The Science Team

Casting of this spell requires the verbal incantation: "I'm with the science team!" to be spoken aloud. 

The Caster summons forth one of 3 ghastly spirits, remnants of unfortunate researchers that were desintegrated in the creation of this spell. The spirit attaches to himself or an ally of the Caster within range that he (the Caster) can see. It then grants an effect to its target for the duration of the spell or until the ally leaves the range of the spell.

The Apprentice: grants the target an additional bonus action each turn.
"What are you doing there? May I help you with that, sir? How do you like your potion of speed?" 

The morning person: grants the target additional 15 speed each round.
"Sup, sleepyhead. I was already here 2 hours ago. Yesterdays report is copied, planner's updated and I made some muffins before i got to work."

The Professor: grants the target advantage on INT - and WIS - skill checks and saving throws.
"Every second I do not have my eyes on these two I fear the laboratory might blow up around me"

At higher levels: if cast with a slot of 4th level or higher, an additional different spirit can be summoned, at 6th level or higher all 3 spirits can be summoned.

The Science Team can be cast as a ritual spell in combination with the spells "Ressurection" or "True Ressurection" which leads to them being permanently brought back to life, either reforming their original bodies or binding their souls to an available humanoid body or construct. The Science Team is thankful for being resurrected and if given a space for working as well as a fair wage will continue arcane and scientific research of the casters choice. (the members of the Science Team are all spellcasters, stat blocks and spells at the DM's discretion or improvisation.)
~This spell can still be cast on lower levels with the same benefits after completion of the ritual though it does not require material components anymore~
