Crazy Diamond Is a Close Range Stand With Long Range and Support options, This stand is heavily underrated because of how often you roll this is normal arrows often with quotes such as "SPTW without a Timestop" But these really undersell Crazy Diamond which I will explain now
Crazy Diamond has two passive abilities "Vengeance" and "Stand Mastery"
Vengeance Works like this : Every % of your max health you lose, you deal an extra 0.02x damage. The cap is 2.75x damage. This can be a saving grace in 1v1s and more, since when your low normally you have to worry about getting enough damage in, with crazy diamond you wont need to worry since you can rush in with a barrage and get them to red health in 3~ seconds. While Stand Mastery Allows you to use a move while not having your stand summoned this allows you do stay alert while not having your stand summoned. Or turn off your stand to taunt people then when they are close attack them, the only moves excluded from this are Left Mouse, Stand Jump, and Heal Toggle.
E - Stand Barrage, A Mediocre Barrage at first but if you use it at the right time it can be one of the deadliest in-game as this gets buffed by Passive A aswell
R - Heavy Finisher, this is a very strong Heavy Move which can cap out at 72.1875 damage which is most likely the strongest heavy attack and is most likely going to be your most used move
T - Bearing Shot, This is Likely Going to be one of your least used moves if you are good with crazy diamond, as the Heal Toggled Version of this is far superior with control and cooldown
T(In Healing) - Glass Shard, A Very Good Version of Bearing Shot which can be controlled by turning to make the shard turn (Note: The Trail will either be Yellow or Red, The Trail does not effect anything as far as I am aware)
Y - Return Punch, This is likely going to be your 2nd most used move due to how useful it is, you can use this move to fish off a heavy or use it to force your enemy away by jumping away from the return, not much to say but a very good move
Y(In Heal) - Wall Creation, This is one of the best defensive abilities as it can block projectiles and can slow players down, this is sadly disabled for now so don't use it unless you wanna get stunned.
F - Heal Toggle, Not much to say, Low Cooldown Gives a better bearing shot. Amazing for support Passive A will increase heal aswell.
X - Block, Crazy Diamond Holds its arms in an X position Guarding from attacks this blocks 75% of damage which is the same block as Star Platinum Over Heaven, Tusk Act 4, and other Evolved Stands.
Overall Crazy Diamond is an amazing stand with good moves and a Superb Block Closing this off, I Would suggest Crazy Diamond if you like to 1v1, Barrage Battle, Like doing Tournaments or just wanna have Fun as CD is one of the Funniest Stands to Play, Closing this off. Next time you get Crazy Diamond don't say "Ew" or "My luck sucks today" as Crazy Diamond is one of the best stands if you learn to use it.
I Always Use a stand before making an Underrated Stand Shoutout, which is why some weeks might take longer than others, I make sure to do things such as 1v1s and Barrage Battles to test a stand, I also read wiki pages and test things out with friends to see the limits of a stand, so don't call this "a biased Suggestion" as this is a review of underrated stands.
