If a character is on the bank of a river and they want to reach into the water and grapple a creature in the water (assuming that they are within the size limit to be grappled) are there any special rulings for grappling or is it the standard grapple check?
According to the Grappling Rule as listed on Roll20
When you want to grab a creature or wrestle with it, you can use the Attack action to make a Special melee Attack, a grapple. If you’re able to make multiple attacks with the Attack action, this Attack replaces one of them. The target of your grapple must be no more than one size larger than you and must be within your reach. Using at least one free hand, you try to seize the target by making a grapple check instead of an Attack roll: a Strength (Athletics) check contested by the target’s Strength (Athletics) or Dexterity (Acrobatics) check (the target chooses the ability to use). If you succeed, you subject the target to the Grappled condition (see Conditions ). The condition specifies the things that end it, and you can release the target whenever you like (no action required).
But when you look at Under Water Combat on Roll20
When making a melee weapon Attack, a creature that doesn’t have a swimming speed (either natural or granted by magic) has disadvantage on the Attack roll unless the weapon is a Dagger, Javelin, Shortsword, spear, or Trident. A ranged weapon Attack automatically misses a target beyond the weapon’s normal range. Even against a target within normal range, the Attack roll has disadvantage unless the weapon is a crossbow, a net, or a weapon that is Thrown like a Javelin (including a spear, Trident, or dart).
It appears there is no clear ruling and that the standard grapple check applies. Is that correct?
