Explosive Trap sentry summons

The Explosive Trap Rod, Cane, and Staff are special sentry summon weapons that summon an Explosive Trap sentry minion at the point clicked. Each Explosive Trap sentry is a small device on the ground that explodes when an enemy comes in close proximity. It does not disappear upon exploding, but remains at its summon point to explode repeatedly until its time is exhausted or the Old One's Army event ends. The Rod is sold by the Tavernkeep for 5 Defender Medals, the Cane for 25, and the Staff for 100.

The Rod is always available. The Cane becomes available after defeating one Mechanical Boss, and the Staff becomes available after defeating Golem. The three different versions cause an identical effect, but with varying statistics, with the Staff being the most expensive and the most powerful.

These weapons can only be used outside of the Old One's Army event after the event has been successfully completed. Completing the event on any difficulty allows Rods, Canes, and Staves alike to be used outside of the event.

During the Old One's Army event, Etherian Mana can be collected, which allows the placement of multiple Explosive Traps that remain permanently until the event is over. Etherian Mana cannot be used outside the event.

Explosive Trap sentries are boosted by the Huntress armor and Red Riding armor set bonuses, which cause their explosions to 'oil' enemies. Oiled enemies take 2 more damage over time from the On Fire!, Cursed Inferno, Frostburn, or Shadowflame Debuffs. However, this extra damage does not stack.

Tips

 * The Explosive trap detects enemies in an area a few blocks to both sides and several blocks high. The explosion can reach up to the height of the detection area. Thus, the trap can detect and damage flying enemies to a degree.
 * The Explosive trap fires instantly after its attack cooldown ends. This also means it will attack instantly on being summoned. Rapid summoning will dramatically increase its natural firing rate at the cost of high mana consumption. This style of usage can be effective against mobs that are too powerful to die to a single shot, and can be useful in boss fights as long as there are suitable placement options. To maximize this effect, this sentry can be set directly on an enemy that is near the ground.
 * The Explosive trap has a faint glow, and can be used to see into nearby surrounding caves.
 * The Explosive trap fires slowly and has a fairly insignificant range. When combined with Huntress armor or Red Riding armor, it fires much faster and benefits from the summon damage boosts of those sets. A cluster of 3 or 4 traps at each portal in the Old One's Army event can kill everything but Ogres before they leave the damage area.
