The Lightning Aura Rod, Cane, and Staff are special sentry summon weapons that summon a small base at the point clicked and a Lightning Aura sentry minion (an orb) which hovers over the base. Each Lightning Aura sentry is a circle of lightning aura centered on the base that damages enemies repeatedly as they go through it. It has a range of 19 tiles (1 tile is the center, and 9 on each sides and upwards). The Rod is sold by the Tavernkeep for
50000*5 , the Cane for 250000*25 , and Staff for 1000000*100 .
Lightning Aura weapons completely ignore enemy defenses by adding half the enemy's defense to the weapon's damage. The Lightning Aura Staff, for example, always inflicts around 34 damage on any enemy, regardless of its defense stat. The Lightning Aura weapons state tripled damage numbers in their tooltips as an estimate to reflect this unique ability.
Lightning Aura sentries are boosted by the Monk armor and Shinobi Infiltrator armor set bonuses, which increase their attack rate (from 2 attacks per second to 2.4 attacks per second) and allow them to deal critical hits. The critical strike chance of these weapons will always be locked at 25% (Shinobi Infiltrator), or 16.7% (Monk), and will not be boosted by the weapon's modifier or any other boost to critical strike chance. The Shinobi Infiltrator armor also increases the size of the Lightning Aura summon.
- Completing the Old One's Army event on any difficulty sets a hidden attribute for both the world it was completed on and the character who completed it. Any characters, including newly made ones, who visit that world may then use Rods, Canes, and Staves on that world. The character who completed the event may also use Rods, Canes, and Staves on any world.
- 閃電光環的最大半徑是 9 格，頂部的'球體'位於從基座向上數的第十格。如果在矮於 10 格（被物塊或平台所阻擋）的空間中召喚，閃電光環會被擠壓縮小，最小能被壓縮到半徑為三格，球體位於基座上方第四格。
- 閃電光環需要從頂部球體到位於其半徑範圍內的敵怪有直視視線才能對其造成傷害。在矮於 10 格的空間裏召喚閃電光環將讓球體位於物塊之中，使其大部分攻擊範圍都變得無實際意義；不過它仍能對正下方的敵怪造成傷害。雖然平台會縮減閃電光環的範圍，但它們並不會阻攔視線，使得閃電光環能夠正常運作。
- 地牢守衛，以及任何其他碰巧擁有超過 999 防禦力的敵怪，都被排除在閃電光環的防禦補償能力之外，並且會使閃電光環的傷害正常減少。
- 閃電光環有時會摧毀法師 AI敵怪所射出的射彈。
- 閃電光環可以有效地對抗蠕蟲 Boss。
- A Lightning Aura sentry emits light, therefore it can be useful when exploring caves to locate undiscovered sections. Attempting to place it in a solid area will not use mana, so it can be freely used to probe "blank" areas for possible caverns. Binoculars or similar can be helpful to extend the area mapped by the light.
- This sentry can be displaced. This behavior can lead to some interesting movement of the sentry when placed in narrow sloped tunnels, like those of the Underground Desert, and it can end up some distance away from it's intended placement, inside walls, or even completely off screen.
- Prior the Lightning Aura Rod's introduction to Terraria, the Slime Staff was the weakest summon item in the game (half base damage, but ignores defense).
