Trying to make a specific character NOT cause moisture in the world when using a Telelocator

[4here4]

Hello, I have a custom character I'm making for myself and a few friends to mess around with. The only problem I'm running into is I want him to be able to teleport himself/others with a telelocator staff without causing it to rain. I'm afraid I don't know if this is something that would even be possible to code, so please don't feel obligated to find a solution. Any help would be greatly appreciated. Thanks in advance!

AddPrefabPostInit(
    "purplestaff",
    function(inst)
        if not GLOBAL.TheWorld.ismastersim
        then
            return
        end
        local spellcaster = inst.components.spellcaster
        if spellcaster
        then
            local spell_old = spellcaster.spell
            if spell_old
            then
                spellcaster.spell = function(staff, target, pos, ...)
                    local TELESTAFF_MOISTURE_old = GLOBAL.TUNING.TELESTAFF_MOISTURE
                    local caster = staff.components.inventoryitem and staff.components.inventoryitem.owner
                    if caster and caster.prefab == "yourprefabnamehere"
                    then
                        GLOBAL.TUNING.TELESTAFF_MOISTURE = 0
                    end
                    local rets = {spell_old(staff, target, pos, ...)}
                    GLOBAL.TUNING.TELESTAFF_MOISTURE = TELESTAFF_MOISTURE_old
                    return GLOBAL.unpack(rets)
                end
            end
        end
    end
)

Untested but should be snaps.  Replace yourprefabnamehere with your character's prefab name.

Hmm... doesn't seem to be working. I might have placed it in the wrong spot, or perhaps some other bit of code is conflicting? Attached is my modmain.lua

Any ideas?
