FFXIV: A Realm Reborn.
Rated T for Teen by the ESRB for Violence, Blood, Sexual Themes, Partial Nudity, Language, Use of Alcohol and Tobacco.

It doesn't Specifically name what your talking about, but you are made aware that there is Blood and Violence in this game. With that in mind, you should be mentally able to handle that in all shapes and sizes. If you need a trigger warning, you probly shouldn't play a Violent Videogame or watch Violent Content.
Because with these themes in mind, That Trigger can always be at risk of happening.
