Magic Weapon doesn’t have an effect on Shadow Blade, which becomes a central a part of your fight repertoire. Similarly, Elemental Weapon isn’t very helpful when you’re only making one assault per turn. Mark of Passage: Perfect potential rating increases, and the spellcasting adds a ton of useful choices for the Arcane Trickster, rogue 5e who typically has very little entry to teleportation.
WoodSCAG: Fleet of foot is good for moving into melee a bit sooner, however the opposite options will not do a lot for you. VanillaPHB: You will get all of the abilities you should be a Face out of your class and background expertise, however two extra are great so you can too get Athletics or one thing.
Raw unarmed strike isn’t a finesse weapon. In case your DM is willing to provide you with a home rule, it could be price contemplating. But Monk desperately wants more Ki points to be helpful, it potentially introduces MAD into your construct, and the Monk’s class abilities are typically duplicative with the Rogues.
