In a game I DM'd, a PC had cast a spell with a Concentration requirement and was subsequently Paralyzed. I quickly checked the description of the Paralyzed condition, which said nothing about Concentration but did say that the character was Incapacitated. I checked Incapacitated, which also says nothing about Concentration. I thus ruled in-game that the PC could maintain concentration on the spell even while Paralyzed.

However, post-game, I read the description of Concentration, where it clearly says that you lose Concentration when you are Incapacitated. It seems (in my opinion) like that is an important enough consequence of the Incapacitated condition that it should be listed with the description of the condition.

So now I wonder - are there other mechanical consequences of Incapacitated that are not listed in the description of the Condition itself, but are found somewhere else?

Note: An earlier version of this requested information on any Conditions. I have edited this to just Incapacitated to narrow the scope.

Note: One of the Consequences of Incapacitated is that a character cannot take actions or reactions. Abilities that require the use of actions or reactions are therefore already assumed to be prohibited and do not need to be listed as part of an answer. Maintaining Concentration does not normally require spending an action or reaction.

Note: Early comments indicated that a comprehensive list would be very large. I am principally interested in consequences that I should track as a DM. I would consider class- and race-based abilities primary the responsibility of the player. For example, the player of a Barbarian who wants to use Danger Sense should know how Danger Sense works, but as a DM, I will have numerous NPC's with Concentration effects so that is something I should know.

Maintaining Concentration does not normally require spending an action or reaction.

What the question is also not: I am principally interested in consequences that I should track as a DM and that, as with Concentration, would not be immediately obvious. I would consider class-, feat-, and race-based abilities primary the responsibility of the player. For example, the player of a Barbarian who wants to use Danger Sense should know how Danger Sense works, but as a DM, I will have numerous NPC's with Concentration effects so that is something I should know. Likewise, a monster with a special effect ended by Incapacitation would not need that listed here if it was included in its stat block, but if the stat block just referenced a general ability that would then need to be looked up as well, that would be a good candidate for the list.
