Do higher level spiders have higher chances for eggs than low level spiders? Is it better to find an area with lots of lower level spiders? Is using a multicannon/oldak coil cost effective? Or even possible?
Don't think it matters as far as drop rate is concerned. More so what would matter is kills/minute. You can use the cannon/coil to help in locations allowed which may possibly be all spider locations. I just used 1-2 aggression potions in the stronghold of security giant spider section right near the entrance. didn't take long at all.
