"When you defeat Warmech Lv.40 and Lv.70, you can get Armor of Light+2 Lv.50 and Armor of Light +4 ."
What does that mean? The sentence is grammatically incorrect and does not clearly convey the Raid event correctly.
Did you mean, "When you defeat Warmech at Lv.40 and Lv.50, you receive an Armor of Light+2, when you defeat it at Lv.70 you receive an Armor of Light +4."
