I'm all for heading through that door...but even though Malakai has a decent amount of hit points... his defenses pretty well suck... so I think someone with higher defenses should go first.
Dina tries to think if there is anything she can do about the magic on the door. If not she simply passes through, warning her allies that they might be observed.
OOC:
Not sure if there is something further I can do to neutralize the detection magic.
