Blend two inputs into one using the extremely handy Summing Amp from JHS Pedals.
In some instances, one of your pedals might disrupt another in a way you want to avoid. For example, if you don't want your compression pedal squeezing the life out your fuzz, the Summing Amp can solve this by running each in parallel.
Using two delay pedals at the same time in the same effects signal can cause one to delay the other. The Summing Amp will organise these to produce the clarity you imagined.
Those of you who love to experiment with signal chains and effect combinations will find the Summing Amp to be an important tool in your creative arsenal.
