Build Description
1. One seedbomb in each direction, by each core. If spores are too squishy you can trade them for lightning auras instead.
2. The Krakon Spawns North and sometimes it can agro north towers, so you could place an Ogre minion wall as an extra procaution up there.
Demon Lord has a random spawn. Normally he can be ignored if you can kill the Dragon fast enough.
