The Super Dummy is a craftable Pre-Hardmodesummoning item which spawns a Super Dummyenemy when used with left-click. This enemy is nigh-invincible, with a whopping 9,999,999 health that it is constantly regenerating. It also cannot be killed by damage-over-time from inflicted debuffs. However, right-clicking with the Super Dummy item in hand will cause all Super Dummy enemies to immediately be killed.
Due to the Super Dummy enemy's high resilience and inability to harm the player (despite being an enemy), it is considered an improved alternative to the Target Dummy. It features several practical advantages to Target Dummies, including more accurate DPS numbers when using the DPS Meter or any of its successors, the ability for weapon projectiles to home in on it, and the ability for minions to target it.
It can be useful to activate the special effects of weapons, such as the lifesteal of Vampire Knives, or weapons that grant buffs on hit, such as Grax.
This will not work during boss fights.
By spawning a handful of Super Dummies, enemy spawns will cease, due to Super Dummies counting towards the enemy max spawn. This can be very handy for building in high-spawn locations such as the Jungle.
Be wary of where the dummies are spawned, however, as if the player moves too far away from a cluster of them, they are prone to despawning.
It is possible to kill the Super Dummy if the player is able to deal enough damage to it to surpass its high life regeneration and it is currently not under any damage-over-time debuffs.
