I really wish I could figure out some way to make the giant wolf spider actually useful. As far as I know, pretty much everyone has tried and pretty much everyone has given up for the time being. The giant wolf spider seems to have two main functions: stuck conditions, and it's taint-boosted melee attack. It also seems like it might like to chase the enemy. Unfortunately, there are a lot of more efficient ways of immobilizing enemies and dealing higher amounts of damage to them from melee attacks. Although the giant wolf spider does have psychic immunity. I suppose he might be a good, cheaper, zombie alternative to Sardonyx, but I'm not entirely sure...
