Let me give you my brutal honest opinion about the current novice state of kabbalist.
There’s a lot of PDocs running in Klai and only 2 people are kabbalist. This proves that the current skills of novice kabbalist is underwhelming and does not attract aspiring clerics. I’m no expert with PDOcs but the fact that they posses the ability to null every negative ailment from rank 1 to rank 3 is so good. Plus the fact that incinerate’s power relies on the number of ailment you inflict on the enemy is a good indicator how this class attracts cleric.
Now what can kabbalist offer? Ein Sof? It’s good, especially the SP restore. RS is fine, though I have no intention on investing a point in here. Merkabah, is strong, but takes time and if the enemy is smart, it’s gonna rush to and destroy all of them. One good thing about Merkabah is its range and probably wide AOE.
Now we have the math skill and reduce level. This is probably a reason why clerics never bothered with them in the first place. No one knows why they use math to pound enemy. It’s not a support skill or offensive or even defensive skill. What does it do? Compare the last 3 skills of PDocs and you’ll know investing a point at least is useful compared to the math skill.
Go to the public build in tosbase and find every kabbalist build. What I notice is that every kabbal build has 3 primary skills. RS, Merkabah and Ein Sof. That is a common skill build. No one bothered with reduce level and such since it’s useless and not a lot of kabbal in kTOS even bothered toying with it.
Until now.
So, yeah PDocs…“currently” shines a lot. I’m waiting to become adept kabbalist and that is where I’m going fully utilize math and reduce level.
