Resistances

Characters and Mobs may be affected by Resistance, Immunity, or Susceptibility to certain attack types.

Collectively, this is known as the "RIS" in Smaug 1.8 code, and I will use that term on this page so I don't have to keep typing "Resistance/Immunity/Susceptibility"

All of these work similarly, so I'll lump them all on this page named "Resistances" since that's what player typically see and hear about the most.

About

Help File: RESISTS IMMUNITIES SUSCEPTS Status Command: aff by

Note that RIS affects are not displayed in 'Score', or sent by MSDP, the only way to view them is via the 'aff by' command.

• RIS affects have two traits:
  • Attack Type: There are 17
  • Percentage: How much damage is decreased/increased by the Resist/Sucept. ("Immune" negates damage 100%, so isn't shown with any percentage)

RIS Attack Types

There are 17 types of attack for which one can be RIS. It is not known if a given attack counts as one of these type for which there is a resistance/susceptibility. Also, there are additional attack types for which there is no RIS. Figuring out which attacks in the game are impacted by which RIS requires manual testing in the game.

Fire, Cold, Electricity, Energy, Blunt, Pierce, Slash, Acid, Poison, Drain, Sleep, Charm, Non-Magic, Magic, Paralysis, Holy, Unholy

I like to group them like this:

   General: Magic, Non-Magic
 Elemental: Fire, Cold, Electricity, Energy
  Tactical: Blunt, Pierce, Slash
  Chemical: Acid, Poison
    Mental: Drain, Sleep, Charm, Paralysis
 Spiritual: Holy, Unholy
     Other: Blindness, "Plus1" - "Plus6".

Remember those categories have nothing to do with anything, I just made them up to help sort the 17 into somewhat logical groups.

Notes:

• Non-Magic: Pertains to non-magic WEAPON attacks. Not kick/punch stuff.
• Magic: Pertains to magic weapons, most spells (not all), and all spelldowns (even if they are technically a 'skill' not spell)
• Blindness: RIS impacts the duration of the blindness, shorter/longer.
• Plus1: These relate to attacks with 0 or less hr, like kick/punch/choke, or weapons like Nasr.
• Plus(X): These relate to attacks with (X-1) hr.

Other Attack Types

There are of course attacks/skills which are not classified as one of those RIS affect types.

I'll leave it to you to figure out which those are, but the big ones most everyone knows about are these AV alpha attacks:

• Spiral Blast
• Rend
• Gash
• Shieldbash

While mobs might have other defenses against those, it is currently believed those attacks are not impacted by RIS.

Resistance

Damage to the player from an attack type you are resistant to is decreased by the percentage shown in 'aff by'. Or so you would think.

Actually, realms lies about this a bit. The true reduction does not match the displayed percentage reduction in 'aff by'.

The in-game 'aff by' display of 40% is actually the maximum resistance you can have, and in truth this results in 20% actual damage reduction. Here's a handy chart of displayed values vs. true damage reduction:

If 'aff by' says:	5%	10%	15%	20%	25%	30%	35%	40%	+40%
True damage reduction:	3%	10%	12%	14%	15%	17%	18%	20%	20%

This is testable by taking damage from an obvious damage attack type, let's say fire, in a place where it's easily repeatable, let's say a simple room prog you can trigger easily. Eat the damage with no resistance, let's say its 100hp. Add some resistance and do it again. Track the change in damage, and do some math.

Susceptibility

Resistance and Susceptibility are exactly equal and opposite, so everything that's true about resists hold for susceptibilities as well, just in the opposite way.

The table above that shows 'True damage reduction' for resistances would just become "Extra damage modifier" and you would feel 3%, 10%, 12%, etc, more damage from those attack types to which you are susceptible.

Immunity

This mostly pertains to mobs, who are frequently immune to a buncha crap so you have to figure out how to fight them. For example, they might be immune to magic weapons, or slashing weapons, or entirely immune magic, whatever.

On the player-side of things, the only immunity I'm aware of players can use is the Mage's "Path of Countermagick" spell "Inviola Magicka" which makes you immune to magic for a short period.

Buffs/DeBuffs

As the help file states, RIS affects can be caused by "spells, equipment, class or race".

Most commonly, potions are used to buff resistance, and spelldowns are used to apply susceptibilities to mobs.

This table shows the most common and accessible spells that buff/debuff RIS (largely from tanksets).

• There are many more which are class specific I am not including here. Learn your class to find all the options.
  • For example, Mages and Nephandi's get a LOT of spells/skills which grant additional RIS buffs/debuffs, especially for the things listed below with no options.

Type	Susceptible	Resist
nonmagic	unravel defense	shadowform, eldritch sphere
magic	unravel defense	antimagic shell, eldritch sphere
fire	blazebane	blazeward prismatic shield
cold		inner warmth prismatic shield
electricity		grounding prismatic shield
energy	ethereal funnel	ethereal shield
blunt		confidence
pierce	razorbait	dragonskin, confidence
slash	swordbait	demonskin, confidence
acid		acidward
drain		resilience
holy		nimbus of light
