Version history

Version	Changes
3.23.0	Quality now provides 0-40% chance to Shock enemies (previously 0-20%).
3.16.0	Tempest Shield has been reworked to become a 25% Reservation Effect that provides a large amount of Spell Block as well as an Immunity to Shock. It no longer has +3% Chance to Block Attack Damage while holding a Shield. It now has +18% Chance to Block Spell Damage while holding a Shield at gem level 1, up to +25% at gem level 20 (previously +3% at all gem levels). It still has the property of shooting out Lightning on Block, and the Damage has been significantly buffed: Now has Deals 38 to 115 Lightning Damage at gem level 1 (previously 24 to 26), up to 896 to 2688 at gem level 20 (previously 284 to 426).
3.6.0	Mana Cost at gem level 1 is now 7 (was 17). Mana Cost at gem level 20 is now 16 (was 21).
3.5.0	Now also grants +3% chance to block Spell Damage.
3.3.0	Cast time lowered to 0.25 seconds (from 0.5).
