Guarding

Duration of shields applied to allies is increased by 25%/50% of your Shield power.

The Effect does not affect the shields applied to self.

Example Formula:
Your a Lightbinder, Shield Power is 30%, and you got Guarding lv.2.

Unstable Shield lasts for 8 seconds.

50% of the 30%= 15%. . . 8 sec x 15% = 1.2 seconds extra timespan.

But the game rounds in down, so you get 1 extra second.
