Vulnerability bomb detail.png

A vulnerability bomb is a bomb potion that can be thrown. It creates a 3x3 area which lasts 1.8 seconds and applies the Vulnerability effect to monsters standing in it. The bomb has no effect on other players. It can be made at level 103 Herblore in a bomb vial using primal extract, soul runes, chaos runes, bottled dinosaur roars, and a clean dwarf weed. Using a bomb consumes it.

At level 105 Herblore the recipe is improved, which reduces the time taken to make the bomb. At level 107 it is further improved, reducing the number of dinosaur roars required from 2 to 1 and the runes from 5 to 3 of each.

To deploy a vulnerability bomb, use the bomb and then click a tile on the ground around the mob you are trying to debuff. The vulnerability effect can fail to apply ('splash'), but as the affected area's effects linger it will attempt to apply it 3 times (once every 0.6 seconds for total of 1.8 seconds). The probability of the effect applying is based on the players current accuracy against the target. The effect is otherwise the same as the spell - increases damage taken by 10% for 60 seconds. The vulnerability bomb will reapply the vulnerability debuff on a target if thrown again before the duration expires.

Applying vulnerability via these bombs causes aggression from affected monsters. Cast range of all bombs is 9 tiles.

Note: To speed up creation, soul runes & chaos runes may be placed in a Large rune pouch. This can then be equipped to save 2 inventory spaces.
