Amazoness Fighting Spirit

If an "Amazoness" monster or "Amazon Archer" attacks a monster with higher ATK, the attacking monster gains 1000 ATK during damage calculation only

ocg ruling:
The ATK-increasing effect of "Amazoness Fighting Spirit" does not start a Chain Link.

mean it is continous effect
same go with skyscraper~

special notice (example use skyscraper since both of them are same)
Example : Injection Fairy Lily and Skyscraper

Player A has "Skyscraper" in his/her Field Spell Card Zone and "Elemental Hero Wildedge" in Attack Position. He/she attacks her opponent's Attack Position "Injection Fairy Lily". During damage calculation, his/her opponent activates "Injection Fairy Lily's" effect, increasing its ATK to 3400. After "Injection Fairy Lily's" effect resolves, "Skyscraper's" Continuous Effect is applied to increase the ATK of "Elemental Hero Wildedge" to 3600.
