Direct change

Cluster Grenade's quality granting Gain 20% of damage as Fire damage (previously 40% reduced Detonation Time).

0.3.0
Direct change

Cluster Grenade: Primary Grenade Attack Damage is now 299-490% at Gem levels 13-20 (previously 199-327%). Mini Grenade Attack Damage is now 174-286% (from 137-225%). Now Fires exactly 18 Mini Grenades in a nova (previously 14), and Mini grenades are fired over a ~17% increased radius.

0.3.0
Direct change

Rapid Shot: No longer has a delay before firing bolts, or 50% less reload speed. It now has 100 Maximum Ammunition at all Gem levels (previously 50-87) and 30-45 Maximum Heat at Gem levels 5-20 (previously 17-24). It now deals 37-94% of Attack Damage at Gem levels 5-20 (previously 21-47%). Quality now grants +0-15 Maximum Heat (previously +0-5). Heat no longer grants Rapid Shot Damage gained as Fire. Instead, reaching Maximum Heat prevents you from using the skill for 10 seconds. It now generates Heat once per attack instead of once per 0.25 seconds. Heat now begins decaying after 4 seconds without gaining Heat, at a rate of 10 Heat per second. Heat no longer grants grenade skills damage gained as fire. Instead, Explosive Grenade and Cluster Grenade consume 15 Heat to gain 50% of damage as fire damage, while Incendiary Shot consumes 30 Heat to gain 50% more ignite magnitude.

0.3.0
Direct change

Fixed a bug where Cluster Grenade's mini grenades could not generate Energy for Meta Gems.
