Item	Description

Version history

Version	Changes
0.3.0	No longer has special behaviour causing it to detonate as soon as it stops bouncing. Instead it strictly obeys its detonation time like other Grenades. Gas cloud damage per second is now affected by critical hits.[Undocumented]
0.2.0	Many Skills have had their base damage and/or damage growth per level rebalanced. Most of these changes are not specifically mentioned below as the changes are too widespread. The mana cost for all Attacks, Marks and Warcries has been reduced, most notably at higher Gem levels. Gas Arrow, Gas Grenades and Decompose now have a limit of 6 Poison Clouds. Skills with Expanding ground effects were unintentionally scaling radius over time instead of area of effect. They still scale the radius, though we have updated the descriptions and lowered the values on many of the affected skills: The Poison Cloud on Gas Arrow, Gas Grenade and Decompose now gain 20% more Radius per second, up to a maximum of 80% (all previously 50%, up to a maximum of 200%).
0.1.0b	Gas Grenade's explosion base damage has been reduced to 150%-468% at gem level 1-20 (previously 240%-749%).
0.1.0	Introduced to the game.
