The purpose of this guide is to show you how much ability expertise (proficiency with specific spells) you gain whilst in the Lost Grove.

First and foremost, each pet has up to 4 abilities (5 once level 75, but that's not reachable at this point).
Each of those has up to 4 "gains" in stars (up to 5 star), but are limited to 3 gains (4 stars achieved) at this time.
This affects both the effectiveness of the ability (in various ways), and how fast you gain expertise.


Rate of Gain:
From what I can tell, there are exactly two ways an ability gains expertise. (Both only work in Lost Grove)
- each time an ability is used
This could be less than .01%, and seems to be based on the level of the ability and which ability used, but does not seem to be based on the enemy.
- Every time an enemy is defeated
based on how difficult the enemy is, all abilities the pet has the capability of using (so not ability 5, at this time), will gain an amount of Expertise. It seems that this amount is a "Flat Amount" (based on level of enemy and level of ability, but not slot).

Post 2: Consolidated Charts

The Maws of Madness Update:
With the update of adding the Maws of Madness, which added tower floors that gave a certain amount of displayed Ability Expertise, we can compare notes.

Amount Required to Gain Rank
Current // Target. Points Required
1 --> 2: 2000 points = 100%
2 --> 3: 4000 points = 100%
3 --> 4: 8000 points = 100%
4 --> 5: 16000 points = 100% (15000-15555-16153)

Usage Score:
Ability 1: 10% of a point
Ability 2: 50% of a point
Ability 3: 30% of a point
Ability 4: 2 points
Ability 5: 5 points

Kill Score
2 Star Enemies: 50% of a point 60% with Artifact
3 Star Enemies: 2 points 2.4 with Artifact
4 Star Enemies: 5 points 6 with Artifact
5 Star Enemies: 30 points 36 with Artifact

At some point, numbers above were changed. They used to be 1/2/5/20
Artifact in question is "Artifact - Grand Protector's Insignia" rewarded from Patriotic Event 2021

Previous Information:

Assumptions:
1: Enemies with the same star amount give the same amount of kill-points. (all 4 stars give same as any other 4 star)
2: Behemoth Does not affect any of the below data.
3: Element of Pet does not affect any of below data.

I make these assumptions based on the data I have seen. But the odds of me not having noticed something are still not zero. If these is untrue, I wish to know.

Use Data
Ranges provided are to show you the margin of error associated with the data collected. Presumptions are based upon numbers that make sense, but are not guaranteed.
Ability 1
Target: 2 stars. "Points" necessary: 18750 - 20000 Probably 20k, which means 2 hits = .01%
Target: 3 stars. "Points" necessary: 37124 - 43333 Probably 40k, which means 4 hits = .01%
Target: 4 stars. "Points" necessary: 76800 - 83478 Probably 80k, which means 8 hits = .01%

Ability 2
Target: 2 stars. "Points" necessary: 3750 - 4000. Probably 4k, which means 1 hit = .025%
Target: 3 stars. "Points" necessary: 7142 - 8571. Probably 8k, which means 1 hit = .0125%
Target: 4 stars. "Points" necessary: 10322 - 21333. Probably 16k, which means 1 hit = .00625% (Thanks to Kaita)

Ability 3
Target: 2 stars. "Points" necessary: 6721 - 6949. 1 hit = .01439% - .014878%
Target: 3 stars. "Points" necessary: 11428 - 14166. 13.3k would mean 1 hit = .0075%
Target: 4 stars. "Points" necessary: 16000 - 26666. (Thanks to Painteventer & Kaita)

Ability 4
Target: 2 stars. "Points" necessary: 952 - 1052. Probably 1k. Which means 1 hit = .10%
Target: 3 stars. "Points" necessary: 1666 - 2500. Probably 2k. Which means 1 hit = .05% (Thanks to 18eities)
Target: 4 stars. "Points" necessary: 2666- 5714. Probably 4k. Which means 1 hit = .025% (Thanks to Kaita)

Kill Data
Affects all abilities based on how many stars are possessed already. Note, these are actually estimations, but since they are larger and harder to encounter "more than a few enemies", we have to live with it.
2 Star Enemies: .05% / .025% / .0125%
3 Star Enemies: .10% / .05% / .025% (S2: Thanks to 18eities (and myself, though 18 was first), S3:presumed)
4 Star Enemies: .25% / .125% / .06125% (S3: Thanks to Kaita)
5 Star Enemies: 1.00% / .50% / .25% (S3: Thanks to 18eities)
