Alternative assaults have their good distance on the earth of tabletop video games and D&D specifically. 3.5e/PF each had an exhaustive listing of actions which might or can’t set off an OA.

fifth version simplified issues loads. One single set off left:

You may make a possibility assault when a hostile creature which you can see strikes out of your attain.

It appears the builders contemplate this explicit set off as crucial one. To my information, many wargames makes use of the same rule. So what occurs if we take away it? Why do we’d like it, within the first place?

Is there a considerable downside 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, for example), so I need to know what modifications ought to I count on inside a fundamental 5e gameplay (no feats, no variant guidelines) if the DM introduces “no alternative assaults” home rule.

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