## Is there any power that allows one to drain PP?

I’m currently reading through the rules and wondering: Is there any power that allows one to absorb/drain PP of others?

For example in some other games like wod and part time gods some splats have the ability to devour one anothers soul and thus increase in power, and I’m wondering there if such a power is stated also in M&M

## Does psion and argent power points and powers stack?

Description of psion says:

Every psion must decide at 1st level which psionic discipline he will specialize in. Choosing a discipline provides a psion with access to the class skills associated with that discipline (see above), as well as the powers restricted to that discipline. However, choosing a discipline also means that the psion cannot learn powers that are restricted to other disciplines. He can’t even use such powers by employing psionic items. (See Psionic Disciplines, below, for a brief description of each discipline. Chapter 5 of this book contains a list of powers available to all psions and lists of powers restricted to certain disciplines.)

if character is psion 1/argent 1 for example, may he use the dimension hop and another argent powers, or this power is now forbidden?

And also – does power point stacks? Is it like – 2 pp from argent 1st-lvel/2 pp from psion 1-st lvl, and also bonuses from wis\int?

dnd books: expanded psionic, complete psionic

## D&D 5E: Open world gaming with vast power differences?

I would like to run a game with an open world, where the party can explore unconstrained. I would like to do it in D&D 5E, but the power differences are very stark between levels. How can I make the world realistic, without scaling everything up as the players advance their levels (so, first only goblins everywhere, then suddenly orcs, etc.). On the other hand, I don’t want a TPK every other session, just because the players misjudged the danger.

I am familiar with making open world campaigns in other games, where the differences in power level are less stark (and you can decrease the power gap by smart, tailored tactics and planning), but I am vexed as to achieve this in level-heavy game as D&D.

## How does the Insidious Extra interact with the Weaken Power?

I’ve been playing around with the Weaken Power and trying to find its best application. As of right now, I think it’s in Weaken Senses. Almost every enhancement in Senses requires 1 rank at 1 point per rank and an unaugmented human has 11 or 12 ranks in senses (Acute, Accurate, Ranged vision/Acute, Radius, Ranged auditory/Radius olfactory/Accurate, Radius tactile/Close mental); with all this in mind, there would be virtually no situation where this wouldn’t be useful. However, I’ve also been experimenting with placing extras on Weaken; the one that caught my attention was Insidious, which prevents targets from understanding what exactly happened to them. My concern with this is whether or not this application of Weaken automatically violates Insidious‘s “feels fine until some deficiency makes it apparent that they are weaker” condition.

As such, Can Weaken Senses benefit from the Insidious Extra? If not, what do I need to do to have it benefit from Insidious?

## Functionally, how does Power Word Kill work?

I was just reading this answer, which introduced me to the Power Word Kill spell:

You utter a word of power that can compel one creature you can see within range to die instantly. If the creature you choose has 100 hit points or fewer, it dies. Otherwise, the spell has no effect (101 hp or more).

Functionally, how does this spell work? If I’m understanding this correctly, a PC can speak a word, and if the target has less than 100hp, they instantly are killed without the chance to save. My reason for asking is that this seems extremely overpowered, to the point where it could be used to kill deities or high-level bosses with little effort (especially those who rely less on having high HP and more on dealing extremely high points of damage – Moon Druids come to mind here).

While I recognize that the DnD system does allow for extremely powerful spells (cough cough wish cough cough), this one in particular seems to stand out.

Thus, functionally, how does Power Word: Kill actually work?

Note: I am not asking whether or not the community subjectively finds this spell overpowered. Rather, I am attempting to confirm how this spell works in practice, in order to decide for myself if it is overpowered.

• Are any saves permitted?
• Does the spell need to be heard by the target, or seen being cast?
• How might resistances or type-immunity play a role (if any)?

The purpose of this question is to confirm that this spell works in the way I am imagining, which while to me seems overpowered, if I am incorrect may not be the case.

## What other spells can power the Locate City Bomb?

The locate city bomb is a series of metamagic feats you can apply to a the locate city spell to do high damage over a very wide area.

Typical process:

1. Cast locate city from Races of Destiny.

2. Use the Snowcasting feat from Frostburn to add the Cold descriptor to locate city.

3. Use the Flash Frost feat from Player’s Handbook II, which can only be applied to cold spells, to add 2 cold damage to all creatures within the area of the Snowcasted locate city.

4. Use the Energy Substitution feat from Deities & Demigods, which can only be applied to a spell that deals acid, cold, electricity, fire, or sonic damage, to turn the cold damage to electricity (or sonic) damage.

5. Use the Born of the Three Thunders feat from Complete Arcane, which can only be applied to an electricity or sonic spell. Among other things, this forces creatures within locate city’s area to make a Reflex save.

6. Use the Explosive Spell feat from Complete Arcane, which can only be applied to a cone-, cylinder-, line-, or burst-area spell that allows a Reflex save, to force those within who fail the Reflex save to the edge of the effect, taking 1d6 damage for every 10 feet moved.

If the locate city spell were banned, what other spells could use this combination of feats to produce a similar effect?

The locate city spell has a radius of 10 miles/level; I’d consider a spell to have a similar effect if its area of effect was also very large (and if the rest of the locate city feat stack worked with it).

## Power towers Power towers from x to n

Power towers How can I make mathematics calculate a power tower for a succession of numbers, bone instead of writing them, mahematica does the iterative calculation.

     cal= 99^2^3^-----1000   

How to make mathematics write it and if you can calculate it?

I understand that there may be an overflow of memory upon actual calculation, it can also help me

## Is the power of a natural number logspace-computable?

Given $$n\in\mathbb{N}_+$$, is the simple power function $$\mathrm{\lambda}\,x\in\mathbb{N}_+.\,x^n$$ logspace computable by a logspace transducer (which has a read-only input tape, a working read-write tape of size $$\mathcal{O}(\lambda x.\,\log x)$$, and a write-only output tape), assuming that the input and the output are in binary? (It is not even clear to me how to do it for $$n=2$$ in logspace.) Any ideas or references?

## How to calculate the power spectrum and cross spectrum for two dimensional data?

I have two sets of data:

G={{G_1,x_1,y_1},{{G_2,x_2,y_2}},…..,{G_{n},x_n,y_n}}

H={{H_1,x_1,y_1},{{H_2,x_2,y_2}},…..,{H_{n},x_n,y_n}}

where H_{n} and G_{n} are values of G and H in the point (x_{n},y_{n}). I want to calculate the power spectrum and the cross spectrum . Can you help me ? Thanks.
