I literally just did this not 5 seconds before you posted this.
This new guild quest literally f - - - s the mod.
The mod will work in guild quest, but if you go in and one shot everything right from the get-go...I guarentee you will get banned.
So activating the mod mid-fight means everything will die in one hit, including enemies and your units.
This means you have to time it so perfectly that you yourself get hit by NOTHING, while hitting every enemy unit on the map.
Trying to hit an entire mob + the boss themselves without them hitting you?
Now let's assume you somehow manage to do all that...would Klab's system red flag your account and proceed with a ban or no?
who knows.
point being: the risk to using it in guild quest has increased so substantially at the current moment that risking it doesn't seem worth the stress.
Use the mod everywhere else: do guild quest legit though.
