# SB (Strike Back)

**Strike Back**(SB) is a feature that gives the weaker team to have a chance to win in the fight for S-treasure.

Strike Back will be automatically triggered when the following conditions are met:

- The S-Treasure has been opened
- Explorer and Assistant put Porians in S-Treasure
**ESB**will take place if EP<AP and**ASB**Will take place if AP<EP

(*) SB will not activate when EP = AP, and Explorer will win when EP = AP.

The power of a team in Strike Back index will be calculate based on the 4 Porians of your team in the mission.

The Strike Back formula is:

*Powers(in S-Treasure)*

**100%**+ Powers(in normal cell)*

**40%**(rounded down)*

For Example:

*In an AP mission, you have 2 Porians in S-Treasure cell with power**325**and**330**, and 2 Porians in normal cells with powers of**301**and**314**.**The power of Porians in the normal cell will be calculated such as:*

*301*40%=120.4**is rounded down to*

*120*

*314*40%=125.6**is rounded down to*

*125**The total power of AP team will be calculated accordingly:*

*AP = 325 + 330 + 120 + 125 = 900*This chance is measured in percentage, and is represented as the

**SB**value in each game. The formula of SB is as follows:

$ESB = \min\left(49\%, \frac{100\%}{(\left\lfloor \frac{AP - EP}{20} \right\rfloor+ 1.5)\sqrt{AP - EP})}\right)$

$ASB = \min\left(49\%, \frac{100\%}{(\left\lfloor \frac{EP - AP}{20} \right\rfloor+ 1.5)\sqrt{EP - AP})}\right)$

The chart below illustrates how SB varies according to the difference between AP and EP.
