can Fearless Cleave friendly fire?

[dragonus]

My dwarf wyrmic was in Halfling ruin with Subject Z and Yeek Wayist. Due to the past couple runs with Rogue and Solipsist, I had all friendly fired the Yeek, I restricted myself this time of using any AoE talents. I didn't consider fearless cleave as a AoE attack (or maybe it is?), and I have used fearless cleave a couple times when Subject Z and Yeek Wayist were standing next to each other, it was ok at first (every turn I checked the Yeek's personal relation was neutral) until the third time, the Yeek was hit by the fearless cleave and turn hostile

I have been frustrated by friendly firing several key NPCs in the past several runs, and very weird that wasn't a problem in my earlier runs. I play the game offline, so I suspect it could be bugs causing by code jamming after played the game on the same computer for couple hundred hours? ( I'm no expert in computer though)

And I wonder if someone could provide a general guide or analysis of friendly fire (or if there is a post in the forum on this topic already, please send me a link):
- If an NPC has both their faction and personal relation show as friendly or neutral, can they be friendly fired? If yes, what kind of attack can harm them?
- The main concern is NPCs like the escort, the rich merchant and the yeek wayist. In theory if they are not hostile, you cannot attack them, bumping into them will just switch place, correct? Like the blood master after you played the ring of blood fight, or the sandworm tunnelers, or even all the town folks, you just can't attack them.
- For the same token, can NPCs friendly fire the player? cos' I remember in one recent run, the yeek turn hostile after he friendly fired me, and got a fire damage from my spike armour. I literally pulled my hair off for that!
- I know some talents were described as safe on summons, but are they also safe on NPCs? In my last Solipsist run, I one shot an escortee with Mind Sear, which is a talent completely safe on my thought-forms. Is there a guide on what talent safe on what kind of summon or NPC?

AFAIK:

- Yes, you can receive friendly fire damage, and yes it can kill you. Unsure whether it can proc thorns damage which then turns the ally hostile but I wouldn't be surprised.

- All AoE damage dealing talents, unless specifically stated to only affect enemies, will damage friendlies in the area. This does include Fearless Cleave, since it hits a 1x3 area in front of you.

- You cannot bump attack friendly actors without specifically right clicking them or holding CTRL + direction, you will just swap position otherwise (or talk to them in a couple special cases).

- Mind Sear is special cased to not interact with thoughtforms (the whole Psychic Assault tree is actually) and therefore would still hit all other actors, including escorts and other summons.

Thanks for the reply.
Regarding your third point on bumping attack, would it be possible that under a blind debuff, you can hit a friendly NPC by bumping into him?

I'm honestly not sure. I wouldn't think so, but Blind does interact somewhat strangely for some things.
