If you get a 5th copy as a drop from farming Lava Tube (or one of the few other places where it drops), MLB it immediately.

If you don't have 5 by the end of the event, then consider the following:

If you like the effect and want to use it in the future, keep them separate and level them to 20 using garbage CEs from the FP Gacha, so that multiple servants can use it.

If you only want to keep it as part of your collection and don't plan on using it, combine them AFTER the event, in order to save space.
