Another Cast When Damage Taken question

i've got a lvl 4 CWDT linked to a lvl 2 Molten Shell, a level 5 Decoy Totem and a level 3 Searing Bond. The MS triggers just fine, but the other two don't trigger at all. What am I missing here?

Both, decoy totem and searing bond are totems.

They're totems, yes, but they are not "skills used by totems". I'm pretty sure those are 2 different things.

Using CWDT with Decoy Totem is used on quite a few popular builds.

That sounds more like builds finding a place to put Decoy Totem that doesn't detract from the number of supports they can put on their other skills.

Regarding the actual question, read Decoy Totem and Searing Totem:
"Summons a Totem which uses this Skill"

How old are these builds ?

CWDT and Decoy totem

Looks like totems stopped being spells nearly a decade ago, with the release of 2.0 ?

And throwing mines isn't casting (any more ??).

Now, with traps it's a bit confusing because they (all?) have also the Spell tag, and are affected by spellcasting speed, but :

"

Traps and mines (and totems) will not work with "Cast on..." trigger gems, even if the trap/mine has a "Spell" type gem tag/keyword; the player places or throws the trap/mine, but the trap/mine is doing the actual spell-casting.

I see my problem now. I misread a sentence in the notes of the build and thought that the CWDT was triggering the Decoy Totem as well as the MS.

Thank you for the help! I wouldn't have noticed my idiocy without it :)
