This is my customed Dying Light Mod that combined a couple of mods. I spend a whole day modifying codes, assorting files, and testing and mending this set of mods. Probably I am not uploading any updates because I experienced multiple crash after several updates.

The mods used are:

Harran Unleashed PLUS Advanced Moves (for advanced moves)
Harran Unleashed PLUS Advanced Moves Overhaul (On Indefinite Hiatus) at Dying Light Nexus - Mods and community (nexusmods.com)
I managed to extract and modify the files for Advanced Moves. I STRONGLY RECOMMEND that you don't upgrade FAST RUNNER skill and the subskill, or you'll feel like a dope volatile.

Harran Unleashed: Panic Mode
Harran Unleashed at Dying Light Nexus - Mods and community (nexusmods.com)

I Am Legion - Return to Harran - Insanity Mode
I Am Legion - Return to Harran at Dying Light Nexus - Mods and community (nexusmods.com)
I Failed to make Rais Men armed with rifle.

Bozak Dockets Every Trial Completed
Bozak dockets every trial completed at Dying Light Nexus - Mods and community (nexusmods.com)

Legend Skills Overhaul
Legend Skills Overhaul at Dying Light Nexus - Mods and community (nexusmods.com)
Removed movement speed modification and Grappling Hook enhancement because I felt dizzy and became a Spiderman.

True Grenade Launcher
True Grenade Launcher at Dying Light Nexus - Mods and community (nexusmods.com)

How to apply
ctrl c v data3.pak to DW folder, just like what you do with other mods.

Summary
All biters become runners and more aggressive.
Grappling Hook nerfed.
Legend Skills overhauled(refer to the link) - Removed movement speed modification and Grappling Hook enhancement because I felt dizzy.
Advanced moves added(refer to the link).
Bozak Dockets are earned every round, >=5 per round; i forgot how I set
Ice launcher(DLC)is now Grenade Launcher.
I tried to add Bear Arms Mod - 22 New Weapons at Dying Light Nexus - Mods and community (nexusmods.com), but the codes are too complicated to spend that significant amount of time, endurance and glucose for my brain activity.
For detail just refer to the mods above.


 ---------------------v0.2----------------------------------
removed bear arms stuff. as far as i can.
probably solved issue of blueprint list, so that it displays your own inventory.

----------------------v0.3---------------------------------
tried to fix blueprint inventory, and failed
----------------------v0.4
fixed blueprint inventory as far as i can. 

CAUTION: GLITCH INCLUDED!!!
Hypermod and Pilgrim Outpost count are disabled while using mod.
beware of the movement speeds.
If you added other modes or modified this mode, BE CAUTIOUS WITH THE GLITCH: especially with your PISTOL, ARROWS AND RIFLE; the power of all of em nerfs, pistol and rifle has infinite ammo, and ALL arrows are gone to Somalia. I'm not sure if guns become volatiles just for DLC guns.
      L I found that DLC guns go volatiles when some mods(Harran Unleashed I guess) on or off. So be careful if you are using DLC weapons and applying mods.
      L This happens when DLC is on or off. The way to solve this is either to craft DLC weapons again, from the spare weapons you have, so that this issue is totally solved and the weapons function properly, or to on and off the DLC, so that it is paritally solved and the weapons are modded into the degree that they are close to its proper functioning.
If you are touching the codes, DO NOT TOUCH the BUFFS.XML; that's the source of game crash glitch. lyr_amm_buffs too.
If you use this mod, there will be progress glitch on museum mission(Jade showdown session).
using 0.4, you will experience glitch in bozak that not all dockets give gold weapons.
