Explosive Bolts


From Diablo Wiki

Jump to: navigation, search

Explosive Bolts is a skillrune effect of the Wizard's Shock Pulse skill.

The basic bolt damage or behavior does not improve with this rune, but with the rune active, monsters killed by the bolts explode in a dome-shaped electrical effect that deals 70% weapon damage to every enemy within 10 yards. (Additional monsters killed by the dome bonus do not also explode into a dome effect.)

While this effect does nothing to boost overall damage against single targets, it greatly improves the effectiveness against large groups, as the domes add considerable AoE damage. This rune is hugely useful when it first becomes available, as low level enemies can be killed by one or two Bolts, and will then explode, causing a chain reaction of death throughout the group. Low hit point monsters that attack in bunches are especially vulnerable to this rune.

The rune becomes useless at higher levels, when enemies have greatly increased hit points, do not die quickly, and hardly flinch at a 70% bonus damage splash.
