Phase 2
Buy monkey village and upgrade up to Jungle drums and monkey intelligence bureau. The village should be placed on the right hand side of the alchemist, when upgraded should affect both alchemist and ninja monkey. (just realised i forgot about obyron for phase 1 just place him right under the alchemist on the other side of the road. Goes to show how op ninja monkey and alchemists are.)

Place 5 wizard monkeys in range of both the alchemist and monkey village.
Slowly upgrade them towards necromancer: unstoppable army and wall of fire.
At this point you can basically afk. Dump any money you want into the hero. If you're feeling insecure you can spam Obyns abilities whenever they're up. That concludes monkey meadow. Stay tuned for the other maps.
