Trivia
The mod has a custom Game Time called "4th Day." Which has been confirmed by Link himself that using this Game Time and following the events of it is a complete reference to the "BEN Drowned" creepypasta.
The main feature of Fierce Deity Link Mod V2 is being able to transform Titan Eren into different types of "mask" transformations. This is a direct reference to the four masks you obtain and are able to use in The Legend of Zelda: Majora's Mask.
After some time, Link has openly admitted that the mask transformation sequences are an altered version of the Berserk sequence for Titan Eren from BRS Mod v3 and v4. He has credited BRS himself and the mod accordingly for it in the "Credits" section.
