Best tank to pair with monk?

[Shurrikhan]

The war debuff does both physical and magical damage so it's better than either, plus the magic damage reduction stacks with the int down. That being said, you can really stick with whatever tank you like best. The world first clear on the current savage content was done with a drk and mnk in party. The Int down debuff is becoming less and less relevant anyways thanks to darkness type damage.

Darkness type? I would think that a Int debuff would reduce all outgoing spell damage, even if "true damage", as it affects the source stat rather than interacting with the damage type itself. Which is probably why almost every "true damage" (non-mitigatable) attack I can think of has been while the attacker/source isn't targetable (e.g. "Ragnorok" casting the spells in T9, rather than Nael). If that's a non-mitigatable type I could however see Storm's Path becoming useless against it.
