A magician goes around a corner to find two kobolds brandishing their weapons. Roll initiative!
The DM determines that neither side is surprised. The DM makes a single initiative role (10) for the two kobolds, since they are identical creatures (PHB, page 189). The magician has a great roll (15) and goes first.
The assistant decides that it is better to be sure than regret and reverse hold person to 3rd level, pointing to both kobolds. One kobold fails to save and is paralyzed, but the other (miraculously) succeeds. The magician now feels confident in his success and closes within 5 feet of both kobolds.
It's time for the kobolds to act. Kobolds has the Pack Tactics feature, which gives them advantage in attack rolls against a creature if a non-disabled ally is within 5 feet of that creature. One of the kobolds is paralyzed, which means he is also incapacitated. Hold person grants additional salvation at the end of the affected kobold turns.
Each kobold should have its own turn, but one full turn before the other, possibly allowing the paralyzed kobold to save vs. hold person? In short, is there any way for the non-paralyzed kobold to take advantage of Pack Tactics in this initiative if we count this round?
