Oracle's Moment of Vulnerability

This ability is pretty thematic and allows for some monstrous burst when the stars align, but getting those stars to align is often clunky and the effort expended is sometimes just pointless.

1) Requirement for hitting primed enemies means you spend more time looking at the boss's debuffs and buildup progress more than watching the action on screen. The icons on the enemy can sometimes get lost in the visual effects so the debuff bar is a more reliable source. Perhaps have the skill button visually light up when there's a nearby primed enemy for more clarity.

2) Losing the window to use the skill when the boss is fully frozen, electrocuted, or heavy stunned makes heavy investment into those statuses feel wasted. Skills like Lunar Assault with a big freeze modifier mean you can go from 60% buildup to full freeze, and then not be able to use this cool ability. Freezing Mark and Voltaic Mark are in a similar place, since although they augment your ability to buildup freeze or electrocution, they automatically apply the immobilization effect when the enemy is primed, making the setup feel wasted. Perhaps using a delayed debuff effect like the new Lightning Warp could help address this.

3) Electrocution is not supported on the Druid's side of the passive tree or in their innate skills. Lightning damage is either from Thunderstorm or empowered Wyvern attacks, making it difficult to specialize that damage type. Electrocution status buildup is mostly enabled by Dexterity skills in bows as well, which is the opposite side from the Str/Int hybrid of Druid. Additionally, this patch added many support effects that triggered from shock, so giving all that up to instead enable electrocution via support gem gives us no new toys to experiment with.

4) There is no control on where the visage shows up. Sometimes it's beside the boss, sometimes it's basically toppling to the edge of the screen from being stunned. When you're in melee, the visage can appear behind the boss, and to hit the visage you need to maneuver around the boss. By the time you can reach the visage target, the duration on it has run half its course giving you a very small window to damage it. I understand that this may be a technical limitation of needing space to spawn and collision getting in the way, but it would be cool to just the visage almost overlap the boss so to capture the "future sight" fantasy of the skill.

I've been playing around with Align Fate and I really like it. If you go full spell casting, it feels pretty rewarding to juggle your skills, prioritizing casting the spell the visage casts. Align Fate with Cast on Crit is pretty autonomous gameplay. The visage for both skills seems pretty erratic as you say. I definitely recommend GGG take a serious look refining this.

I do want to get around testing Moment of Vulnerability but I imagine using something like Thunderstorm for Shock, if you're using plants, with Enervating Nova on staff will let you benefit from both Shock and primed for electrocution? Or, flip it around and use the Electrocute support gem on Thunderstorm (for mobbing) and Lightning Bolt on staff (for Shock on bosses)? Don't forget, the Oracle tree lets you add 3-51 flat lightning damage to attacks and you could always throw on Wake of Destruction boots to generate Shocked Ground, which could then be picked up by Tornado. Another method is to use Shocking Leap on werewolf's Pounce and use Tornado after to prime for electrocution. Don't forget the spells you can put on Spell Totem. Druid skills are str/int based so I don't see a huge issue with grabbing a crossbow for electrocution buildup either (which scales with str/dex and can have reduced attribute requirements), especially when the visage has a cooldown. Spell Totem can be used for a plant spell if you still want to do that.

Does pinning count towards the immobilization condition on Moment of Vulnerability too? If so, there's some really easy ways to do that with plant skills, or even another physical spell like Bone Cage. Thoughts?

I actually forgot about Enervating Nova enabling electrocution buildup. They also fixed the bug that prevented it from working with Astral Projection so that's definitely an option for a spellcasting build.

I'm personally on a crossbow and grenades build, but found Voltaic Grenade to be mostly unnecessary after a freeze and heavy stun, and not worth juggling a third status into the mix. I think it's good they're trying to allow for multiple different status to trigger the effect, but the payoff for stickling Electrocution isn't there compared to Freeze and Stun.

Pin doesn't work with Moment of Vulnerability, but that's probably because it overlaps so much with Heavy Stun. It also doesn't prevent all enemy actions like Freeze or Electrocute do, so it'd be odd for the visage to just stand there like it was hit by a Tactician.
