Survival Event

The Survival Event was a type of Event in Final Fantasy Record Keeper. 
==Overview==
Players were given a single Dungeon in which to play, as well as a choice of difficulty levels to play it through. Once a difficulty level was chosen, the player had to work through the Dungeon's battles to collect Memory Prisms that, in turn, allowed the player to progress up a Rewards "ladder". All collections were cumulative, meaning that the player's Memory Prism collections simply added to the player's prior count.
== Structure ==
The player began battle with a group of enemies at the selected difficulty to determine the base amount of Prisms collected. Then, as the player progressed through each round of battle, the game randomly determined the next enemy and assigned a Memory Multiplier for each battle, meaning that the player's current Prism count would be multiplied by the factor stated as the Memory Multiplier. The player could retreat at any time before completion and keep his accumulated Prisms, but would have to start the Dungeon anew at the first battle. All battles were to be played sequentially, and there was no option to go back to a prior battle. Thus, completing the Dungeon afforded the player the best chance at collecting the most Prisms in one sitting. In addition, one-time Rewards were collected on each difficulty level, as with a regular Dungeon.
The number of battles and the Stamina required for each were determined by the difficulty level chosen. However, this amount was constant within the Dungeon for the selected difficulty.
