Choosable Shroud mod allows you to choose the bonus of Shroud, and it will never fail. That will save your time if you are tired of saving&loading again and again just for an expected bonus...

Choosable bonus:
Get a buff on happiness/upkeep/research/shields/weapons/firing rate/ethic attractiveness/influence/unity/evasion/repair/lifespans/ship speed/army morale/sensor range
Summon a powerful avatar ship/army
Steal a technology from a fallen empire
Learn a rare technology
Promote a Chosen one
Form a covenant with an unspeakable being
CHEAT: You can have multiple avatars (only one in vanilla game), steal technologies many times, promote multiple Chosen ones (oh so-called "one"?) and even form multiple covenants!

Incompatible: Any other mods which modify the Shroud.
