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.
- 闪电光环的最大半径是 9 格，顶部的'球体'位于从基座向上数的第十格。如果在矮于 10 格（被物块或平台所阻挡）的空间中召唤，闪电光环会被挤压缩小，最小能被压缩到半径为三格，球体位于基座上方第四格。
- 闪电光环需要从顶部球体到位于其半径范围内的敌怪有直视视线才能对其造成伤害。在矮于 10 格的空间里召唤闪电光环将让球体位于物块之中，使其大部分攻击范围都变得无实际意义；不过它仍能对正下方的敌怪造成伤害。虽然平台会缩减闪电光环的范围，但它们并不会阻拦视线，使得闪电光环能够正常运作。
- 地牢守卫，以及任何其他碰巧拥有超过 999 防御力的敌怪，都被排除在闪电光环的防御补偿能力之外，并且会使闪电光环的伤害正常减少。
- 闪电光环有时会摧毁法师 AI敌怪所射出的射弹。
- 闪电光环可以有效地对抗蠕虫 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).
