Is boss a monster?

I read form poe 1 that boss also a monster.But i see trial of sekhema relic have a mod that 'Monsters take #% increased Damage' and 'Bosses take #% increased Damage'. So in poe 2, Is boss a monster?. If that is, the 'Bosses take #% increased Damage' feel dump

Yes because it's dump, the process is dumb clear.

If you have both relics,

Is "monster" ?
Yes
Is "boss" ?
No

It's monster but not boss (could be something else like "normal", "magic" or "rare". it only matters when such mods exist on relics.)

-> only the mod with "monster" tag takes effect.

Is "monster" ?
Yes
Is "boss" ?
Yes

It's monster and boss.

-> Both relics work.

Is "monster" ?
No
Is "boss" ?
No

-> Neither should work. in the first place when it doesn't work, we don't care if it's monster, boss, w/e or not.

Is "monster" ?
No
Is "boss" ?
Yes

-> It cannot be if "boss is also a monster" is true. If it's not true in one way but can be true in the other way, it's whole different story. I mean there should be another rule. if it doesn't exist, it doesn't work at all.

It's so-called "logical operation".

Edit
There can be "true" or "false" in a boolean type basically and all other exceptions are "null", which is like "i don't know" "wtf???" "it's so dump!!!". it's actually really dumb logic but works somehow.
