PSA: You can't hide helmet in Dragon's Dogma 2, but you can raise the visor
So picture this situation. There you are, with your fancy RPG fantasy gear on your detailed custom character in Dragon’s Dogma 2. You’ve built the perfect armor set for your vocation, and set out to the world ready to take on the horrors of the wild in style. You've got a great set of armor to fit the situation - but the helmet is covering your beautiful character's face, which you spent hours creating. The first instinct for a lot of players is to dig through the menus for a Hide Helmet button. Which, in this game... is a problem. Allow us to explain.
You can't Hide Helmet in Dragon's Dogma 2. Here's why
In many RPGs in the vein of Dragon's Dogma 2, you're typically able to at least hide the helmet you've equipped from physically appearing on your character model, while retaining the RPG stat boosts that wearing the gear gives you. Not so in Dragon's Dogma 2.
DD2 is a game that's fairly dedicated to RPG tradition as established in tabletop games, and it aims for realism and truth to the game world's design. There's no invisibility spell you can cast to render clothing items imvisible - and as such, you can't hide your helmet.
Basically, because Dragon's Dogma 2 aims for realism with the way all of its mechanics are implemented, this isn’t as easy as you might think. If you want the stats for an armor piece, you will need to actually wear it.
With all of this in mind, there's not too much you can do other than keep helmets in mind when coming up with an armor set. If you spent all that time in the character creator crafting a gorgeous Arisen and feel the need to flaunt it, you may just have to forgoe the stat boost that helmets provide and not wear one. It's totally possible to play the game this way - it won't hobble you that badly. Thankfully, there are no armor set bonuses in DD2.
If that turns your stomach, there is a middle-ground solution. Read on...
How to raise your visor in DD2
Before you equip a helmet in Dragon's Dogma 2, your only options will be Equip, Give, and Cancel. However, if your helmet of choice has a visor, another option will appear, context-sensitive, once the helmet is equipped.
Once a helmet with a detachable or moveable visor is equipped, you can actually raise that helmet's visor by clicking on the helmet in the equipment or inventory menu while it's equipped and choosing a new action named “Raise Visor” below a now grayed out Give action.
If you’d like to reset it to its original state, you will just need to click “Lower Visor” to cover your face once again.
Doing this is entirely for aesthetic reasons. You do not gain or lose any stats, but if you want to be fashionable this is a perfect little solition.
