Tried my hand at doing an intro for Kali. Would like to also do one for Ceres. Let me know what you think.
[ Goddess of Secrets, Kali ] [ Shining Goddess of Secrets, Kali ]
In Hinduism, Kali is known as the Goddess of Time, Change, and Destruction. While her physical appearance in Puzzle & Dragons may not look anything like the Kali of lore, she does live up to her name by providing you Time to move your orbs, the ability to Change the board in sticky situations, and the raw power to absolutely Destroy anything that gets in your way. If you're one of the lucky people to have this girl in your box, consider yourself lucky because she's a very valuable asset to have, either as a leader or a sub.
In Puzzle & Dragons Kali comes in two variations, Goddess of Secrets - The Light Variation, and the rarer version, Goddess of Power - The Dark Variation. While both are arguably amongst the best leaders in the game (and are arguably the two best subs in the game for combo teams), this guide will focus primiarily on the Light version of Kali.
Active Skill: Five Colored Alchemy - Change all orbs to Fire, Water & Wood & Light & Dark orbs.
Leader Skill: Palm of the Four Origins - ATK x5 when attacking with Fire, Water, Light & Dark orb types at the same time.
Ultimate Evolution Leader Skill: Six Flower Palm of the Four Origins - ATK x5 when attacking with Fire, Water, Light & Dark orb types at the same time. All attribute cards ATK x1.2 when reaching 6 combos or above.
Simply put, you should play Kali if you want a good combination of Power with ease of use. She is considered one of the "4 Color Match" leaders along side Sakuya, Durga, and the twins Umisachi & Yamasachi. These leaders give an incredible amount of power for a minimum of 4 matches, something every player trying to do end game content should be able to do. While not nearly as hard to play as Anubis, these leaders will be somewhat challenging for newer players to get used to. I strongly suggest looking up some orb manipulation tutorials such as the ones featured on TylerPAD's Youtube Channel and practicing them in Endless Corridor. If this is still difficult or something you don't enjoy, Kali (or any of the 4 Color Match Leads) may not be for you.
So Why Kali vs other 4x Leaders? (Comparing Ultimate Evolutions currently out in the North America)
For Reference:
36x Damage is possible. This extra damage can lead to killing things in 1 hit as opposed to 2 like many other 25x leaders.
Two Awokens means it is possible for your lead Kali to hit for 81x damage by herself.
2 Skill Boosts + Kali's low active skill cooldown means your teams actives are up faster
Five Color Alchemy insures that no matter what, you will always be able to activate your leaderskill when you choose. Jammers, Poison Orbs, or missing certain orb colors cannot stop her.
2nd Highest Health, giving her a little bit more survivability.
Healer type gives access to certain key burst options as well as giving her very high RCV to recover when your health is low.
Lacks a natural burst option like Sakuya's Boisterous Dance and Durga's Divine Instrument Strike to easily burst down bosses without requiring key subs.
Five Color Alchemy guarantees a leaderskill activation but it doesn't guarantee a board with a lot of light orbs to guarantee a good burst, like Umisachi & Yamasachi's Ritual of the Mountain and Sea.
Semi-rigid sub pool. Kali only has a handful of very good options for subs compared to say Sakuya. Kali's strength is her consistency and power vs. the other leaders. If you can't maintain two prongs, 6+ combos, or Five Color Alchemy every turn, you'll gradually do equal or less damage than all the other 4 Color Match leads.
