Defense tips for countering league mechanic

Source: https://www.poewiki.net/wiki/The_Viridian_Wildwood#Wisps
Basically what wisps do beside damage reduction is empower all monsters in 3 ways depending on their color.

1)Blue wisps give more critical strike chance and additional critical strike multiplier

While we all want as much blue wisps as possible because they increase currency drops they are the most deadly ones. From my experience they will substantially increase crit chance and multi vs player that even one basic attack will one shot average characters. When combined with inc crit and multi from map mod or any damage mod it's almost guaranteed death trap of a map.
-General aid for this is upgraded Solaris pantheon to avoid being crit multiple times in a row.
-High evasion goes a long way vs crit attacks as it lowers the chance for monster to crit you
-Block and Spell block
-Spell Dodge
-Reduced damage taken from critical strikes

-Mistwalker ascendancy notable from Assassin gives crit immunity
-Brass Dome, gives crit immunity
-Covered in Frost applies on monster 50% LESS crit chance debuff

2)Yellow give increased attack, cast, and movement speed

To counter yellow wisps general rule of thumb is to reduce monster's actions as much as possible.
-Temp chains
-Chill
-Freeze
-One Step Ahead ascendancy notable from Trickster
-Stun
Maim, hinder...

3)Purple give additional projectiles and more area of effect

Purple is half and half as not every monster has projectiles or area damage. Inc Proj can also be very deadly because they shotgun and therefore can do multiplicative damage.
For this you can't do much apart from avoiding it. So Evasion, Dodge, Block and manual avoidance is recommended.
Solaris pantheon again can be of help here.

If i missed something please add it. Ofc high amounts of damage help greatly because the shorter the monster lives, lower the odds for it to kill you, but it won't be enough to survive mayhem in maps.
Hope this helps.
