For traps: exercise your Mario skills.
For enemy spells: grin and bear it.
My first main character was a rogue, so I got lazy with traps and just stood in them. On my arti, I was impressed with what I was able to accomplish when avoiding traps. Use any HP boosting spells/scrolls before taking on a trap, radiant forcefield is also very handy.
If your WF you have the advantage of inherently higher HP and quickened repairs/reconstructs.
Mobs who throw spells you can't evade should generally be taken out first anyway. Keep your distance and take advantage of being a ranged class as well as your CC spells.
