Shadow Visual Improvements Needed

I’ve been playing it for the past week and it’s extremely fun to play in shadow but there are some holes.

Wall of Agony: Encircle: Could easily become an Abyss version becoming a circle of black tentacles swiping at enemies instead of the standard demons. There is no shadow choice for this spell at all which was sad to me because the full Shadow Warlock needs more protection than the other variants considering most of their abilities require time to do the damage since they rely on damage over time abilities the most instead of burst.

Sigil of Chaos: Sigil of Smoke: doesn’t actually produce any smoke or much of anything at all visually to let me know it’s gone off. Could you put some semi transparent tentacles on this Abyss choice as well to allow me to see when it’s working?

Sigils in General really seem to have an insane number of requirements to work just right, they are not as large as the sacred ground of the paladin, the curses of the necromancer, or the mystic circles of the spirit born. In addition we have to kill 8+ demons at least right inside the boundaries (rather than nearby) to cause their functions to trigger. Can we make these sigils suck the enemies into their boundaries and slow them similarly to the chain spells and increase their size?

Error in Design: Molten Bomb: Cluster Bomb: Is entirely too slow. I understand you’d like to make it shadowy and different but it shouldn’t be slower. It’s animation takes too long to do enough damage closer to the Warlock before the enemies have a chance to reach the player character.

Error in Design: Ruptured Abyss explodes even when other warlocks nearby have them down when one casts it again, But the each instance of the Rune Dark Prison cast by the Rune system does not react to the explosion cast of the main Dark Prison spell from any warlock. This allows enemies to slip through because only one Rune prison causes one prison of enemies to explode and none of the others are set off.

I hope you guys take these suggestions seriously! I think if you do it will make this class more well rounded.
