Lexa I think you showed a great way to get ES + Deathwish into a good spot. Because the 1 second limitation isn’t that nice.
Deathwish:
While channeling Arcane Torrent, Disintegrate or Ray of Frost, your overall damage dealt is increased by 85-125%. Your channeling skills benefit from this 3 times.
Etched Sigil:
While channeling Arcane Torrent, Disintegrate, or Ray of Frost the damage of your Arcane Power Spenders is increased by 50-100%, this counts 3 times for your channeling spells and you also cast one of your other damaging Arcane Power Spenders every second.
That shifts the power from your other spenders back to the channeling. It would in fact weaken alot of existing builds, Hydra, Meteor, Twister. But I think it would be worth it. Cause balancing would now be easier.
Agree with your Hergbrash’s Bindings suggestion, but not sure about no ramp up time anymore.
But now I will go wild if suggestions to my most beloved skills. The goal should be in the future to make more runes desirable with legendaries, that not only increase the damage but also change the playstyle.
Arcane Orb
Bracers: "The explosion radius of Arcane Orb is increased by 25-35%, and you take 35% less damage after casting a Signature spell for 8 seconds.
The damage of all the other Arcane Orb runes needs to be doubled. And here are Weapon Items for each rune.
Weapon: Sparks damage is increased by 30-45% for every enemy hit with your last Spark. While hitting less than 5 enemies Sparks damage is increased by 300%.
Weapon: Scorchs burn effect is increased by 400% and the explosion spreads five splashes, that are five meter setting the ground to burn randomly.
Weapon: Arcane Orbit now produces every second two Arcane Orbs swirling around you and deals 300-350% more damage.
Next is Arcane Torrent
Wand: While casting/selecting Death Blossom grants you also the effect of Arcane Mines and Cascade. The damage of Arcane Torrent is increased by 600-800% but you also take 30% more damage. *Imagine a Wizard going insane, teleporting in a big group of demons causing havoc, but also hurting himself.
Thread needs still attention.
