So a friend of mine for an upcoming campaign was going to be a rogue, specifically arcane trickster. However, he has changed his mind and now is going to be assassin and cross class to wizard.
That's fine with me, my problem is that he wants a special allowance to still have the unique arcane trickster mage hand, which will give him more abilities for no reason in my opinion.
He says it's balanced and there's no lore reason why not. I've argued saying it makes the unique nature of arcane trickster less valued.
Is it unbalanced to allow an Assassin to adopt Mage Hand Legerdemain?
