Something's up

I just took Blast Arrow Castle with almost no problems what so ever o.o I have skeleton spawners for harvesting unlimited bones and arrows. There are still some areas that I have missed. I plan to return and loot those areas once I've finished some housekeeping tasks. Lots of skeleton spawners and I did hear a blaze. Skeletons are the problem because of their ranged attacks. Blazes are nothing if you have Fire Resistance ^_^ You just need to keep out of their melee range.
