Help with castsequence and [known] macro

[Noihara-kazzak]

I’m trying to create a macro that’ll first cast, Phantom Singularity followed by Soul Rot, then Malevolence.
And with a reset of 30 sec and showtooltip for each spell.
After several tries from info I’ve found on the forum, I’ve gotten 2 of the spells working, but for some reason I can’t get the last one to stick without it breaking.
I’d like to use [known] so that I can use the same macro for Hellcaller and Soul Harvester build.
This is what I’ve cooked up so far:

#showtooltip [known: 205179] Phantom Singularity; [known: 386997] Soul Rot; [known: 442726] Malevolence
/castsequence reset=30 [known:205179] Phantom Singularity; [known: 386997] Soul Rot; [known: 442726] Malevolence

The reset is for the entire sequence and timed ones count from the most recent press (regardless of whether or not that press cast a spell).

You also can’t do options for each spell in the sequence, they’re done for the sequence as a whole.

/castsequence [options] reset=condition1/... action1, action2, ...

So the most basic version of your desired sequence would be

#showtooltip
/castsequence [known:205179,known:386997,known:442726] reset=30 Phantom Singularity, Soul Rot, Malevolence
