Avoid Bonus by Class
This hack changes the avoid calculation for an arbitrary list of classes. I personally use it with DSFE avoid by @GratedShtick but it functions just fine in vanilla(Even if its a bit redundant there) as the actual calculation add an extra bonus luck and speed. You can define what classes you want to have boosted avoid and then point to it in the PreBattle Calc Loop. By itself it just inflates avoid even more so you’ll most likely want to use this in conjunction with a change in the avoid formula.
Fire Emblem Heroes Staff Damage Calc
This hack changes the damage calculations of staff weapons to output half damage mimicking the behavior in Fire Emblem Heroes. On the surface its pretty simple but I made it with options in mind. Fire emblem heroes gets up to a lot of shenanigans internally so there are 2 configurable options to follow that behavior. First the WrathfulStaffList, a list of staves that innately ignore damage calculation change and the TruePowerIDLink, which is a skill ID to allow certain units to also bypass the change. It should go without saying but you need to make staves able to attack for this to have any use. You probably wanna pick up murder sticks by @Zeta if you’re gonna make staff weapons though.
Bonus Avoid and Crit Avoid/Dodge/Crit Evade by Item
This hack lets you define weapons that grant bonuses or penalties to a units avoid and/or crit avoid(Dodge)[Crit Evade] similar to Fire Emblem Fates. Configuring is pretty easy since its just 2 list and a macro invloved. Using the macro you can define what weapon, whether or not its a bonus or a penalty and, the actuall value you want. Just a heads up you can make an item in both lists but you cannot have an item that gives a penalty and a bonus to the same stat. Between this and support bonuses you can make Crit avoid a real stat and give your player actual counter-play to Berserkers with Killing machine.
Item Type Weapon Triangle Advantage
This hack based on @Sme’s ItemSpecificWTA and lets you define arbitrary weapon triangle interactions but instead of Item vs Item it’s Item vs Type. So you can have a bow with WTA against all Swords.
Its super simple you pick an item and a type. For the bonuses themselves however, you get to set those independent of your actual weapon triangle. If that’s not your thing you can just change this alongside the real weapon triangle.
