However, from a simulation standpoint, it made sense. There are times when you might want to wait for an allay to act (such as casting a spell) before rushing into combat. Currently, only the Ready Action allows that kind of delay, but you are then limited to an attack or movement only, but not both. I wanted a way to delay an action but still prevent the potential abuse present in prior editions.
When you Delay, you may not move or attack or take a bonus action in this round as you hesitating to assess the situation before acting. You may take an opportunity reaction if circumstances allow. When you Delay, you re-roll your initiative check and your PC will be able to act in the following round at the new initiative count. The result may move your action higher or lower in the initiative order in the next round, but you may not act in this round other than reactions.
1) PCs may use their Intelligence or Insight (Wis) bonus instead of their Dexterity bonus for the new initiative check.
2a) PCs may re-roll initiative with Advantage to make it more likely they will get to act early in the following round.
2b) or PCs automatically go to the top of the initiative count (no re-roll) of the next round. If more than one PC delays, they roll to see who gets to go first. (Thanks +Mark Van Vlack)
With the chaos of combat, any hesitation may be a a few seconds or many seconds as the PC assesses the situation and decides when to act. The new initiative roll models this uncertainty and remove the potential for abuse at the same time. With the optional mechanic, a DM could give the PC a better chance to act on a higher count in the following round, but it still prevents the "gang up on an enemy" meta-abuse because the initiative order is still semi-random.
What do you think?
