Chronomancer Temporal Rift cannot be lifetapped bug

When using archmage temporal rift gains a mana cost, but I wasn't able to counteract it with lifetap support - despite lifetap stating "support any skill", it cannot be socketed into temporal rift. This effectively makes temporal rift a lot worse for archmage chronomancers.

Came to post this as well. Either it shouldn't get a mana cost from archmage since it's not a damaging skill or we should be able to support it with lifetap.

playing mind of matter archmage is brutal at the moment.

yep. this is very unfortunate
