Talk:Draconic Resilience

Does not work with Barb or Monk's AC boost.

• Hi, thank you for notifying us. This is written on both the Unarmoured Defence pages and Mage Armour, so I'm not sure why it's not here. Nattern (talk) 08:03, 29 February 2024 (CET)

Dragonic Resilience is the same as Mage Armour, they both set the base armor to 13 when not wearing an armor. However, Unarmoured Defence "adds" your Constitution Modifier to the base armor when not wearing an armor. This in my opinion should stack. RYANZKIE (talk) 05:47, 13 March 2024 (CET)

That's not how it works, Unarmoured Defence doesn't "add AC". Even in tabletop these are different ways of gaining AC, each with their own formula. You can't mix these formulas, only one applies. The D&D rulebook says "Some spells and class features give you a different way to calculate your AC. If you have multiple features that give you different ways to calculate your AC, you choose which one to use." This was done specifically to avoid stacking, which is part of the whole "bounded accuracy" philosophy in 5e, where all numbers are deliberately kept smaller Sparkle (talk) 06:41, 13 March 2024 (CET)

It is clear in its definition that it adds modifier to the AC.

Description

Your body is as resilient as any armour. While not wearing armour, you add your Constitution Modifier to your Armour Class. Wearing Heavy Armour impedes your Rage.

By formula this is simply

Base AC + Constitution Modifier

In the case of Dragonic Resilience, the formula as per definition is

Base AC = 13

Tell me if my understanding is wrong. RYANZKIE (talk) 10:24, 13 March 2024 (CET)

Here is the code for Draconic Resilience and Unarmoured Defense (Barbarian):

ACOverrideFormula(13,true,Dexterity)
ACOverrideFormula(10,true,Dexterity,Constitution)
The first number is Base Armour Class, the second is if bonuses are allowed (like a shield, spells and enchantments. This is set to false for Barkskin), and after that any ability modifiers that should be added to the AC. As you can see they both have different formulas and therefore cannot stack.

RYANZKIE, you're arguing against the rulebook itself, which quite literally states that these are different ways of calculating AC, and that every character only uses ONE formula, and not several formulas mashed together.

I think you're tripped by the word "adds", but that doesn't mean you're free to add a CON modifier to any barbarian's AC, just because he doesn't wear armour. The concept is "base AC + DEX modifier", and different situations define "base AC" differently. When wearing armour, base AC = the AC from the armour. When using Mage Armour, base AC = 13. When Using Draconic Resilience, base AC = 13. When unamoured and a barbarian, base AC = 10 + CON modifier. When unamoured and a monk, base AC = 10 + WIS modifier. So for the barbarian and the monk this base AC is variable and depends on your stats, that's why it says "add CON/WIS modifier", but that doesn't mean you're free to add that to the other formulas. Every case has its definition of base AC and there's no cross pollination, the rulebook says "you choose which one to use". Sparkle (talk) 18:18, 13 March 2024 (CET)
