Thunderbolt

The Thunderbolt mod gives arrows from the Paris or Dread a 7.5% chance per rank (for a maximum of 30% at rank 3) of exploding on impact, dealing 250 base damage to the target as well as to nearby enemies within 10 meters of the blast. Commonly obtained as a bonus mod for Platinum packs, but also dropped on Infested defense maps, as a wave reward or from mobs.

Tips

 * Pair with a high-rank Multishot mod for maximum effect.
 * With a maxed Split Chamber mod (multishot), you'll have a 48.9% chance of having at least 1 explosion (with a 8.1% chance of having two), and thus a 51.1% chance of no explosion at all.
 * When facing groups of enemies at medium to long range, maximize splash damage by aiming for a nearby wall or floor surface rather than directly at an enemy.
 * Since explosive damage is unaffected by the amount of time you've charged the shot, rapid snap shots can be very effective at quickly taking out large groups of enemies.
 * Rapid snap shots at close range can also be very effective at quickly killing yourself. Be careful!
 * Trinity's Link ability is a great tool with Thunderbolt for damaging large, single enemies. Apply Link to a tough enemy and shoot at close range, Link doubles the damage dealt from explosion.
 * Currently, the mod has no effect on bows' stealth properties, killing an unaware enemy with an explosive arrow will not trigger an alarm. However, missing a shot will still be noticed by enemies, be it explosive or not.
