Support for Cast when Damage

Just curious. Does Support gems work for the spells when cast by Cast when Damage Taken?

Say I have Reap at lvl 56 and Brutality at lvl 56. When CwDT happens, does my Reap get brutality support? I am asking this because it seems like it's better to just put more Active spells like Reap, Spell Blade, etc.

I know that Spell Echo does not work with CsDt right?


While we are on this subject, I just want to confirm that if I link Cast When Damage with Reap in "2 different equipment", both Reap can get triggered at the same time right? Or needs to be different level of Cwdt to trigger both with different life loss threshold?

You should read the wiki page for Cast When Damage Taken. It answers your questions in detail.

Yes, you can support triggered spell gems with (some) support gems.

No, Spell Echo does not support triggered skills.

No, multiple copies of the same spell will not be triggered at the same time.
