Tested Encourage.

Its boost is 1,3x (average of 100 dmg will now be average of 130 dmg)

I recorded a test using Flare Blitz (which is boosted, BTW). With the damages in this video it doesn't become clear whether the boost is of 1,2x or of 1,3x, but after I recorded it I did some more damages and they definitely put it into 1,3x range.

(it's still processing as of now)

Also, on further testing, both of these Hihidarumas did the same damage to each other when using Strength. So, only moves that have secondary effects are boosted.
