Yesterday, our group was fighting a boss, and I had successfully thrown a net to restrain him (a condition which he could end by either using an Action to make a DC 10 Strength check, or by doing 5 slashing damage to the net by attacking it at disadvantage).
On a subsequent turn, as the boss was still netted, I decided to throw another net (which hit him too), with the objective to force him to use two Actions (or two successful attacks) to free itself.
The DM accepted the "stacking nets" effect, but I'm wondering if it was legitimate, considering that same-name game effects cannot stack at the same place and time, or something like that.
My question is : can you apply multiple net effects to a single target, thus forcing it to spend multiple actions (or attacks) to free itself from the restrained condition ?
An argument in favor of a "yes" would be to say that the different nets cover different parts of the target's body. An argument for a "no" would be to say that a net, by default, covers the entire body, and therefore, the anti-same-name-effect-stacking rule would apply there.
