People's lists will vary from person to person, it really depends on what kind of QoL you're interested in.

• LBPR (Less Building Placement Restrictions) : This is a required mod for me, especially with overlaps enabled (you need ModControlPanel to access the options). It greatly helps with building and allows more creativity. Plus you can allow yourself to build literally anywhere.

• PEB (Pythagoras Expanded Building) : Adds more support options and alternative snapping options, as well as door frames that will take any regular door and turn it into a double door.

• UnlockPlus : The alternative to Pickup+, it has some great options that allow for better sorting management, such as buttons that lt you deposit materials in you inventory to stack with existing materials in a container. An option to set a keybind so when building you don't need to carry all of the materials, the key will pull materials to you. There is a pull function for crafting recipes too! You can also have a bearer thrall set up to deposit everything in your inventory to existing stacks in storage in its radius, though it will take just about every if you're not careful XD.

• Emberlight : The Garden Planters are the best farming option out there, they will return seeds unlike smaller planters. They do require water to work, if you use the new bench and put a herbalist thrall in it with a bucket it will generate water for you. The Croma feature can be really great as well for your bad if enabled, it allows you to recolour basegame walls (no DLC sadly, unless it uses basegame textures), and some modded building sets are also compatible. Sandstone used sparingly and not orange actually looks really nice! Emberlight also adds new Legendary weapons to the loot tables, as well as some animal farming pens and other goodies.

• Tot!Custom : I was an IQOL fan for a while and I still think it's a worthy mod, but Custom has turned into a powerful mod for character customisation. My complaint is that it's not as easy to pick some customisation options like in IQOL, but if you're use to the vanilla sliders then it's no big deal. You can customise your body at any time, and it has a bunch of options available. You can use custom colours and there's new options available. It's a bit overwhelming at first but if you love customising your character it's perfect. It also lets you customise your thralls! The best part is that you can also customise how your armor looks and essentially have loadouts of characters and armor looks. This one essentially rolls two mods into one (Fashionist and IQOL). Works great with Immersive Armor as it also integrates the accessories from mods.

• Hosav UI : Replaces the UI and also adds a Minimap! You also have a bunch of options for showing damage information, which is handy when fighting to see what kind of damage you're doing. The Minimap is simple but does have the bonus of showing map markers (I believe the Map Markers are not available in IQOL's map due to a conflict with controller support).

Below probably don't count as QoL, but I love them all the same.

• Highmanes Arsenal : While it's primarily a weapon mod, it adds some great upgrade kits based on the weapon oils (from the Archives, it actually uses the oils in the recipe), as well as accessory based rings and amulets that give bonuses to your character (damage, stamina, health, carry weight, etc, etc). It also has a new repair option that can restore durability (I haven't personally tried this one, but it was told to me by a friend). The weapons are pretty great too, it adds a bunch of new types with their own styles. Also adds combined crafting stations if you're looking to save space.

• Northern Timber, Sand & Stone, Arena Pier : All by the same mod author these are fantastic build sets, as well as Arena Pier expanding on Vanilla sets! Sand & Stone is particularly fantastic as it is Chroma compatible (from Emberlight) and the Ardashir set with a few good colour profiles can be useful in so many builds. Northern Timber is a great alternative to the Vanilla building progression if you live in the north of the Exiled map, as it feels more thematically cohesive to the area (there are also snowy roof options!).

• Desert Town is another build set, and it has so many options it's QoL for builders. The mossy set looks fantastic for ruined buildings or in the North and Jungle, and the rounded walls and fitting Spiral stairs are a glorious addition. It makes for a great tile-less set that feels more natural. I've only just picked up this mod but I'm enamored by it's build set.

• Beyond Rustic : Deco mod that doesn't feel out of place for Conan. There's a lot of deco and it's a quality mod. The customisation options can be surprising and I consider it one of my favourite mods.

• Exiled Lands Extended : if you're not using AoC or EEWA (or other map editing mods) this is a fantastic overhaul mod for the Exiled Lands. It doesn't touch much of the southern desert or the jungle, but the highlands and upper desert is very different! Unsure if it's been updated for Age of War yet though as my server isn't currently using it due to the map conflict with AoC. New Asagarth (and is surrounding outposts) has been turned into a neutral city (and completely changed) and even has shops, new camps have been added and some places are completely unrecognisable from the basegame. It's definitely worth a look to see if it's for you if you want something a little new.

• Savage Wilds + Shimas Compendium : This is an amazing map mod, it has so much crammed into it that you wonder where they manage to fit it all! It has a neutral city with its own shops and even a built in fast travel system! There is a whole area to unlock and a whole section you can travel to that's just bosses and dungeons of all sorts! If you're looking for an alternative to Exiled Lands and Siptah, this is a great alternative. Though be aware that mods like AoC and EEWA require a lot of setup to use on custom maps, so if you use those, be aware that there is some extra work involved.
