Maintaining Miss Chance at High Levels (Or Similar Defenses)

From my time spent reading answers here, it seems relatively commonly accepted that in Pathfinder, AC is a weak defense. One claim I’ve seen put forth is that it’s entirely possible to obtain a miss chance that equals or exceeds the protection granted by any level of AC; I find this believable given spells like mirror image, blur, and displacement. I’m currently playing a Pathfinder campaign that’s just hit 14th level where I’ve been making decently heavy use of miss chances in place of AC1, and I’ve personally noticed that some form of sense capable of negating most miss chances (generally blindsight or true seeing) is increasingly common.

What ways are there in Pathfinder for a character to make effective use of miss chances at high levels in the presence of supernatural or magical senses that bypass conventional sources of miss chance? Options for any character are acceptable, though given Pathfinder’s large number of two-thirds casters, I’d especially like to see answers not limited to full casters.

I’m also entirely open to a frame challenge of the form that "miss chance is simply not effective at higher levels in Pathfinder," in which case an answer that elaborates on alternative defenses at high level would be preferred.

1 In case anyone’s curious, I’m playing a silksworn occultist in a War for the Crown campaign. We are using basically all first-party sources as well as Path of War from Dreamscarred Press. The specific issues I’ve been observing are a combination of enemies bypassing miss chances and mirror image as well as either enclosed spaces or highly mobile and proactive dangerous melee enemies.

Does Ocular spell make every eligible damage spells have a critical chance since it becomes a ranged touch attack (ray)?

Ocular spell states:

(…)When you release an ocular spell, its effect changes to a ray with a range of up to 60 feet. If the spell previously would have affected multiple creatures, it now affects only the creature struck by the ray. You must succeed on a ranged touch attack to strike your target with an ocular spell, and the target is still permitted any saving throw allowed by the spell.(…)

Every spell that has a touch attack (melee/range) Do have a critical hit chance (20X2)

So If I was to release an Ocular Fireball (only affects 1 creature now and it still gets the Reflex Half saving throw though). It could indeed be a critical hit.



I know fireball might not be the best spell for this combination, it was just for the sake of the question.

Is there a reasonable chance of a well-funded agent obtaining raw traffic over Tor circuits

If an agent has a few middle Tor relays (Am) and a few exit Tor relays (Ae), could they obtain the original traffic of some of the circuits with a reasonable probability?

Let’s assume, without too much loss of generality, that Tor only uses middle-middle-exit circuits and that there are M middle relays and E exit relays.

The probability of such a circuit consisting only of nodes this agent controls then is:

P = Am/M * (Am - 1)/(M - 1) * Ae/E 

According to Tor Metrics, there are just short of 7000 relays in total, with almost 2000 being exit relays. I will round these figures up into 7000 – 2000 = 5000 middle relays and 2000 exit relays.

Assuming the attacker owns 10 middle relays and 10 exit relays, the probability of them getting to control the whole circuit is

P = 10/5000 * 9/4999 * 10/2000 ~= 1.8e-8 

which is very low. However, once you factor in the enormous amount of Tor circuits being established (could not find a reliable figure anywhere, will gladly edit one in if someone has it), wouldn’t this agent be able to consistently get complete circuits through their relays and, as a consequence, have complete access to the data it was relaying?

I understand that some of the data through the circuits would also be using TLS, but at least some of it should be plaintext.

It may also be worth pointing out that if this is a really well-funded agent, they might have substantially more than 20 relays at their disposal.

How is miss chance calculated if a caster has Entropic shield active and is inside Darkness spell?

My question is simple. I have a warlock that has following invocations:


“This spell causes an object to radiate shadowy illumination out to a 20-foot radius. All creatures in the area gain concealment (20% miss chance). Even creatures that can normally see in such conditions (such as with darkvision or low-light vision) have the miss chance in an area shrouded in magical darkness.”

