anna replied in her tired voice.
Hundreds of undead kept charging at them. With no place to back away, this was their final stand. A dozen of them against an endless horde of zombies. As if these odds weren't enough, more troublesome situations kept arising.
Ideally, it might seem as if Anna's flames were the perfect counter for the undead. But the reality wasn't so simple. Yes, Anna's phoenix flames were more than enough to kill the zombies, however, she couldn't continuously spew the flames for long periods of time.
Not only would her body heat up exponentially and she would drain her stamina and mana, but the oxygen around her would also burn up fast as well. Thus she would either die of over-exhaustion or suffocation.
