So, the wiki shows this: Here is an example of a the Cooling EPP Upgrade with stats on it. Type: Cooling EPP Upgrads Stats: +20% Damage, +5% Defense, +20 Energy, +20 Health Example: /spawnitem heatprotectionback 1 '{"statusEffects":[{"stat":"powerMultiplier","baseMultiplier":1.2},{"stat":"protection","amount":5},{"stat":"maxEnergy","amount":20},{"stat":"maxHealth","amount":20},{"stat" : "biomecoldImmunity","amount" : 1.0 },{ "stat" : "biomeradiationImmunity","amount" : 1.0 }, { "stat" : "breathProtection", "amount" : 1.0 }]}' I tried using that to spawn the custom item. However it didn't actually give me heat protection (as the base item should). Is that because it's using custom specified abilities and needs "biomeheatImmunity" added in somewhere (or hotImmunity?). Can someone give me a hand, and maybe make sure the wiki is correct?
