Dynamic Reactions
Reactions cost 1 Effort and are performed when it is not your turn. You can perform each reaction no more than once per round, and you will start your turn with fewer actions. The reactions are:
Defend
Reduce damage from any single attack by your Armor Class modifier. At the DM’s discretion, some damage may not be avoidable (e.g., psychic damage, or some areas of effect). This reaction replaces the Dodge action.
AC Modifier: your AC - 8
Interpose
If an ally within 10 ft. would be struck with an attack, you can push them out of the way and become the new target of the attack. You enter their square and move them to an adjacent square of your choice.
Yes! As long as you have enough actions to spend, you can Interpose and Defend at the same time. However, you won’t be able to do either reaction again until your next turn is over since each of those is limited to 1/round.
Opportunity Attack
A melee attack made with Disadvantage against an adjacent enemy as it willingly moves away. Enemies do not make Opportunity Attacks—only you can.
Help
Grant an ally Advantage on an attack, skill check, or saving throw if you can reasonably explain to the DM how you could help in a given situation. The DM may call for a skill check or grant Advantage automatically, depending on how good the idea is.
Assess
Choose one of the following and then make a DC 12 skill check to:
- Ask a Question. About a weakness, ability, or immediate plans of enemies, the environment, story, etc. The DM will answer honestly.
- Create an Opening. Increase the next Primary Die Roll against a target by 1 this round.
- Anticipate Danger. Reduce all Primary Dice rolled against you by 1 this round.
Which Skill To Use? Whatever skill you use must make sense based on the circumstances. For example, if you’re close to an enemy, you could use Athletics to create an opening, but against an enemy that is far away, that may not make sense. Or if you want to ask a question about the weaknesses of an elemental, you’d likely use Arcana.
Monsters Are Smart! You cannot assess using the same skill more than once in a single encounter, as your foes adapt to your tactics. You’ll need to stay creative!
