Back when I first picked up a sword, I thought every turn in combat was just “swing and pray.” Then came the kobold ambush, the flying basilisk, and the enchanted outhouse incident of Redwater—and I learned real fast that knowing the difference between actions, bonus actions, and reactions in D&D 5e can be the difference between hero and headstone.
So if you’re new to the adventuring life—or just keep forgetting what you can actually do in six seconds—pull up a chair. I’ll teach you what they mean, how they work, and how to survive long enough to brag about it.
What Is an Action?
The action is the big thing you do on your turn. The meat of the move. The swing of the axe. The casting of a spell. The time you try to wrestle a minotaur while screaming your mother’s maiden name. You get one per turn, and it should count.
Common Actions:
- Attack: Hit something (or someone).
- Cast a Spell: Like Cure Wounds or Fireball (if it takes 1 action to cast).
- Dash: Move again, as far as your legs allow.
- Disengage: Slip away without getting clobbered.
- Dodge: Make yourself hard to hit (great for meat shields).
- Help: Give an ally advantage.
- Hide: Duck behind cover.
- Ready: Prep an action for later.
- Search / Use an Object: Look around or interact with the environment.
Example from Dave:
“I once used my action to wrestle a cursed treasure chest that had sprouted legs. Rolled a nat 20. Rode it like a war boar for two rounds before it exploded. Still worth it.”
What Is a Bonus Action?
A bonus action is a quick move—like a flick of the wrist, a shouted spell, or a trained instinct. You only get one if something gives you one, like a class feature or certain spells.
Common Bonus Action Sources:
- Rogues: Cunning Action (Dash, Disengage, or Hide)
- Two-weapon fighting: Make a second attack with your off-hand
- Spells: Misty Step, Healing Word, Spiritual Weapon
- Class Features: Barbarians’ Rage, Monks’ Martial Arts, Bards’ Bardic Inspiration
Example from Dave:
“In the Battle of Spitecliff, I used my action to throw a barrel of lamp oil, then my bonus action to rage so I could leap through the fire it caused without flinching. Don’t ask about my eyebrows.”
What Is a Reaction?
A reaction is something you do outside your turn, in response to a specific event. You only get one per round, and it resets at the start of your next turn.
Common Reactions:
- Opportunity Attack: When a creature leaves your reach.
- Shield (spell): Adds +5 AC when you’re about to get hit.
- Counterspell: Stop someone else’s spell in its tracks.
- Ready Action: If you used your action to prepare a reaction.
Example from Dave:
“I once set up a Ready action to tackle a wereboar off a cliff the moment he tried to escape. Reaction triggered, we both went over. He died. I survived by landing in a cart of cabbage. Smelled like stew for a week.”
Can I Use All Three on the Same Turn?
YES. If the stars align, you can:
- Use 1 action
- Use 1 bonus action (if granted)
- Use 1 reaction (if triggered)
Example from Dave:
“I once used my action to hit a hobgoblin, my bonus action to chug a flask of firebreath, and my reaction to burp-flame into a charging bugbear’s face.
Was it smart? No.
Was it glorious? Absolutely.”
Quick Breakdown Table
| Type | Timing | How You Get It | Examples |
|---|---|---|---|
| Action | On your turn | Always available | Attack, Spell, Dash, Dodge |
| Bonus Action | On your turn | Class/Spell/Feature-based | Off-hand attack, Rage, Healing Word |
| Reaction | On other turns | Trigger required | Opportunity attack, Shield |
Final Thoughts from Dave
Knowing the difference between actions, bonus actions, and reactions in D&D 5e isn’t just about following rules—it’s about playing smart, surviving longer, and looking twice as heroic doing it.
So next time you enter combat, ask yourself:
- What’s my main move?
- What else can I do?
- And what surprise do I have waiting for anyone foolish enough to make the first move?
Play like every second counts—because in D&D, it often does.
