What type of damage do Grasping Darkness deal?

I'm looking on the official Guild Wars Wiki and I found that Smite Crawlers deal slashing damage. I wish the wiki would be consistent, as it does not say what type of damage Grasping Darkness deal.

physical. slashing.

grapsings deal physical damage, any shiled will give you the best ar vs them, as for smite crawlers it doesnt really matter what thier attacks do thier major form of damage comes from thier spellcasting(holy dmg), if your planning to tank them a sheild with a base -X dmg while w/e would be better then bringing only a +10vs slashing
