How to kill Orin solo before she acquires Unstoppable and transform

[northernwater]

I did this on Tactician. Should work in honor mode.

Lvl 12 Rogue Assassin/Deep gnome/Urchin
Titanstring Bow (Elixir of Cloud Giant Strength)
Gloves of Archery
Shapshifters Boon Ring(make sure you shift)
Ring of Shadows (cast Pass with out a Trace)
Pick other gear to maximize crit chance and damage per hit - your mileage may very.

Have any capable caster cast Greater Invisibility on Rogue. They stay out of combat by the door. Use fly to get close enough for bow shot on Orin. Her first hit when she is yellow will heal after that they no longer heal.

Each attack will trigger an escalating Stealth Check from 15 - 23.
Your stealth checks should be max(10,(1d20,adv))+1d4(Shifter Ring)+10(Pass With out a Trace)+5(DEX)+8(Proficiency)

Have an invis potion ready and Alert just in case you fail your stealth check with a nat1. Also, she has AC 20 so make sure your Attack Rolls are buffed.

I confirmed this works in Honor Mode. The only difference is she teleports to your invisible location after each hit because of Murderous Retort. Still no unstoppable and no slayer form. She is in combat because she is a red character.

Here is an image showing the first and last stealth check.

I never claimed I discovered a secret.

I did mine intentionally avoiding multiclass because your Stealth Check rolls are better. Also, she picked a poor background and race for stealth checks. She does not show her Stealth rolls. She should have. That's the weakness of this technique. The DC increases with each attack. This happens on every attack. So increasing the number of attacks per turn or extending the duration of the invis allowing more attacks increasing the DC.

Her video style is unbearable so I did not watch every detail, but I noticed at 9:35 she rolled a nat1 on a stealth check and remained invisible. Hmmm ... I have found when I roll a nat1 or simply fail a stealth check you loose invisibility and enter combat.
