D&D 5E [House Rule] Swap an action for a bonus action

[Horwath]

I am confused if - you trade your action for a bonus action, you already have two bonus actions? What is the difference between those two options you describe?

I think its not a problematic change from a balance perspective, although they might be some cheese/exploit I am not aware of when having two bonus actions. But in general an action is more worth than a bonus action, so it should be ok. I agree that it will slow down the game even more though.

I was meaning, your trade your Action for 2 Bonus actions, then you still have normal Move and normal Bonus action.

trading your Action for Bonus action is a non question, I do not know why is it not in core rules?

better question would be;
Can you trade your Action to perform TWO Bonus actions?

Now that is something to think about.

what is the value of Action?
what is the value of Bonus action?

or can you trade your whole Move for extra Bonus action.

or can you trade your whole Move and Bonus action to perform another Action.


off-topic, maybe whole round should be 6 action points(for 6 seconds):

Action: 3pts
Move: 2pts
Bonus action: 1pt

That is way off.

A monk could do 3 unarmed strikes on top of their action at level 1.

At level 3 they can flurry and attack 6 times on top of their action. Which they could use for 3 more bonus action attacks.

At 6, they can flurry 6 times for 12 attacks.

At level 10 they can attack 18 times only using bonus actions.

Yes, their ki is running out fast. But 18 monk unarmed strikes, potentially against a prone foe (open hand technique) is about 150 damage on average...

Edit: the way 5e works, bonus actions are too wildly different in value to give them a comparable cost in move or standard action fractions.

Swapping an action for a bonus action that you did not already have used might be the only sane way to make it work well enough. And even then, a monk might gladly trade a single attack at level 1 to 4 for a flurry of blows (Assuming they used their other bonus action for something like ki enhanced step of the wind).

Ah so 3 bonus actions in sum? Without testing it that feels like too much to me but I might get convinced.

Bonus action in the round without Action is usually meh,
Sure, monk could burn lots of Ki for unarmed strikes, but that is it.
You are limited with spellcasting rules,
rogue could do 4X move and do absolutely nothing else.

barbarian/druid shifter could rage and change forms and still do nothing towards opponents.

you could drink 3 potions? very few situations where that would be game changing.

it's just spitballing,

sure, Bonus action can be 2 pts and move can be 1pt.

but if you turn a turn into 6 pieces, then you can play around with cost.

I.E.

move is 2 pts, but Hide is 3pts with move, or disengage is 3pts move also.
Run in a straight line on normal terrain can be 3pts for 2x movement.

spellcasting can go from 1pt to 6pt cast, still limited to one spell slot used per round.
quicken spell can reduce casting cost for 1pt,
subtle spell can increase for 1,2 or 3pts, depending on how many components you remove without a sorcery cost.

attack can be 3 pts, then 2pts, then 3pts for 2 attacks, then 1pt, then 3 attacks for 2 pts and then 2 attacks for 1pt.
