Vulnerabilities
Weaknesses that can be exploited by others.
In games where one can suffer damage or other adverse effects, entities may be more vulnerable to some attacks than others. Having such Vulnerabilities mean that player have to adjust their gameplay to minimize the likelihood of these being exploited, but when others have them it can instead provide opportunities. If enemies are suspected of having Vulnerabilities this can lead to gameplay aimed at confirming the presence or absence of these.

Examples
In the fourth edition of Dungeons & Dragons, monsters that are vulnerable to a specific form of attack simply take a predetermined extra amount of damage each time such an attack hits them. GURPS has the disadvantage Vulnerability that multiplies damages from certain types of attack depending on how vulnerable one is.
The design of weapons and monsters in Quake have been described as having chains of vulnerabilities where one monster is vulnerable to one type of weapon, but that weapon makes the player vulnerable to another type of monster[1].
The vampires in the Elder Scrolls series take damages if they are outdoors when the sun is up. The werewolves found in the Bloodmoon expansion of Morrowind take double damage from silver weapons.
Using the pattern
The design of a Vulnerability consist of deciding which have it, what causes it, and what the effect is.
Vulnerabilities can be applied equally well to Avatars, Characters, and Units and this may be those under players' control or their Enemies. Probably the most commonly used cause for Vulnerabilities is different types of Damage (e.g. fire, electricity, etc.). Vulnerabilities can be used to create Environmental Effects that only affect a small group of Characters - for example making vampires take damage when exposed to the sun does help define a gameplay difference between outdoor and indoor areas. Vulnerabilities can of course also be used to increase the Damage of already dangerous Environmental Effects.
Effects of Vulnerabilities often affect Damage, or give

The effects of Vulnerabilities may be ongoing if they are linked to Environmental Effects.
Although Vulnerabilities is incompatible with complete Invulnerabilities the patterns can be used together when applied to different types of attacks or effects. An exception where complete Invulnerabilities work with Vulnerabilities is when a single Vulnerability provides an Achilles' Heel to an otherwise invulnerable entity.

Consequences
Introducing Vulnerabilities in games modulate Damage, typically affecting gameplay related to Combat; Movement can also be affect when Vulnerabilities is used in relation to Environmental Effects. Since the effect of this is that players may have to switch between different Weapons or Powers depending on who they encounter, this provides Varied Gameplay. Having to adopt different defensive tactics due to one's own Vulnerabilities can likewise produce Varied Gameplay.
Knowing what Vulnerabilities exist in games is Strategic Knowledge, and lead to Strategic and Tactical Planning when these depend on which Powers or Weapons are used. When the existence of Vulnerabilities is known but not exactly which entities have which Vulnerabilities this leads to Gain Information goals, and Experimenting with Enemies to see what affects them more or less than other Enemies.
Making closed chains of entities that are vulnerable to one another but not reciprocally so creates Rock-Paper-Scissors structures.
