Warrior/Knight Help I Kinda Need A Better Build I Think.

Well, my build is, probably terrible.
I'm not sure if it's my gear or my skill distrubution, or just the difficulty increase, but I feel very underpowered compared to the pre gavel days.
I'm going with a fire/air build, but I still take loads of damage, whilst it's supposed to be the tankiest there is.
I still want to go with a tank build, but I also need a decent damage output, or else I won't be able to out-dps bosses.


My skillpoints and defence:

My helmet is Iodide, my chestplate Adamantite, my leggings Crystal, and my boots Passas Lux.
My weapon is bob's mythic spear, so there's nothing wrong with that.
If you got any good fire/air builds, please tell me.

 

Here's a tip: Don't use adamantite. It gives you a ton of health, but it destroys your element capabilities. (Switch it out with Andesite Aegis when you get to 77)

Oh, and for the others:
The Forgery or Blue Mask for helm
Kelight's Shield or crystal for pants
Passus Lux? Idk for boots
garnet ring, and 3 jester items

 

Thanks, that oughta be useful.
