Skill Data - Synthlight/MHW-Editor GitHub Wiki

skill_data.skl_dat holds parameter info for each skill and level. skill_point_data.skl_pt_dat denotes which skills are set bonuses, and their icon colors.

Parameter info is usually a percent modifier to something.

  • Tool Specialist Param 5 is a percent modifier on time. 100 results in no change. 1 reduces the cooldown to 1% original speed (99% faster).

And sometimes it's just a level number directly.

  • Artillery Param 5 simply goes 1/2/3/4/5, for the game to determine which level to use. You can change Artillery 1 to level 5, but you can't really alter the effect each level has through this file. The values for said skill are most likely stored in the pl_skill_param.plsp file.

The Unlock Skills denote which skill is needed to unlock that level. ("Secret" skill levels in-game.) You can remove the unlock requirement thus granting you complete access to all the skill levels without needing the "Secret" skill.

If it's not in either skill file, it's HARD-CODED. Meaning GLHF, you're on your own for trying to find it. There's a remote possibility it's somewhere in the player param file (pl_param.plp), but the editor skips a lot of it so you'll have to hunt it down yourself assuming it's even in there to start with.

Using Set Bonuses as Normal Skills

If you just try to use the skill as is the game gas a good chance of of just crashing. The game does not like it when you use a set skill as regular, or vice versa! You must FIRST change the skill point data file to change whether the skill is a set bonus or not. You may also need to remove/replace the skill referenced in armors/gems to make sure it's used as a set or regular skill. Skipping that may result in crashes.

To use a set skill as a regular skill:

  • Uncheck the Is Set Bonus box on skill_point_data.skl_pt_dat for the skill in question.
  • Edit armor.am_dat and remove/change armor pieces using the target skill as a set bonus. (If you don't, viewing one of those pieces may result in a crash.)
  • Now you can use the set skill as a regular skill.

It does cause some minor odd bugs in the game however:

  • It shows that you've unlocked the skill, but you still require the pieces needed to activate it. (ie, if you uncheck Teostra's Technique as a set-bonus, the game will show it "unlocked" with 1 Teostra armor part, but you'll still need 3 to get Master's Touch.)
  • Skills like True Spare Shot will show up as "Nargacuga Essence has activated" instead if you uncheck that as set-bonus.
