Type Effectiveness

=Description= An attacking Pokémon's damage output against a defending Pokémon is calculated as follows. The attacking Pokémon is treated as having a single type (mono-type). The type that is used is the one that does the most damage against the defending Pokémon, including any Gem modifications to the type-efficacy multiplier. In cases where the defending Pokémon is a mono-type, it will treat it as being a dual-type of said type (for example, a pure Normal Pokémon would be treated as Normal / Normal), so type effectiveness will be twice as effective (or ineffective). The sum of all valid Party Pokémon (non-breeding) with modifiers (Weather, XAttack) is the total Pokémon Attack. Below are some examples to articulate this calculation.

Examples

 * Lanturn.png Lanturn (attacking) vs Gyarados.png Gyarados (defending) - Lanturn is dual electric-water typed and Gyarados is dual water-flying typed. Lanturn's electric type is 4x effective against Gyarados (2x for both water and electric) so this is the type that is used. Lanturn's attack against Gyarados is increased by a factor of 4 (4x) as per the type multiplier.


 * Venusaur.png Venusaur (attacking) vs. Magcargo.png Magcargo (defending) - Venusaur is dual grass-poison typed and Magcargo is dual fire-rock typed. Venusaur's grass type is 1x effective against Magcargo (normal-effective, 2x effective against rock while 0.5x effective against fire) while Venusaur's poison type is 0.5x effective (not very-effective). Thus, Venusaur's grass type is the type that is used. Venusaur's attack against Magcargo is neither increased nor decreased as per the type multiplier of 1 (1x).


 * Venusaur.png Venusaur (attacking) with fully boosted not-very effective Poison Gem vs. Magcargo.png Magcargo (defending) - Venusaur is dual grass-poison typed and Magcargo is dual fire-rock typed. Venusaur's grass type is 1x effective against Magcargo (normal-effective, 2x effective against rock while 0.5x effective against fire), while Venusaur's poison type is 1.5x effective (not very-effective) with the Gem multiplier. Thus, Venusaur's poison type is the type that is used. Venusaur's attack against Magcargo is increased by a factor of 1.5 (1.5x) as per the type multiplier.


 * Gengar.png Gengar (attacking) vs. Kangaskhan.png Kangaskhan (defending) - Gengar is dual ghost-poison typed and Kangaskhan is mono normal typed. Gengar's ghost type is 0x effective (immune) against Kangaskhan while Gengar's poison type is 1x effective (normal-effective). Thus, Gengar's poison type is the type that is used. Gengar's attack against Kangaskhan is neither increased nor decreased as per the type multiplier of 1 (1x).


 * Kangaskhan.png Kangaskhan (attacking) vs. Gengar.png Gengar (defending) - Kangaskhan is mono normal typed and Gengar is dual ghost-poison typed. Kangaskhan's normal type is 0x effective (immune) against Gengar's ghost type. As this is the only type of Kangaskhan, Kangaskhan's normal type is used. Thus, Kangaskhan's attack against Gengar is 0 as per the type multiplier of 0 (0x).


 * Blastoise.png Blastoise (attacking) vs. Ninetales.png Ninetales (defending) - Blastoise is mono water typed and Ninetales is fire type but the game considers it as a dual fire-fire typed. Blastoise's water type is 2x effective against fire and, since the game considers Ninetales a dual-type, it will add another 2x to the calculation making Blastoise's attack deal 4x instead of 2x. If very effective Water Gems has been fully boosted where the multiplier becomes 3x then Blastoise's attack will deal 6x (3x times 2) instead.

Type Effectiveness Modifiers

 * Very = "Super Effective" - (2x)
 * Normal = "Effective" - (1x)
 * Not-Very = "Not-Very Effective" - (0.5x)
 * Immunue = "Not Effective" - (0x)

Type Effectiveness Chart
Below is a table showing the effectiveness of each Pokémon type. It can be used to prioritize Gems upgrades.

=Practicality=

See Gems for a list of optimal farming routes for each type of Gem.

A breakdown of how much damage each type contributes to total damage, absent any gem boosts, can be seen by using the Damage Calculator screen in the Start Menu. Types that do the most damage generally should be upgraded with gems first.

=Trivia=

As of PokéClicker version 0.5.8 the following categories were removed from the Gem Case because they have no effect (they do not increase damage) when invested into.
