Alternative assaults have their great distance on the planet of tabletop video games and D&D specifically. 3.5e/PF each had an exhaustive checklist of actions which may or cannot set off an OA.

fifth version simplified issues quite a bit. One single set off left:

You can also make a possibility assault when a hostile creature that you would be able to see strikes out of your attain.

It appears the builders take into account this explicit set off as an important one. To my information, many wargames makes use of the same rule. So what occurs if we take away it?

Is there a considerable drawback with turn-based gameplay, which OAs resolve?

The rationale I ask is as a result of there are 5e-based video games which doesn’t have OAs in any respect (5 Torches Deep, as an example), so I need to know what adjustments ought to I anticipate inside a fundamental 5e gameplay (no feats, no variant guidelines) if the DM introduces “no alternative assaults” home rule.

I am extra enthusiastic about base mechanics, somewhat than explicit OA-dependent 5e spells or options (like Rogue’s Crafty Motion turns into much less helpful, and so on.)
