Diplomacy – it’s hard to figure out, even in the Physics Department, it’s not fully covered.

Come on..., this is actually discussed in detail in the Physics Department.

You turn on Vision, you look: these will attack, these too... Bam! 20 Spectral Dragons join for free.

Not all monsters have the setting: "never join" ;)

I am forced to issue a verbal warning for now!
Advice: correct all the obscene language addressed to anyone in your messages and finally start at least talking, instead of creating the impression of a conversation with swearing and insults. It doesn't matter who started... Otherwise, you are violating the rules of heroesworld, which in itself is punishable by a private message..., which is also at least very unsightly.

Sincerely.
