Qual é o bônus máximo Stealth possível?

13

I realised we do not have a version of this rather (in)famous optimization problem: What is the maximum possible bonus to a Dexterity (Stealth) check?

Bonus is here taken to mean anything that is added to the result of the d20. Any added dice can be assumed to roll their maximums.

Constrains:

  • Official, non-UA material only

  • 20 level character with any number of boons

  • Magic items are fine, except items which increase ability scores above 20.

  • Assistance from up to 4 allies

  • Do not use play style variant rules (such as proficiency dice). Character creation variant rules (such as multiclassing and feats) are ok.

  • The bonus only has to be applied to a single check

  • No using desejo for anything other than replicating a spell of 8th level or lower.

At most +146.

This does not include the 20 from the d20. The maximum rolled result would be 166.

Requisitos:

Your character must have...

Your magic items must include...

Your allies should include...

The Math:

Start with your character's Dexterity modifier. Without magic items, you can get 20 Dexterity. You then ask your DM for five Ability Score Improvements (listed as epic boon alternatives), raising your Dexterity to 30. Your Dexterity modifier is + 10.

As a 20th level character with the Ioun Stone of Mastery, your Proficiency bonus increases by 1, from +6 to +7. And with Expertise in Dexterity (Stealth), you add your Proficiency bonus twice to the stealth check. This becomes a + 14 bônus.

Also, your Boon of Undetectability adds + 10 to Dexterity (Stealth), and your Stone of Good Luck gives an extra +1 to ability checks. So far, you have a total +35 Stealth bonus, without any temporary or situational benefits.

But wait, there's more! As a Ranger, you cast passar sem deixar rasto, which gives a + 10 bonus for the next hour. Then you take a minute to camouflage yourself via Mimetismo, which will give you another + 10 bônus.

This next hour will be a short rest. Your druid ally uses Hearth of Moonlight and Shadow to give everyone a +5 bonus to Dexterity (Stealth).

Your bard ally gives you a d12 Inspiration die. And if they're wearing the Lost Crown of Besilmer, they can use their next bonus action give you another + 1d6.

If your Wild Magic sorcerer ally can see you, then their Bend Luck feature can add + 1d4 to your check. The sorcerer should then run away and hide elsewhere, lest they randomly explode and accidentally reveal your location.

O orientação spell adds another + 1d4. Both the Dark One's Own Luck feature and your Boon of Luck each add + 1d10. Your four allies' Boons of Fate each add another + 1d10.

The total bonus is +(10 + 14 + 10 + 1 + 10 + 10 + 5 + 1d12 + 1d6 + 2d4 + 6d10) = + 146 máximo.

Arbitrarily large

A 20th level character with the Boon of Fate can add +1d10 to the ability check of one target within 60 feet as a non-action. Since Epic Boons are not " spells, class features, feats, racial traits, monster abilities, [or] magic items" (DMG errata) and no other text includes epic boons within the definition of 'game features', they are not subject to the DMG errata that broadened the prohibition on magical effects with the same name stacking to all 'game features'. Therefore, a character-- though limited to only one copy of the Boon of Fate-- can benefit from infinitely many applications of said boon on a single roll.

A 20th level Wizard can cast simulacro. With the Boon of High Magic they can do this via Desejo twice per day without needing material components. With the Boon of Spell Recall you can do it three times per day. With a Tomo da Língua Fervida they can do it four times per day. With more Tomes of the Stilled Tongue they can do it more times, though they will need to attune a new tomar after each casting.

A 20th level Wizard lacking a tome of the stilled tongue and epic boons can store a casting of simulacro em uma glifo de proteção. This does not make the simulacrum 'appear as close as possible... and attack' when the glifo is activated, because simulacro creates a friendly, rather than hostile, creature. After creating such a glyph, the wizard can regain spell slots without losing access to the simulacro soletrar.

Either way, a 20th level Wizard can create a simulacrum of themself able to itself create a simulacrum via Desejo. The wizard can then create another simulacrum, dispelling the first one but leaving the one it created unharmed, as the second simulacrum makes another copy of the wizard. This allows the simulacrum creation process to be exponential rather than linear in growth-- each surviving simulacra creates perhaps three other dying simulacra who make 1 surviving simulacra each, the whole process of which takes no more than 6 rounds. After 24 hours, as an example, such a wizard would have 3^67200 simulacra, or around 35 decmilliasescensexoctogintillion simulacra.

Unlike most checks, a Stealth check's total lasts "until you are discovered or stop hiding", and is reused against the Wisdom(perception) total of a chacter that is searching for you. Our wizard, then, can make a stealth check to hide from a rat but not the simularcra. The simulacra within range can add 1d10 each to the stealth check via their Boons of Fate, and then teleport out of the way via a contingência spell tied to a mudança de avião. More can then teleport in via an action, add to the check total, and then teleport out via contingência, all within each of their turns. With a sufficiently large bag of rats, then, to ensure a large number of initiative counts, even all 35 decmilliasescensexoctogintillion simulacra should be able to efficiently discharge their stealth buffs into you within a few rounds. That would give you approximately a + 175 decmilliasescensexoctogintillion bonus to your stealth check. Note that since Perception checks não carry over a total to new checks like this, you can't pump them up to astronomical heights in the same way-- if you are careful to protect against direct observation and have even just 10 full 60' spheres of simulacra buff your Stealth there's no way anyone is ever going to find you unless you give yourself up-- they can't get more of a bonus to Perception than you have to Stealth.
