Poison dynamite

Dynamite(p) is an item made by using a cave nightshade or nightshade on a pot of dynamite, which requires level 50 Firemaking to do. It is primarily used to kill NPCs without gaining combat experience.

When lit with a tinderbox, whether the dynamite is on the floor or in the player's inventory, it will detonate and hit an attackable NPC in a 3x3 area after 5 ticks (3 seconds) for 1-4 damage, with a 25% chance of inflicting poison starting at 6 damage if the target took damage (providing they aren't immune). The poison will deal a total of 105 damage. Only one poison dynamite can be lit at a time, and it will only hit one target, even in a multicombat area. Players can also directly use the poison dynamite on a target, which will then explode after a short delay. This method allows for multiple poison dynamite hits to be stacked on a target before the initial poison dynamite hits. When one of the poison dynamites hits the queued dynamites will not hit. Both methods require the target to be at full health.

The damage type via poison dynamite is the same as the player's equipped weapon, and monster immunities will apply; for example, players must equip a leaf-bladed weapon to damage turoth and kurask via poison dynamite. This also applies for the dynamite's accuracy roll, which is based on the effective accuracy of the weapon that is equipped, and is hence influenced by the corresponding attack bonuses and skill level.^[1] The maximum hit of the initial detonation scales with the player's Firemaking level.^[2]

Poison dynamite cannot be used inside the TzHaar Fight Caves through 2 of the 3 methods of lighting it. Attempting to do so through using it on an NPC or lighting it from the inventory will result in the game chat message It's probably dangerous to set dynamite in so much heat and fire. However, if the dynamite is dropped on the floor and then lit with a tinderbox, it can still be used. It is also not possible to envenom monsters through the passive effect of a charged serpentine helm when using poison dynamite. Players can attempt to light poison dynamite on free to play worlds, however it will never light. Additionally, players may not use poison dynamite in the Basement of Doom, or any 1x1 area such as the cabin of The Adventurous.

Lastly, if the target dies due to poison damage alone, the player may not always receive kill credit and might not receive item drops from the target. This is possible if the target regenerates their HP back to full before the first instance of poison damage is applied.