Entropic warding:

“A magical field appears around you, glowing with a chaotic blast of multicolored hues. This field deflects incoming arrows, rays, and other ranged attacks. Each ranged attack directed at you for which the attacker must make an attack roll has a 20% miss chance (similar to the effects of concealment). Other attacks that simply work at a distance are not affected.” Devil’s Sight: “You gain the visual acuity of a devil for 24 hours. You can see normally in darkness and magical darkness out to 30 feet.”

Devil’s Sight:

You gain the visual acuity of a devil for 24 hours. You can see normally in darkness and magical darkness out to 30 feet.

With entropic warding I get 20% miss chance on ranged attacks as deflection. In addtion, Darkness grants 20% miss chance if the caster is in it. If I am inside darkness and I have entropic warding on, do my miss chances stacks up to 40% (given I get ranged attack) or do I roll miss chance twice as twice with 20% with each roll.

When is it best to use the second chance repalcement algorithm?

I’m going through ‘Operating Concepts’ by Silberschatz, Galvin and Gagne (The Dinosaur Book) and it mentions the Second-Chance Algorithm (not enhanced) as an improvement on the FIFO replacement algorithm.

My question is, is there ever a case where this algorithm would perform better than, say, the Least Recently Used algorithm or even something like the Farthest-in-Future Algorithm? The book describes how the algorithm works but doesn’t offer a lot of information on when it would be useful, other than just in improving ‘FIFO’.

How to practically handle the 33% chance to be unable to cast Wish ever again?

The description of the wish spell states:

Finally, there is a 33 percent chance that you are unable to cast wish ever again if you suffer this stress.

I’m trying to figure out how to handle this limitation. The rest of the question assumes that the caster is casting wish for purposes other than casting a level 1-8 spell.

My grasp of statistics is OK. My DM’s? Less so.

How I expect it works: every time I cast wish there is 33% chance I may never cast it again. But I want to cover the naïve questions I expect that my DM is going to have. For instance:

  1. I want to know if a caster is bound to not be able to cast wish anymore, meaning that in the best case after 33 casts without suffering the stress, the caster will definitely suffer it on the 34th cast.

  2. I would like to know who or what decides that 33 percent is achieved. Does a die have to be rolled? Must another random mechanism be used? And who triggers it: the DM or the player?

  3. If the DM/player wants to roll, can the roll be a d6, or must it be a d100? The spell says “33.0” percent, right? Not 1/3 (or 33.333… percent). So a d6 can’t be used, can it?

  4. Can feats, abilities or spells altering the roll be used?

Are there any ways to regain the ability to cast Wish after suffering the 33% chance to never be able to cast it again? [duplicate]

Are there any ways to restore your ability to cast Wish after suffering from the stress described in the final paragraph and losing your ability to cast it?

From the description:

The stress of casting this spell to produce any effect other than duplicating another spell weakens you. After enduring that stress, each time you cast a spell until you finish a long rest, you take 1d10 necrotic damage per level of that spell. This damage can’t be reduced or prevented in any way. In addition, your Strength drops to 3, if it isn’t 3 or lower already, for 2d4 days. For each of those days that you spend resting and doing nothing more than light activity, your remaining recovery time decreases by 2 days. Finally, there is a 33 percent chance that you are unable to cast wish ever again if you suffer this stress.

What is the maximum possible chance to critically hit?

What is the highest possible chance to critically hit? This can include content from any official source as well as unearthed arcana.

For example the level 15 Champion Fighter can critically hit on a roll as low as an 18. If the character has advantage they roll two dice. The Elven Accuracy racial feat allows you to reroll 1 of the d20s essentially creating double advantage. If you also take the Lucky feat you can roll an additional d20 essentially creating triple advantage.

Note I’m looking for chance for the die roll to result in a crit NOT factoring in the fact that any hit on a paralyzed or unconscious enemy or features like the rogue’s Assassinate feature.

I’m looking for both the methods used and the overall %chance to hit. For reference the character does not have to be viable in a game, this is pure theory-crafting.
