This question acts as a clarification to another question on this site. Here's the scenario:

  • You have 60' of movement at the start of your turn
  • You move 30' to any direction
  • You grapple someone at this point
  • How far do you have left to move?

  • \$\begingroup\$ The original question linked to in this question is already asking how multiple modifications to speed work. The comments debating the answer to that question, which have spilled over into this question, have all been removed now. Answers to that question should be used to address/settle that debate. \$\endgroup\$ – SevenSidedDie May 18 '16 at 19:32

No, grappling halves your speed attribute, it does not cost half your movement:

When you move, you can drag or carry the grappled creature with you, but your speed is halved, unless the creature is two or more sizes smaller than you.

The way to read movement-changing rules clearly is to always keep in mind that there are two separate values operating:

  1. Your speed value.
  2. Your amount of movement to spend in a round, which is derived from your current speed.

So in the scenario outlined, your speed starts at 60' and is halved to 30' by grappling, after you've already spent 30' of movement in the round. Since you have spent 30' of movement, equal to your 30' speed, you have zero movement left.


When you move, you can drag or carry the grappled creature with you, but your speed is halved, unless the creature is two or more sizes smaller than you.

Speed isn't distance.

speed = distance/time.

Your speed is halved. You moved 30' (of 60') at full speed. You can now move the rest of your movement at half speed or 15' more feet of movement.

Say you're driving down the freeway at 60mph. After half an hour you've traveled 30 miles. Then you halve your speed. You can still drive 15 more miles before the hour is up.

Compare the Wording in Grapple to Prone

Moreover if it would take half of your total movement, it would say so like it does for getting up from prone:

Standing up takes more effort; doing so costs an amount of movement equal to half your speed (emphasis mine)

Which is clearly half of your total speed. Grappling, however, says:

your speed is halved

The difference is noticeable and important. In context, it is clear it halves your speed not your total movement.

  • \$\begingroup\$ Based on the way Grapple is written, I believe it is. RAW isn't clear on the issue, and I see no tweets from the creators. Honestly, ruling either way isn't game breaking as long as it is applied consistently, and RAW could be read either way. I do think my answer is the intention. \$\endgroup\$ – J. A.

    \$\begingroup\$ The "Using different speeds" section SRD p91, does not work in this way. There is no pro-rata of distance by time, simply subtracting distance travelled so far from current speed. If you treat a change to speed (due to using grapple or any other effect) the same as "Using different speeds" section of the rules, then this answer is likely not correct. This is not explicitly spelled out in the grapple rules - but probably the closest written rule. \$\endgroup\$ – Neil Slater May 21 '16 at 8:30
