How do you feed the bulwark on Untold Legends The Warrior's Code?

You know the area where the Spiders regenerate when you run around, right? Well:

1.) You can SG (spider Glitch) there to gain levels. (It may take some time).

2.) Continuosly run around and kill the spiders. The Bulwark is easy to feed. You go in between the two tree or vine-like things, you will then see the Bulwark barely moving. A message will come up: "The Bulwark looks starved...." etc. Lure a couple of enemies over to the bulwark, really close. Kill the spiders, and feed it.
