tldr 5e „Awakened” Mind should be introduced instead of homebrew „Mortal Remainder” and should grant a 1st level Command-esque bonus action (using Charisma).
My proposed BG3 complacent description:
„Starting at 1st level, your alien knowledge gives you the ability to touch the minds of other creatures. You can command any creature to flee, move closer, freeze, drop to the ground or drop their weapon within 30 feet of you”.
BONUS ACTION
For starters, Awakened Mind would translate as a bonus action akin to lvl 1 Command (range 9m/30ft, targets 1 creature, 1 turn duration) but using Charisma. Thus available options would be the selfsame „Halt”, „Drop” (item), „Grovel” (go prone), „Flee” or „Approach”.
Calculation on Ability Check: roll 1d20+ CHA (score):
Bonus Action: Awakened Mind: Flee
Our Character is a lvl 2 Goolock, 16 CHA(+3). Is hidden (adv.). Rolled 6 and 4, must pick 6. Thus 6 + 3 = 9
Calculation on Saving Throw: roll 1d20 + CHA (score):
Enemy: is a rat, 1 CHA(-5). Is prone (disadv.). Rolled 19 and 10, must pick 10. Thus 10 + -5 = 5
That gives 9 vs 5, rat fails a save and flees from us (on their next turn and does nothing else)
DIALOGUE
AW should be used as handcrafted interesting dialogue option for some NPCs, let’s say [Awakened Mind] [Deception] could allow one to masquarade as the zealot NPC’s Deity or/and e.g. a Devil.
Combining Awakened Mind feat [passive] + Detect Thoughts would also count as a makeshift Telepathy (for all creatures) or Speak with Animals (for beasts).
After all, you are speaking with any creature in their native language. Command eg. in BG3 also works on animals and undead, in defiance of 5e, and is based upon identical principles as AM.
What gives?
-It’s easy to implement and continues the spirit of OG AM.
-Can synergize well with other GOOlock and Goolock adjacent features (like Speak with Animals, Detect Thoughts, Deception and co.)
-Opens new avenues to storytell, allowing further immersion and flavour
