Each round represents approximately 6 seconds in the game world. A round presents an opportunity for each character involved in a combat to take an action.
Each round’s activity begins with the character with the highest initiative result and then proceeds, in order, from there. Each round of a combat uses the same initiative order. When a character’s turn comes up in the initiative sequence, that character performs his entire round’s worth of actions.
For almost all purposes, there is no relevance to the end of a round or the beginning of a round. A round can be a segment of game time starting with the first character to act and ending with the last, but it usually means a span of time from one round to the same initiative count in the next round. Effects that last a certain number of rounds end just before the same initiative count that they began on.
