Go here for a latest compilation of all of my spell mod that work for both Sorcerer and Mage Mass Enchant

Change was made to Lassitude:
1. It will now stop the movement of enemies that touch the AoE completely, work on most enemies on testing, some will product weird behavior.
2. Both Lassitude and High Lassitude are the same (due to technical limitation).
3. Increase the spell cast time, reduce the duration of the sphere, it will still inflict Torpor debuff (for balance purpose)

Warning:
Bug :When cast on a group of enemies and quickly run away, on reaching a certain distance the game will crash.
This issue is likely cause by the game despawn enemies at certain distance away from the player. For now try to not run away (too far) while the spell is working .

Update: Unfortunately the bug can't be fixed, so I can only reduce the spell's duration to lessen the chance of crashing, as compensation for this, the spell's radius have been increase and cast time reduced.
1. May cause unintended effect on gameplay under certain situation/ with certain enemies, during testing there are 2 times crashing 1 on an area with ghost, 1 with bat, but I do not know if its cause by this spell or not because my game's file is under heavy modification, so to be safe save frequently until it can be confirmed. Its possible that these crashes happen when the player move too far away from the AoE while its working.
2. While the enemies will appear to be freezing completely, if its in the middle of doing an attack, come close will result in getting hit by said attack. This is how the game's mechanic suppose to be, I don't think it can(should) be change.
3. Casting many in quick succession won't work, the enemies need to break free of the spell for it to be able to apply again. This is how the game's mechanic suppose to be, I don't think it can(should) be change, think of it as a part of balance.    
4. Actual enemies speed is set to 0.5% of original, I avoid 0 because it feel potentially buggy.


A demonstration video (note that this mod doesn't include fast casting mod, and some value like knockdown/stagger/damage may be
different in actual gameplay)


Notes: come with my previous Maelstrom's Dark effect removal mod, Frigor EX mod, Voidspell EX mod, Ingle EX mod. Detail:

Any feedback/question  is welcome, but I may or may not be able to Fix/change the mod (due to technical limitation, logical limitation,....) .    

Instruction:

• Make a backup of your wan.arc file ( in DDDA\nativePC\rom\wp\w1 ) and stk27.arc, stk00.arc (in DDDA\nativePC\rom\sk\s1\ ) as
  obviously it will overwrite if you have any other mod that change these files such as magic mods .
• Download extract and replace wan.arc (in DDDA\nativePC\rom\wp\w1) and stk27.arc, stk00.arc (in DDDA\nativePC\rom\sk\s1\ ).

Some thought from making this spell/DDDA spell modding in general:
1. This is the most complex spell I have made so far, spent a great deal of time working on it, I hope its not causing crashes because it would be hard to fix if it is.
2. I want to make it stop everything include projectile, magic, ... all like a real time stop but after spent a lot of time trying I don't think there is any mechanic in the game that can be modify to do that unfortunately.
3.The early concept making use of Hitstop mechanic but unfortunately Pawn absolutely can't inflict Hitstop on enemies so I have to go many extra miles to find an alternative, this is make using an attribute of Assassin class's Wind harness skill.
4. I was consider making it hit allies as well for the lol or the high risk/high reward feeling, but after consider pawn AI it was scraped.
