I didn't understand this phrase.
This means that with lower attack, all damage is multiplied by 1.3
Just like defense, all received damage is multiplied by 0.8 (0.85 SoD)

Yes, offense adds 30% to damage, no matter who says what ) I saw it myself )
Hit a goblin with an angel that has offense and calculate the damage ;)
