With more and more new traits being released recently, it led me to think of some of my own. Sure, some of these are outlandish, but I like to add a strategic element to a fight.

Bullet - increases own speed by 20% for 1 turn when attacked by a slower monster
Spirit - immune to all control effects and does not use stamina (I know Carlos said Spirit is the same as Artefact, but still...)
Greenfinger - immune to quicksand, burn, and poison
Spectacle - immune to blind, total blind, and stun
Suicide - may immediately kill the monster who kills him (unless they are immune to instant death)

Bullet would be extremely OP for deny monsters, but I think every other trait would be good.

I would think of a different name for the Suicide trait, because of the stigma surrounding it

Chameleon - the monster will have the same trait as the monster that is attacking him

@Francisco-Franceschi Good idea, but for how many moves?

@Clackers just the move on he is being attacked, it changes every time the monster is attacked.

Counter - 5% (or bigger) chance of countering the opponents attack, negating it (or reflecting it).

(Super Dan originally had something like this)

Occultist: Ignores every precision change.
Basically, if an enemy applies you daze, you will only have 25 % less damage, it will not reduce your precision.
Like an advanced "Immunity to blind".

@Edwin-Torres Confusion (possession) does not lower your accuracy. I think you meant Daze (25% less power and accuracy).

@keki14 yeah I fixed that, thank.

Doppelganger - your monster(s) replicates the exact state of the monster who attacked you, for 2 turns. [this would be incredible, as it could render other traits useless]

Eskimo - immune to freeze, mega freeze, and stamina leakage

"Fair revenge" if the monster is being attacked by a monster that was obtained during the clover chests bug fiasco, the attacking monster inmediately dies.

Armor - if getting hitted by an aoe skill , there is a 25% of missing
Vampire - immue to insta death and nightmare and possession
Bomber - 5% of killing instantly if getting hitted
Traveller ( time travel) - immue to time stop and cooldown activation

Is there a list of existing traits anywhere, like on the Wiki?

@Clackers
I think these are all of the traits

If attacked by any status effect it will miss and mirror back (super artifact).

Let's all laugh at Energized and Attuned. :D

Why are they even still in the game?

true :D, but i guess evolution, like how lagerchaun with time beeing is now monsters like Alpha cliviast shork or psilotus.

@Clackers said in New Traits - suggestions:

They said they were going to buff them, haven't seen it happen yet.
