Spellslinger doesnt trigger any spell

After obtaining the wand with the "spellslinger" ability, I transferred the "living bomb" spell into it, and it just disappeared. Now the bar fills up, but no spell activates. I tried different spells, different wands, unequipped items, relogged, etc.

same issue spellsinger don't work for me....
Erengy increases to 100% but the soketed spell is never cast

i do have the same issue. it stays at 100% and doesnt trigger any spell. is this buggy or do i something wrong?

Spellsinger is an "Invocation" skill, and do not auto trigger spells.
Yuo have to activate manually once enough energy is gained.

I do not know if it is normal that the invoked spell consume mana AND charges AND life (since I'm a Bloodmage).

Since Spellsinger invocation skill cast multiple copies of the socketed spell if I have enough charge, when I use the invocation my mana drain drastically (ten copies of Snap are casted simultaneously!!)

Invoked spells are supposed to be free of mana cost?
