Boost Types

Boost Types

Every boost, boost area and charm has one of the 10 types below. This page explains exactly what the multiplier changes for each one.

Important

In commands, type names must be written in UPPERCASE exactly as shown in the ID column (for example /sparkles boost start SPAWN_BUCKET ...). Tab completion suggests them for you. In config files, type names are case-insensitive, so "shiny" and "SHINY" both work.

Overview

ID	Display Name	What It Boosts	Charm
SHINY	Shiny	Shiny odds	Shiny Charm
EXPERIENCE	Experience	Experience gained	Experience Charm
HIDDEN_ABILITY	Hidden Ability	Chance of wild spawns having their Hidden Ability	Veiled Charm
EV	EV	EVs gained	Effort Charm
IV	IV	IVs of Pokémon you catch, hatch or revive	IV Charm
BERRY	Berry	Berries harvested	Berry Charm
CATCH_RATE	Catch Rate	Catch rate	Catching Charm
MARK	Mark	Chance of marks on Pokémon you catch or revive	Mark Charm
ALPHA	Alpha	Alpha spawn chance	Alpha Charm
SPAWN_BUCKET	Spawn Bucket	Chance of rarer spawn buckets	Bucket Charm

The display name is what %boost_type% shows in messages. See Placeholders.

Tip

Any type can be blocked for specific Pokémon using persistent_data_key_blacklist in Config.json. By default, the IV boost skips raid Pokémon.

Shiny — SHINY

Divides the shiny rate by the multiplier. With the default Cobblemon rate of 1/8192, a 2x boost makes it 1/4096. Shiny multipliers from different sources multiply together (see How-It-Works), and the rate can never go better than 1/1.

Check it with %player_shiny_rate%, which shows the player's final rate (e.g. 4096.0 for 1/4096).

Experience — EXPERIENCE

Multiplies the experience a player's Pokémon gains, rounded to the nearest whole number.

• Experience given by commands is never boosted.
• Rare Candies and other experience items are skipped when experience_booster_ignores_candy is true.
• Experience given by other mods is skipped when experience_booster_ignores_sidemod_source is true.

Hidden Ability — HIDDEN_ABILITY

Gives Pokémon that spawn near a player a chance to spawn with their Hidden Ability. The chance is:

hidden_ability_booster_base_chance × multiplier   (capped at 100%)

With the default base chance of 0.05 (5%), a 2x boost gives each spawn a 10% chance and a 4x boost gives 20%. With no boost (1x), this type does nothing, so normal Cobblemon Hidden Ability odds apply.

Check it with %player_hidden_ability_chance%.

EV — EV

Multiplies the EVs a player's Pokémon gains. The multiplier is rounded down to a whole number, so 2.5x acts as 2x and 1.5x has no effect. Use whole-number multipliers for this type.

• Vitamins and other EV items are skipped when ev_booster_ignores_vitamins is true.
• EVs given by other mods are skipped when ev_booster_ignores_sidemod_source is true.

IV — IV

When a player catches, hatches or revives a Pokémon from a fossil, each of its IVs is moved part of the way toward a perfect 31. How far depends on the strength:

strength = (multiplier − 1) / (multiplier − 1 + iv_booster_strength_constant)
new IV   = current IV + (31 − current IV) × strength

With the default iv_booster_strength_constant of 4:

Multiplier	Strength	An IV of 11 becomes
1x	0%	11
2x	20%	15
3x	33%	18
5x	50%	21
9x	67%	24

Higher multipliers keep getting closer to 31 but never make every IV perfect. A lower constant makes the boost stronger.

Check it with %player_iv_strength%.

Berry — BERRY

Multiplies the number of berries a player gets when harvesting a berry tree, up to a full stack. Like EV, the multiplier is rounded down to a whole number.

Catch Rate — CATCH_RATE

Multiplies the catch rate of Pokémon a player throws a Poké Ball at, up to the maximum catch rate of 255.

Mark — MARK

When a player catches a Pokémon or revives one from a fossil, it gets an extra roll for marks, with each mark's normal chance multiplied by the multiplier. This type has no effect at 1x.

Alpha — ALPHA

Makes Alpha Pokémon more likely to spawn near a player. MoreSparkles scans Cobblemon's spawn pool for every spawn entry that can produce an Alpha (including herds), then multiplies both the chance of picking those entries and the weight of the spawn buckets they're in.

This works with custom Alpha spawn files too, whatever bucket they're in.

Check it with %player_alpha_bucket_chance%, which shows the combined chance of rolling a bucket that contains Alphas.

Spawn Bucket — SPAWN_BUCKET

Evens out the spawn bucket weights near a player, so uncommon, rare and ultra-rare Pokémon spawn more often and common ones less often. Each bucket's weight is raised to the power of 1 / multiplier, which pulls every bucket toward equal odds as the multiplier grows. The boss bucket keeps the same share relative to the other buckets.

This type doesn't make every bucket equally likely at any normal multiplier; it narrows the gap between them.

Check it with %player_bucket_chance <bucket>%, for example %player_bucket_chance rare%.
