Temporal Chains increasing mana cost (on Archmage)?

I have confirmed this on two Temporal Chains maps now. I am playing Stormweaver Archmage with Spark as my main skill. I don't know if there is some complicated interaction I'm missing here with Temporal Chains, but the result is that my mana cost increases by about 100% if not more. That, or my mana regen is dropping so much that it appears my mana cost is higher. Is Temporal Chains supposed to slow mana regen? It doesn't say so in the tooltip.

Also note, I have Arcane Surge + Arcane Surge effect from ascendancy, plus Arcane Surge nodes from passive tree. Perhaps Temporal Chains is instead interacting with Arcane Surge in some weird way.

Anyway, there's either some unintuitive but intended interaction here that I'm missing, or there is a bugged interaction happening.

i have encountered the same issue , me and my guild are pondering what it could be , cause if temp chains would affect mana regen , it would reduce your mana regen by the same amount by wich it reduces your cast speed , meaning your mana regen should feel exactly the same .

I have also encountered this. I went to a map with Temporal Chains and my mana regen was instantly busted. When I went to another map, it was fine again.

I guess Slow impacting "actions" could include Mana Regen but if that's the case it's very unclear. :thinking:

Also definitely had this occur hence searching and finding this thread.

i cant run out of mana with current stats, but with temp chains on was running dry all the time... they need to fix it or update description as to why.

I noticed the same thing. I suspect what is happening is that it is a bugged interaction between action speed slows and how mana is spent in PoE 2. In PoE 1 mana was spent all at once, whereas it is spent over the course of the cast in PoE 2. I'm guessing that the game calculates the correct rate of mana drain for the cost to be paid by the end of the cast, but if that cast gets slowed in any way it just drains at that rate but over a longer duration due to the slow, resulting in you paying more mana per cast.

Bump. Happening to me as well.

Bump!

Same for me.

Also noticed this happening to me

Same here.
