Here is a curio check

const checkCurios = (event, curiosList) => {
    let curios = event.player.nbt.ForgeCaps['curios:inventory']
    let key = false;
    curiosList.forEach(curio => {
        if (curios.toString().contains(curio)) {
            key = true;
        }
    })
    return key
}```
and you use that like so:
```js
const talismanBuff = (talisman, effectList) => {
    PlayerEvents.tick(event => {
        const { player } = event;
        if (player.age % 200 === 0) {

            let hasCurio = checkCurios(event, [talisman]);
            if (!hasCurio) return

            effectList.forEach(effect => {
                player.potionEffects.add(effect.id, 1200, effect.amplifier, false, false);
            });
            
        }
        
    });
};```
if you now just do this:
```js
talismanBuff('mod:talisman', [{id: 'minecraft:speed', amplifier: 2}])```
you will now get speed 3 when wearing `mod:talisman`

the check runs every 200 ticks (10 seconds) and gives the effect for 1200 ticks (60 seconds)
