Old Daka zeta ability is NOT stacking health :(

Old Daka gains Max Health, which means her total health pool will increase, but the percentage of health will remain the same. You will most likely not see a change in her health bar, but she did in fact gain health.

Hi FeltZ_CG, thank you for your answer, but I don't believe this is the case. Asajj gains 5% max health, which is the same type of health increase as Daka, but she is obviously gaining way more health. It seems like Daka's is not changing at all. This is especially obvious in the raids, because Talia's heal on basic barely affects Asajj's health bar, while it almost completely heals Daka. This makes no sense since Daka is supposed to be stacking twice as much health as Asajj per revive.

I'm quite upset about this since the only reason I spent the zeta on Daka was for the extra durability in raids (under a Talzin lead, letting Talia die) and it does not seem to be working. I know of others who have also been experiencing the same issue. Is there somewhere I could send recorded gameplay as proof?

@FeltZ_CG I too am having this problem. As described by @ro-ju-la in his reply, we are not going by the "appearance" of Old Daka's health bar which we understand is merely a visual representation that is not "drawn to scale". The proof of this issue is evidenced from several quantitative factors including:

1. Talia's heal from basic ability (Draining Strike) healing Old Daka significantly, whereas Asajj's health is barely moved; and
2. AAT's enraged hits taking off only about 15% of Asajj's health, whereas it takes off about 90% of Old Daka's health.

The only test that I have not yet formally conducted is performing a heal using Old Daka's Chant of Resurrection. With a 4 turn cooldown, and assuming:

• A squad of 5 Nightsisters of which 2 are dead and 3 are alive (of which Daka is one of the 3 who are alive)
• Only basic abilities are used and therefore one of the 2 dead Nightsister is revived during each turn of each of the 3 remaining Nightsisters during the 4 turn cooldown

Then Old Daka's health should increase by (3 Nightsister basic abilities per turn x 4 turn cooldown = 12 revives) 120% and therefore her heals should also be increasing by 120% from heal to heal to heal.

As mentioned above, I have not yet formally tested this, but I am pretty sure that a 120% increase from heal to heal to heal would be fairly noticeable. My Old Daka has 23k health. Her first heal should therefore do 11.5k, second heal 4 turns later should do 11.5 x 120% = 25.3k, and her third heal should do 55.6k, and her fourth heal should do 122.3k, etc. I cannot say with absolute certainty, but it would have been quite likely that I would have noticed "122,320" in big green numbers popping up if her zeta ability was working correctly.

Thank you for your continued support.

The best way to see that this is working, is to use Talia's "Water of Life" special at max tier. It will heal for 50% of the Nightsisters life.

Use her heal in a battle to get an exact amount of health, then try after a few nightsisters have died to see the 10% Max Health increases.

Hi @FeltZ_CG, thank you for your suggestion. I have just tried it out and it confirmed my suspicions - Daka's zeta is indeed not working. I entered a battle with the following squad:
Mother Talzin (both zetas)
Asajj Ventress (unique zeta) -- starting health 20,846

Old Daka (unique zeta) -- starting health 24,954
Talia (all omegas)
Nightsister Spirit (level 1, three stars)

My nightsister spirit died immediately. I was then able to revive her 5 times using basic attacks, as per Mother Talzin's leadership zeta. I also defeated one enemy in the process. This means that Asajj should have received a 5% max health stack 7 times. And indeed, when I used Talia's "Water of Life," Asajj recovered 14,071 health.

Meanwhile, Daka's unique should have been triggered 5 times for each time nightsister spirit was revived, but when I used Talia's "Water of Life," she only recovered 12,477 health.

I have recorded gameplay of the above description and also have a screenshot. I believe this proves conclusively that Daka's zeta ability is not working. Please let me know if you can reproduce this on your end. This has been very irritating, as I've had the zeta for over a week now and it has been useless.

Just a guess, are the resurrections done by Talzin’s zeta not classified as actual resurrections? This would also explain why Hoda does not gain 100% TM bonus every time this occurs also. 

Are there any characters that are benefiting from this resurrect? Are there any we can test?

Yes, Asajj benefits from them. Also, Daka gains 50% TM and lowers her cooldown of Chant of Resurrection as intended. She's just not stacking health, which is the whole point of the zeta.

Right now, only certain resurrections are giving daka's zeta the health stacks (zombie resurrection seems to work fine). For a little more data, feel free to check out the bug report I submitted not too long ago. Daka's health stacks seem to struggle most when there are multiple revives or attacks per turn like with acolyte and talzin.
