Psionic touch and staffs

[Mook]

After picking up some nice items I have started a staff mage in tandem with my warrior. I am mainly following Dream tree at the moment,and have maxed psionic touch. It works well with my Staff of Magi + Prometheus, or any stick I've picked up, but does not respond to my Necromancers staff+Zesus. Magi has fire+burn damage, Necromancer has (mucn more) lightening damage +electrical burn (+50% against undead). Is there a factor I'm overlooking?
Another question, is elemental and other non physical damage affected by the foe's armour, ie is Ravages of Time (spirit) any use for this build?

What do you mean, it doesn't respond?

@Mook What do you mean by "does not respond to my Necromancer staff + Zeus"?
It's doesn't get benefit from Psionic Touch when  the charge hits lands, it's not pass through target or so?
- Only Physical dmg works against armor, Ravages of Time reduced enemies armor absorption so your physical dmg attacks will deal more dmg, but not too much, about some hundred dmg at best.

Armor, right I thought that was the case, wanted to double check.
Psionic touch wasn’t starting up when I switched to the Necromancers staff, and the same again when I used a blue staff. I think I’ve figured it out. They were in the 2nd (alternative) weapon slots. When I took the Mages and the Blue both out of the slots and switched them around, The Blue (slots 1) worked fine, the Mages (slots2) not.
I’m using iOS version, I don’t know if that is significant.

You need to assign Psionic Touch to both buttons so it can work with both staves.

Maybe you need to set that skill for that weapon swap.

Thanks. Yes, that’s what was needed.
