Note, I refer to Void's post on Buff and Damage mechanics several times below. Here is the link to that extremely informative post: http://us.battle.net/d3/en/forum/topic/14058607023
If a gem is not listed it is because either the impact is obvious (Simplicity's Strength) or there really isn't much notable in terms of interaction with Wizard abilities. If you find a unique aspect of a gem and a Wizard ability that I don't have please comment below and I'll include it.
Zei's Stone of Vengeance
- Damage you deal is increased by 4 [+.5% per rank] for every 10 yards between you and the enemy hit. Maximum 20.00% increase at 50 yards.
- 20% chance on hit to Stun the enemy for 1 second. (Requires Rank 25)
Notable wizard skill impacts
- Damage is a multiplicative increase after most other effects are calculated. (see void's post) This means it increases damage done by DOTs or other effects as you increase range to the target.
- Hydra - damage increase is based on the Hydra distance from target, not the Wizard distance.
Wreath of Lightning
- 15% chance on hit to gain a Wreath of Lightning buff, dealing 600 [+10% per rank] weapon damage as Lightning every second to nearby enemies for 3 seconds.
- While under the effect of the Wreath of Lightning, gain 25% increased movement speed. (Requires Rank 25)
Notable wizard skill impacts
- Chance is checked based on skill proc coefficient.
- Damage is increased by +lightning damage percentage.
- Speed increase allows you to exceed the +25% speed increase cap from gear/paragon
- Storm Armor - will trigger Wreath of Lightning
- Blizzard, Black Hole - chance only checked on initial cast, not on the DOT damage ticks
- Hydra will not trigger this effect (true??)
- Mirror Image - your mirror images will not trigger Wreath of Lightning (true??)
- Archon - can you get the buff in Archon form??
- Tal Rasha's set - can trigger a lightning meteor from a strike
- Provides a dose of lightning damage for the purposes of Elemental Exposure
Gem of Efficacious Toxin
- Poison all enemies for 2000% [+50% per rank] weapon damage over 10 seconds
- All enemies you poison take 10% increased damage from all sources. (Requires Rank 25)
Notable wizard skill impacts
- Poison damage DOT does not critically hit
- The 10% increased damage applies to other party members as well.
- The 10% increased damage is additive to other damage.
- The poison damage is applied before the actual skill damage, making it very effective against Corrupted Angels who select a poison damage shield letting your main skill damage through.
- Blizzard - applied whenever damage is done (yes, this is incredibly effective.)
- The Firebird set tier 6 DOT does not trigger the poison effect.
- Triggered by Wreath of Lightning strike
- Damage continues ticking even after death
Pain Enhancer
- Critical hits cause the enemy to bleed for 1200.0% [+30% per rank] weapon damage as Physical over 3 seconds.
- Gain Blood Frenzy, granting you 3% increased Attack Speed for each bleeding enemy within 20 yards. (Requires Rank 25)
Notable wizard skill impacts
- The bleed effect itself does not critically hit.
- Damage is increased by +physical damage percentage.
- Triggered by Wreath of Lightning strike
- Hydra - will cause the bleed on critical hits (tested??)
- The bleed physical damage is applied before the actual skill damage on a critical hit, making it very effective against Corrupted Angels who select a physical damage shield letting your main skill damage through.
- There is no buff icon to indicate you are getting an Attack Speed increase, however it does show up on your character sheet.
Mirinae, Teardrop of the Starweaver
- 15% chance on hit to smite a nearby enemy for 2000% [+40% per rank] weapon damage as Holy.
- Smite a nearby enemy every 5 seconds. (Requires Rank 25)
Notable wizard skill impacts
- Chance is checked based on skill proc coefficient.
- Damage is increased by +holy damage percentage.
- Hydra - will not trigger the effect (true??)
