D&D 5E Rules Question: PC Auras

[Reynard]

One of my players is playing a spore druid that can create an aura of spore nastiness. The ability says that he can use his reaction to cause damage to a target that starts its turn within the aura or moves into it. Last night he was moving so that the enemy was in the region, using his reaction to force the damage, and then moving away again.

Is that legal? Is there an explicit rule? A sage advice?

Thanks.

IMO no (but I am not very familiar with the feature), the target is not moving into it, the PC is bringing the aura into them.

For the record, the ability isn't that big of a deal and really not a very good trade for a reaction, but I don't want to set a precedent for other, more powerful aura like abilities.

Moving the aura over something is not the same as moving into the aura.

The idea is that if they start their turn they can take damage. Then, if they stated outside of it and moved in? Also take damage.

It sounds like he’s taking a reaction in the middle of his own turn, which doesn’t work. You can only take reactions on turns other than your own.

I'm having trouble picturing how this would work. The way I read the ability the way it would work is:

Player's Turn - moves so that the enemy is within their aura
Enemy's Turn - it starts its turn in the aura, so the player uses a reaction to damage the enemy
Player's Turn - moves away from the enemy so its outside of their aura

Is that what's happening? Or does the player think that moving the aura over the enemy counts as the enemy moving into the aura? Because my understanding of the rules is that when they say "moves into the aura" they mean the target is actively moving into it and the ability is reacting to that movement.

This.

This is not true per the SRD:

Reactions​

Certain special abilities, spells, and situations allow you to take a special action called a reaction. A reaction is an instant response to a trigger of some kind, which can occur on your turn or on someone else’s. The opportunity attack is the most common type of reaction.

When you take a reaction, you can’t take another one until the start of your next turn. If the reaction interrupts another creature’s turn, that creature can continue its turn right after the reaction.

You can only take reactions on turns other than your own.

Not true, although usually that is the case.

Example: I cast a spell.
Enemy counterspells.
I counterspell their counterspell.

No, that is not "legal" if you quoted the aura correctly. The target must start its turn or move into the aura to be damaged. This does not include the player moving into range of the target.
