Gold x330000 Strong in PvP
Great against tank compositions
Good AoE damage overall
Loses penetration if enemy has more attack than her
Too niche
Pay to win unit
Mami Tomoe (Golden Ribbon) is a 5 stars Assault character in Artery Gear.
Mami is the pay to win character that requires you to spend crystals or real money to get. If you have spent a set amount of crystals, you are able to unlock her.
For global launch players, you should be able to get her after spending 16,200 crystals. However, to max her out (5 extra copies) and actually max skill her (using her special skill chips), you are going to need 72,000 crystals spent.
Her primary usage is in PvP where she can penetrate tanks since she penetrates defense based on the difference between the enemy's attack and her own. If her attack is higher, it will scale the defense penetration.
While she is good, she pales in comparison to Madoka as she is used every where outside of PvP due to her universal 85% ignore defense (if unique equipment is maxed). This makes her more of a one trick pony. She can still do well in PvE content though, so it is not all bad as she is a Crystal unit, which in my opinion is the weakest element of the 3.
