## Algorithm for summation with lowest maximum temporary sum

I’ve got this problem on my last exam, which I struggle to deal with.

Lets say we have array of N integers (it can be float too, but lets say integers for sake of simplicity. We need to sum those numbers, but we can only use operation of summing two adjacent numbers. Goal of algorithm is to sum this sequence, so maximum of sum from this operation will be lowest possible.

For example: Lets say we have array -2 5 -3. First we sum 5 and -3, so the temporary sum is 2, and our sequence changes to -2 2. Then we sum -2 and 2, so now our temporary sum is 0. As we see, maximum of temporary sums was 2, and we cant get any lower. (summing -2 and 5 would give us 3, which is higher that 2).

My goal on that exam was to find best complexity algorithm, and proof its correctness.

What i tried: First thought was to use greedy algorithm, so just sum those two numbers which give lowest temporary sum right now. Problem is, i cant neither prove it is valid way to solve it, or find any counterexample. So i write here, maybe someone finds it interesting. Thanks for your attention

## How long do the temporary HP gained from the Aberrant Dragonmark feat last?

The Aberrant Dragonmark feat states:

You learn that spell and can cast it through your mark. Once you cast it, you must finish a short or long rest before you can cast it again through the mark. Constitution is your spellcasting ability for these spells. When you cast the 1st-level spell through your mark, you can expend one of your Hit Dice and roll it. If you roll an even number, you gain a number of temporary hit points equal to the number rolled.

How long do those HP last?

## What spell, magic item, racial, or class ability will give you the most temporary HP?

I was wondering, using only the official hardcover books (no UA or 3rd party), what is temporary HP cap at lv 20?

class, playable race, feats, non-legendary magic items, and spells allowed. You can use an epic boon if you have a way in game to get one. (ie through a feat)

## Is there anything that can bypass temporary hit points?

I have found a wizard spell from The Book Of Lost Spells, called Soul Shield. In my opinion, it is super overpowered, but my DM has allowed it.

The spell says that a wizard can convert their "real" hit points into twice as many temporary hit points, so long as you always leave yourself on at least 1 "real" hit point.

I instantly saw how amazing this was, however it leaves me wondering if there was a poison, disease, monster ability or the like that bypasses the buffer provided by temporary hit points and removes my remaining "real" hit point.
I have looked for such an ability, yet found none.

Is there one?

My DM likes to take things from homebrews quite a lot, so long as they are balanced, and I have had a look through a number of different sources. As such, a homebrew compendium is an acceptable answer for this question, but please link the source.

The spell in question works as follows:

### Soul Shield

2nd Level abjuration

Components: VS
Casting Time: 1 action
Duration: 1 hour
Concentration: No

You siphon some of your life force into a shimmering shield of light around yourself. Sacrifice any number of your hit points (up to your current total -1) when you cast the spell, and you immediately gain twice as many temporary hit points. You must leave yourself at least 1 “real” hit point. While any of those temporary hit points remain, you get tactical advantage on Dexterity and Constitution saving throws. Remaining temporary hit points disappear when the spell ends. The spell ends immediately if all the temporary hit points are lost.

After a user logons to cognito, he receives access and ID tokens. the ID token contains sensitive info like phone number, email, etc..

From all standards – ID token should not be used to gain access to an API: https://auth0.com/docs/tokens?_ga=2.253547273.1898510496.1593591557-1741611737.1593591372

In the backend, to get a session credential (to work with AWS resources) – you typically do this:

``identity_id_response = boto3.client('cognito-identity').get_id(     IdentityPoolId=identity_pool_id,     Logins={         provider: id_token #ID token! not access token     } ) ``

Then:

``provider = f'cognito-idp.{region}.amazonaws.com/{user_pool_id}'  response = boto3.client('cognito-identity').get_credentials_for_identity(     IdentityId=identity_id_response,     Logins={         provider: id_token #access token again     }, ) ``

Then, you can use AccessKeyId, SecretKey, SessionToken etc..

This is problematic as what if you want to send the ID token to multiple services (via SNS, etc..) so you could perform processing on behalf of the user? you basically send a sensitive token that contains sensitive user data over the backend.

So – it requires an encryption before sending this token, which seems like an overhead.

Any thoughts?

## 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.
