Ahhh crap I wanted to create an Arcane Trickster (4) / Illusionist (8) for some (crowd) control, but read the following report:
Mage Hand Legerdemain Useless + CHA instead INT spellcasting ability

It seems that Larian has ruined the Arcane Trickster as an INT subclass or for INT based multiclasses. Sure I could try a CHA based Archfey Trickster.... I don't know, like one doesn't have enough CHA based multiclass options.... I guess a dip for CHA based Mage Hand Legerdemain would be ok. But that's the second problem. The cantrip is not better than its "normal" form. So I guess a 3-4 Wizard level drop for an invisible Mage hand isn't worth it? Or does anyone have better to report?
