Actually tried to make a build around abyssal echoes. Found some threads around the forum but no real bug report.
There are nodes that don’t seem to work:
Sequel of Decay: Should make the debuff stack - I can’t notice any damaage increase of the dot when spamming Abyssal Echoes. Obviously does not work. I saw a thread saying the skill is very nice when stacking the debuff. Wonder if it worked back in the days (summer '19)
Abyssal Form: Should increase Mana and Healt regen for 4 Seconds - I can’t notice any difference in regen after killing enemies with Abyssal Echoes. Also I would expect a buff symbol as well as some visual effects on my Charakter. Abyssal Form should have a cool change of the appearance of my char.
I’ve tested these nodes now. I found that Sequel of Decay is stacking, but it’s actually reducing the damage they take by mistake. Abyssal Form is working (I looked at my character sheet), though you have to get the final blow with Abyssal Echoes. If they die from damage over time or otherwise it won’t count.
Ok, so the Sequel Of Decay node is not working right now because it decreases damage when stacking.
Abyssal Form seems to work. As you stated the stats screen says I entered Abyssal Form becaus numbers of regen increases. Sorry for this. Can we expect a visual effect on the char e.g. covered in violet smoke or something? Also shouldn’t there be a buff symbol above the action bar?
There should at least be a buff icon, I agree. I don’t think a visual is planned, but I agree that the name “Abyssal Form” makes it seem like there should be, so it may make the most sense to rename the effect.
- thanks for your response
