I chose Drow as my race and I am happy to report that being a Drow in BG3 seems to matter. I got different behavior from different NPC. The goblins were friendly to me. I hope this continues through the whole game.
For companions I used Lae’zel and Astarion as they are the most evil of the ones we have. Added Shadowheart because she sometimes approves of various bad actions.
Wyll is out because he wants to kill Goblins. Gail just isn't giving me any evil vibes.
I honestly don’t think any of the companions are evil though.
Overall there are many options to do evil like actions but they are more being a dick then true evil.
Prolog
1. Cripple Us
2. Kill the two thralls in the room with Shadowheart.
3. Do not help Shadowheart, after you see she is trapped.
4. Do not help the Dazed Women in the pod in another room.
Chapter 1
1. Shadowheart chides me for leaving her to die, still joins me.
2. First talk with Astarion there are no options to agree with him about learning to control the tadpole to gain more power.
3. Kill trapped Mindflayer from abush they rob the 3 sailors, killing them.
4. First Long rest, use the Drow option as seems most evil to give into your pain.
5. Attack Gimblebock, Taman, Quelenna & Warryn from ambush.
6. Attack the Tieflings to free Laz’eal with even talking to them.
7. When back to the first ruins, killed everyone there, why are those people hostile?
8. Attack Andrick & Brynna from stealth, killing then after combat. I had my Imp slay Edowin, the unconscious guy on the ground. After combat, still get the tadpole exiting him and I let it go, hopefully it will find another host or become a Neothelid.
Goblins
1. Blighted Village rooftop goblins see that we are a Drow and do not attack.
2. Goblins at Windmill recognize I am a Drow but still get to use the tadpole to dominate them. I use the windmill to fling the deep gnome to his death.
Other
1. Interrupting the couple in the barn, seems being Drow has no effect on them, kill them.
2. Recruit the Orges.
3. Guess Gnolls don’t care if I am an Evil Drow, they are always hostile
4. Meet Karlach, take out her assassination contract on the cultist. Ambush them and report back to her.
5. Exhort money from Rugan to save him from the Gnolls, try to rob him after, find out he is with Zhentarim. Convince him to con his bosses, tell them the chest was stolen and we’ll split the money to sell the chest. Got password for Zhentarim password for when we get to BG.
So the main evil plot of chapter 1 is will you side with the Goblins or the Grove? Overall I feel this is fine, my only issue I have is that you do not seem to have an option to go meet Minthara first and then go to the grove.
I have no idea how to adjust it because before we go to the grove, no idea where it is so it not like Minthara can send Goblins to the grove to attack it so we can then play hero to befriend them so we can betray them. Wait, Minthara should know where the grove is, are you telling me that not one goblin when that party found the grove so we could help out at the gate was not sent back to report to Minthara? I guess it could happen that way but seems like poor writing.
Goblin Camp
1. no evil interactions with Volvo?
2. Find Minthara, agree to go back to Druid Grove to Betray Them.
3. Did not interact with other goblin bosses as I wanted to get the betraying the grove out of way first.
Druid Grove Betrayal
1. After fighting the Goblins at Druid’s Grove, Shadowheart states we should just find a healer and move on, this is not our problem. Took the option to agree with her.
2. You can talk to Zelvor without asking for a healer and do have an option to demand a reward to help them. (Decided to not have the tadpole removed, going for unlimited power!)
3. Tell the 3 Tieflings to run away and not help defend the Grove.
4. Talk to Wyll, using the Tadpole on him, never promising that I will kill the Goblin Leaders.
5. Talk to Asharak, tell the kids to soak the fields with blood and embrace death.
6. Talk to Kagha, keep silent, letting the snake kill the child. Tell her she should have just killed the child. Tell her you are not interested in helping the refugees.
7. Ignored Nettie, the only option seems to be to ask for healing.
8. Macroryl seems like a villain, no conversation for him?
9. Talk to Zelvor, let him hire me to assassinate Kagha.
10. Assassinated Kagha and all the other Druids in the inner room.
11. Tiefling killed other Druids, you lose access to any vendors here.
12. Final betray Tieflings at Druid Grove. None of the goblins will go inside, so why do I open the gates? Also what are Rath and Silver alive back in the Grove, they were killed earlier? Thought all the Druids are dead?
13. Ok, now I have to go through all the grove in turn based mode to get to the back and kill Silver & Rath a 2nd time.
14. I see Wyll body among the slain. If I go back to camp, no Wyll, good job! Shame to lose a companion but that would fit Wyll’s story so I approve!
15. Where is Minthara? OK, she in the room Zelkor liked to use, kill the last Tieflings with her.
16. Talk to Minthara, she screams at me “There are more. Hunt then Down!†All the Druids and Tieflings are dead, what is she talking about?
17. Go double check, no, nothing else to kill.
18. Back to Minthara and see still demanding I kill more stuff so guess my evil play through is done.
Overall I think that an evil playthrough is possible but still needs more work.
