Royal Slimes will automatically despawn 60 seconds after being summoned.
Instead of the default slime sounds, Royal Slimes use the same hit and death sounds as they do in Terraria.
Tips[]
Royal Slimes share similar AI and hop distance with Orange Slimes, meaning they can also be dealt with simply by sidestepping them when they jump at you.
However, as they deal 10 times more damage, more caution should be taken as to not get hit.
Using axes and range weapons are particularly effective against large crowds of Royal Slimes, especially their alternate attacks. This allows you to deal damage to a swarm of them while keeping a distance.
Try to keep the amount of Royal Slimes that are present during a battle with King Slime to a minimum - they can easily overpower and kill you while you're focused on King Slime.
