Platinum!

Platinum! is an achievement/trophy in the first Bayonetta game that is unlocked by getting 10 Platinum medals in 10 different battles.

Description
"Earn 10 Platinum Medals. Must be earned in 10 different battles."

Guide
To earn a Platinum Medal you need good scores in the three Combat Ratings. That means you will need to be quick, take little to no damage and have a really high combo score.

For the combo score:

To earn a high combo shoot with Scarborough Fair at enemies that are too far away then close in. If you Taunt enemies ( or ) you can increase your attack value but be careful, when you do they are more aggressive and attack faster.

For timing you need to remember that a Verse only truly begins with a battle and usually ends afterwards, sometimes you'll have to move forward for another fight. So keep your battles quick.

For damage you will either need to master dodging (plus Witch Time), using the Moon of Mahaa-Kalaa or simply picking off the enemy before they reach you. Your best bet is to just go for Pure Platinum, take no damage whatsoever, if you get hit 1-3 times then its possible you will simply get Gold instead of Platinum or Pure Platinum.
