So I've ran into a problem. Adding potion effects won't work. I have this in my player respawn listener. //Strength Potion Effect (20 ticks = 10 seconds) p.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 18000, 1)); I want players to spawn with Strength I effect for 15 minutes, but it won't work. WHY WON'T THIS WORK?
