[RPG] Is it mathematically possible to only have 3/4th cover

battle-mapcoverdnd-5e

In Is the DMG 3/4 cover diagram incorrect? the question asker points out the diagram shown in the DMG implies 3/4th cover, but it's possible to get a better angle on the defender meaning they only have 1/2 cover.

To determine whether a target has cover against an attack or other effect on a grid, choose a corner of the attacker's space… trace imaginary lines from that corner to every corner of any one square the target occupies. If one or two of those lines are blocked by an obstacle (including another creature), the target has half cover…

Diagram showing various approaches to getting cover, from the DMG pages 250 and 251

Is it mathematically possible to construct a scenario where only 3/4th cover is possible? Intuitively I can't think of a place to put the attacker in the diagram where one corner isn't able to get 1/2 cover by picking a better square, whilst still having some attack on the defender.

Best Answer

Yes.

This does it:

Choosing any other corner gives full cover.
