One of my PCs (a halfling) has recently taken to riding on the back of another one of my PCs (a dwarf). I allowed this, as I didn't think it had any problems and it allowed the group to go faster - the dwarf's STR is high enough to hold both the halfling and both their equipment at once.

However, the party has recently started approaching a high-combat area, or at least an area where I plan to have many ambushes. I'm thinking that a PC piggybacking another PC might be a bit different in combat - obviously only one can move, but what about the attack?

I'm particularly concerned with how initiative order would work, as intuitively I think they should attack at the same time. Are both characters capable of attacking, such with a rider on a tamed, battle-practiced mount, or can only one attack while the other clings on? Should they attack at different times, or at the same time?

The answer to your question depends on if you treat the dwarf as a mount. If you do, the mounted combat rules cover you.

P. 198 PHB:

While you're mounted, you have two options.You can either control the mount or allow it to act independently. Intelligent creatures, such as dragons, act independently. […] An independent mount retains its place in the initiative order. Bearing a rider puts no restrictions on the actions the mount can take, and it moves and acts as it wishes.

Since the dwarf is intelligent, he gets his own initiative order and acts independently, as he wishes on his own initiatve. The halfling will move around with him, instead of using his own movement, until he dismounts. He will get to otherwise act or attack on his own initiative. Both can attack independently on their respective turns, and suffer no disadvantage.

Normally, a dwarf would not be able to act as a mount, because:

A willing creature that is at least one size larger than you and that has an appropriate anatomy can serve as a mount, using the following rules.

While its up to the DM what "an appropriate anatomy" is, from the example mounts in the PHB it seems a bit of a stretch to allow a humanoid body plan for a mount that is just one category larger.

If you do not want to treat the dwarf as normal mount and want to impose additional restrictions such as disadvantage to the attacks, because they must hold up and cling on to each other, that is entirely up to you: homebrew rules, like allowing riding a creature that is not a mount, require hombrew solutions. For example you could declare this works like a normal intelligent mount, but with disadvantage to attacks — it's up to you.

PS. Note that even if the players are acting at different initiative, the are still all acting "at the same time", because initiative is just an artifact for the players. In game, everyone is acting during the same six-second round simultaneously. (Thanks, @Jack)

    \$\begingroup\$ +1. Since the OP being concerned about the halfling and the dwarf attacking "at the same time", you might consider mentioning that attacking on separate turns is still "simultaneous". \$\endgroup\$

  • \$\begingroup\$ Well even if the attacks are considered to happen at the same time from a narrative standpoint, wouldn't this still pose problems mechanically? Specifically, if the halfling wanted to attack in melee, he would possibly have to technically/mechanically use his prepared action and reaction (for when the dwarf moves into close range on the dwarf's turn), not the normal attack action on his own turn, which could me for example no extra attacks. Obviously, perhaps a melee fighter would not choose to piggy-back in this way, but since this seems to be the OP's concern, the answer should address this. \$\endgroup\$

  • \$\begingroup\$ @J.E Yes I think that is where their question comes from more than the narrative perspective. If you use the rules for mounts and the rider wants to attack, as he doesn't control the mount's movement he either would need to ready an action for when he comes into reach, or accept that he only can attack what is in reach when his turn comes up (or needs to dismount and move how far he still can, to attack, but then is no longer mounted.) \$\endgroup\$ Apr 15 at 11:46
