i just realized this
snarbolax is weak to piercing
jelly king is weak to shadow
twins are weak to elemental (is that right?)
vanaduke is weak to elemental.
any one else see what the most useful damage to choose is? i think that some thing should be done about this.

"the Snarbolax is weak to Piercing and resistant to Elemental attacks"

"Royal Jelly is weak to shadow attacks, and has resistance to piercing. "

It doesent say what are they weak to or resistant to but we can only assume they are construct type...

"Constructs resist piercing damage and are weak to elemental damage."
http://wiki.spiralknights.com/Lord_Vanaduke
"His body has a slight weakness to piercing, and is slightly resistant to everything else. His mask, however, is resistant to any damage type besides Normal."
Its been there on wikipedia for ages...
So it's evenly distributed.
4 bosses, one super strong and one for any other damage type.
One could say that since it goes from easy to hard it's not fair (you can defeat snarby with anything, T1 is simple), but shadow lairs fixed that.
Its all on wikipedia i think... Spiral wiki.
