That question was recently asked and has comments and various votes about whether it should be open or closed. Is it on-topic? To quote the current form of the question in full:
The PHB specifies that there are two parts in a spell description, the block of information and the spell's effect:
Each spell description in chapter 11 begins with a block of information, including the spell’s name, level, school of magic, casting time, range, components, and duration. The rest of a spell entry describes the spell’s effect.
The block of information contains the seven headings listed above.
D&D Beyond spell blocks of information retain the seven PHB headings but add two more; attack / save and damage / effect.
Roll20 Compendium blocks of information retain the seven PHB headings but add two more; target and classes.
In the PHB, a spell's target may be listed in the spell's effect, but then again it may not, which can lead to questions about what the target of a spell actually is. For many spells it simply is not clear what the target is.
Thus, the explicit listing of the target in the Compendium entries could be a valuable source of clarifying information, if they were official, which I doubt.
What was the process of selecting the target of a spell for the Compendium write-up?
Was it confined entirely to the Roll20 team, in which case the target listed there is clearly not RAW?
Did the WotC Design team offer guidance and suggestion as to the target listings, in which case a listed target might have the status of RAI?
The actual questions asked are those last three. Are they on-topic for this site?
