All Pokemon creatures contain their own moves. They’re assigned to their own characteristics and have unique strengths and weaknesses in both attack and defense.
If a trainer is well-aware of its using Pokemon’s type chart; it gets advantageous for the trainer. In this way, a trainer can make much more damage than normal.
A single-type, let’s for suppose, take an example of Water attack against Ground-type Pokemon, will advantage in form of producing a double normal damage.
These advantages are also multiplied and it all depends upon the situation. For instance, a double-type will produce quadruple damage. Therefore, it proves how different types have their own features and respective advantages. In such advantageous cases after an attack is made, you will see a message appearing on the screen, ‘It’s super effective!’
However, these single- and double- types don’t only effect positively. Conversely, they will disadvantage in a way that will afflict half and quarter normal damage. And thus the game will reveal a message, ‘It’s not very effective…’
In Same Type Attack Bonus, there’s also another advantage you can gain. If a Pokemon is with the same type as its move is, for example a Fire-type move being given by Fire-type Pokemon, the power of the move gets increased.
In this case the damage is done 1.5 times normal. And if this situation occurs with a Water-type Pokemon attacking with a Water-type move to a Ground or Rock type Pokemon, it will give you six times (that’s 2*2*1.5) normal damage.
Here this type chart will display you the strengths and weaknesses of each typed Pokemon. Take a view at the left hand side of the chart and see Pokemon’s attacking type. Then, look across the chart to understand how effective each type is against its opponent.
0 corresponds to No effect
½ corresponds to not very effective (50%)
Vacant spaces correspond to normal (100%)
2 corresponds to Super-effective (200%)
Note: This chart is for Pokemon games (2013 onwards) – such as Pokemon Go, Pokemon X/Y, OR/AS and Sun/Moon. Older games type charts are a slight different.
