Is it possible to obtain props under the Pacifist rule? Like laser or B? Please give me a clear reply, thanks！

I'm interested in Pacifist and want to try it, but I don't know if it is allowed to get props.

I'm not a mod (or a runner of this game), but it would seem fine to me to use upgrades. The current run on pacifist is also a "low%" run which is why no upgrades were gotten. But by definition, pacifist just means killing only what you need to, not doing it with the least amount of weaponry.

Yes, I'm not sure if the rules here are the same as those of TAC's Pacifist, but no matter what rules I am willing to try, I just hope someone can explain it for me, I don't want to go the wrong way.

Normally I would say yes, but the Pacifist Rules specifically state:

Only bosses and unavoidable barriers are permitted to be destroyed.

I would assume this restriction includes powerups, just as a Runner. Hopefully a Mod will clear it up for everyone. :)
