Do multiple sources of temporary hit points combine, or do you only get one set?

Do multiple sources of temporary hit points combine, or do you only get one set?

For example, say you cast armor of Agathys and false life on yourself. Do you have two separate pools of temporary hit points, or do you have to pick one of the two? By separate pools, I mean that you have 5 temp HP from AoA and 8 temp HP from FL. If you take 10 damage, can you pick one of the two pools of temp HP and take the leftover damage to your real HP, but still have the other pool to protect against a second attack?

I ask because a warlock player in my game insists that she gets both pools, but I think it should be either-or.

How do multiple sources of temp HP interact with one another?

A question regarding the stacking of temporary HP

Right now I am playing a Mystic (UA), and I have chosen the Order of the Immortal as my discipline. One of the abilities I have acquired gives me 5 temporary hit points at the start of my turn, as my intelligence is a 20.

If I have gained temporary HP in one turn and I haven’t been hit, do I continue gaining the HP or do I have to expend the Temporary HP before gaining more?

Strategies for effectively running a temporary online game

Other questions have done a good job of outlining where to find online players and some of the tools available for ongoing virtual games (Roll20, Fantasy Grounds, etc). Many of those tools have a cost associated with them and a large time commitment to configure a custom, homebrew game.

Occasionally, circumstances prevent us from gathering in the way we prefer. The 2020 COVID-19 pandemic is a good example. During those times, finding ways to continue to play together, even if in a non-standard, non-permanent way, is important.

In this question, I’m interested to know what DMs and their players are using to temporarily convert their normal pen and paper, in person gatherings into a system that works with a remote group. I’m specifically interested in answers that address the following common concerns with this type of conversion:

  1. Cost – Low or no added cost (it’s temporary)
  2. Roleplaying – Support for high quality, low delay audio
  3. Content – Support for custom content including maps, handouts, items, etc
  4. Combat – Support for combat positioning, distances, and area effects normally done on a battle mat

Can you usemore than 1 PP ti increase Temporary HP Aegis Toughened Suit feat?

Can you use more than 1 PP ti increase Temporary HP Aegis Toughened Suit feat?

Build the ultimate damage sponge with a good enough Damage Resistance and THP. I have Aegis Lv 5 with 16 Int and 14 PP (total with high Int mod). I plan on using at least my Lv’s worth of PP to try to get 25 THP and DR of 4/-.

Wait are Aegis still limited in spending PP equal to their Lv? I think this question is pertinent here.

If an artillerist-artificer has 2 protectors, does the temporary hp given by the protectors stack?

This is a somewhat loaded question that I could have stated more neutrally, but I didn’t.

Premise: the artillerist has a choice of ‘cannons’ to use. One of those choices is the protector which does the following:

The cannon emits a burst of positive energy that grants itself and each creature of your choice within 10 feet of it a number of temporary hit points equal to 1d8 + your Intelligence modifier (minimum of +1).

At level 15 this artificer gets to use two cannons. The feature reads:

You can now have two cannons at the same time. You can create two with the same action (but not the same spell slot), and you can activate both of them with the same bonus action. You determine whether the cannons are identical to each other or different.

So you can have two protectors out which activate at the same time, but does their activation count as one iteration of an effect or ability, or two? This is important because temporary hp can’t be added together. If the cannons are adding two separate pools of temporary hp they can’t be added together, so are the cannons effects considered together or separate?


Does the temporary hp from the protectors stack or not?

Using Fiendish Vigor after losing temporary hit points

A D&D 5e warlock takes the Fiendish Vigor invocation.

Lets say the warlock gains 8 temp hp from Fiendish Vigor. Within the next hour takes 8 damage. Then the warlock uses Fiendish Vigor for 5 temp hp.

What happens now:
A. The warlock gains 5 temp hp and can repeatedly gain temp hp during an encounter whenever damage has removed the current temp hp.
B. The 5 temp hp replaces the previous 8 temp hp and the warlock loses 3 actual hp.

For reference:

Fiendish Vigor:
You can cast False Life on yourself at will as a 1st-level spell, without expending a spell slot or material components.

False Life:
Duration: 1 hour.
Bolstering yourself with a necromantic facsimile of life, you gain 1d4 + 4 temporary hit points for the duration.

Consequences of Relying on temporary hit points instead of armor for a homebrew class?

I am creating a homebrew tanking class for DND 5e, and I want to add some flavor rather than going with same formula as fighter, barbarian, and paladin.

I am thinking that instead of armor the class could rely on a reserve of temporary hit points to absorb damage. This reservoir of temporary hit points would be equal to half the hp maximum and would replenish fully every long rest, or when you regain hit points as part of a short rest, potion, or spell, you would regain half as many temporary hp.

What would the mechanical implications of such a class, and how would I prevent them from boosting their AC to make this combo OP?

define temporary variable inside the the definition of a funciton

This is mostly a matter of me trying to define functions in a tidy way. Suppose I want to define a function which is very complicated and so would like to break it into pieces. To get the idea, here’s a simple example

instead of this

f[x_,y_]:= (x^2 + y^2)/(x y)  

I want to write it along the lines of

f[x_,y_]:= A/(x y) where A= (x^2 + y^2) 

What is the correct way to do this?
