"SIERRA'S LAST STAND!"
The true ultimate skill of this boss, but also the most terrifying one.
And the reason was right in front of Stark, although he still decided to use [Perception] on it.
...
[Skill: Sierra's Last Stand]
[Description:] Sierra gives up shooting arrows to charge many more, and if she successfully manages to cast this skill after a while, then hundreds upon hundreds of arrows will appear to surround the enemy, leaving them with no real escape.
[Note:] This is an unavoidable attack, so eliminate her before she does that.
...
'...' Stark didn't say anything, his anger was at an all-time high since he knew that he was pretty much fucked, and the worst part was that look on Sierra's face, one that told him she was confident that she had won now.
