Pet Runestones are magical abilities that can be taught to compatible Meta Pets. Once learned, combat runes can trigger from the pet's melee attacks, unleashing elemental damage, area attacks, debuffs, healing, or crowd-control effects.

To teach a pet a runestone ability:

• Open the pet's Creature Menu.
• Use Apply Runestone.
• Target a runestone in your backpack.
• If the pet has an open ability slot, the runestone is consumed and the ability is learned.

Each pet has a limited number of runestone ability slots.

The pet gump has a Runestone XP toggle next to Apply Runestone.

• Runestone XP: On shows rune XP gain messages.
• Runestone XP: Off hides rune XP gain messages.

This only controls system messages. It does not affect how much XP the runes gain.

Most combat runes trigger from successful melee hits.

When your pet lands a melee hit:

• The system checks if the pet's shared runestone proc cooldown is ready.
• The pet rolls its learned combat runes.
• Only one runestone can trigger from that melee hit.
• If a rune triggers, the pet enters a shared runestone cooldown.

This means:

• More runes give your pet more variety.
• More runes do not allow several runes to fire at once.
• One melee hit can only trigger one combat runestone.
• Stacking many runes does not create unlimited proc spam.

Combat runestone proc chance increases with rune level.

If a pet has several runes, their chances are combined into a weighted table, but the total proc chance is capped.

Example:

The pet does not get three separate rolls. Instead, the system chooses one possible rune from the weighted table.

So several runes increase ability variety, not raw proc spam.

Combat runes share a global proc cooldown.

• Current global cooldown: 10 seconds
• The cooldown starts after a combat rune successfully triggers.
• Gold Find is separate and does not use the normal combat rune proc system.

Some runes also have their own additional cooldowns.

This is especially important for DOT, field, drain, and poison runes so they cannot refresh endlessly.

Examples:

Damage runes scale with level.

Damage is shown before target resistances.

Some runes deal their damage in different ways:

• Single-target runes hit one enemy.
• AOE runes can hit multiple enemies.
• DOT runes split their damage over time.
• Utility runes may deal less damage because they also stun, paralyze, debuff, taunt, heal, or apply poison.

AOE runes are intended to hit multiple valid targets, but each target should only be hit once per proc by the main effect.

Runestone abilities are designed for creature combat.

They should not damage:

• Players
• Controlled pets
• Summoned creatures
• Dead bonded pets
• Invalid or unreachable targets

Runestones are meant to hit hostile creatures only.

Each runestone ability has its own level and experience.

Runes no longer gain XP from simply activating.

Instead, runes gain XP when the Meta Pet gains valid kill XP.

When the pet kills a valid monster:

• The pet gains normal Meta Pet XP.
• Eligible learned runes receive rune XP from that same kill.
• XP is split between eligible runes.
• Runes that are max level do not take a share.
• Runes waiting for upgrade do not take a share.
• Gold Find is separate and does not use normal combat rune kill XP.

Example:

This means runestone leveling follows the same kind of grind as Meta Pet leveling.

Runestone XP requirements use the Meta Pet-style level curve.

Level 10 is the current maximum rune level.

When a runestone reaches enough XP to level up, it does not level automatically.

Instead, it becomes ready for upgrade.

The pet gump will show that the ability is ready.

To upgrade it:

• Open the pet's Creature Menu.
• Use Upgrade Rune / Apply Runestone.
• Target the same type of runestone in your backpack.
• The matching runestone is consumed.
• The learned ability gains one level.
• The rune's pending upgrade state is cleared.

Example:

• Your pet has Flameburst Level 4.
• Flameburst reaches its XP requirement.
• The gump says it is ready.
• You insert another Flameburst Runestone.
• The ability becomes Flameburst Level 5.

A different runestone type will not upgrade it.

• Combat runes proc from pet melee hits.
• Only one combat rune can trigger at a time.
• Proc chance scales per level
• Combat runes share a cooldown.
• DOT and field runes may also have their own extra cooldowns.
• Utility runes may deal less damage because they add extra effects.
• Rune XP comes from valid Pet kill XP, not from rune activation.
• Rune XP is split between eligible learned runes.
• To level a rune, it must reach XP requirement and then consume the same type of runestone.
• Gold Find is separate from the normal combat rune system.
