How the Warden could combat small spaces, combat walls and be more scary

Basically the idea would be that if the warden were mad at you, and can't reach you, maybe it could unleash 2 different types of mobs; Skulkified-spider and the soul. The soul would clip through walls like a vex, and if it were to hit you, it would give you the darkness effect. The Sculkified-Spider would be a fungus-infested spider with sculk on its body. It could see and can locate players. Every time it hits you, it alerts the Warden where you are. They could spawn with the warden, or even just sit in the sculk biome, and they could climb walls. Finally, they would be faster and stronger than a normal spider, and would even twitch their head to give more of a fear factor.
