Acquire the clothing | Mission 3 - Diplomacy Styx: Shards of Darkness Guide

From the baths

The armour you can get from the two places, it does not matter too much, apart from the perspective of time. Personally, I recommend the baths. The only difference is in the later cutscene: Helledryn is wearing either a hooded suit or metal armour.

You can go to the baths from the side, by climbing the rocks

Ideally you should go back onto the wall surrounding the plaza in the centre, from where you can easily jump to the vicinity of the bath. The entrance is being guarded by one goon (or two, but the second will soon leave). But you do not need to worry about him... Note - if you take care of the baths, the objectives at the embassy will disappear.

Again, jump onto the stone steps below, and at their peak, on the edge of the rocks which create the baths, you will a see place where you can grab onto the rock and climb. Pay attention only to the guard from the floor below, make sure that he does not spot you. Additionally, while being inside you will already be in the attic.

The armour lies on a bench in the hallway

Turn left and look down at the hall of a small dressing room - on the bench you will notice a set of armour. Snatch it quickly and go back to the top by jumping from the top of a cabinet. You should use invisibility, though there is one moment, in which everything should go without drawing attention or using any abilities. Be mindful of the elf standing at the corner - she is looking into the corner, but if she spots you, you will have to quickly get back up and wait out the alarm.

What is also important - taking the armour which is lying on the pile also counts as the clothing of an elf, and so the two main objectives are therefore completed. Now go back to Helledryn.

From the embassy

You can get to the quarters through a window, where you will find the disguise

You also have the ability to collect the clothing from the embassy. It is best to jump in there from the vicinity of the altar in the middle and then go straight to the balcony on the first floor. There, through a small window above the door, you will get inside. The clothes lie on a bed guarded by two elves, you can try take them unnoticed, or use invisibility. Immediately after you take the uniform you can jump back to the attic.
