Maintenance starts at 3:50 PM, so I'll be waiting.

My combat power is increasing and I'm steadily progressing through the main stages, which is fun. I was able to get stronger by evolving my weapon with 1000 chips and 25 legendary cubes, so increasing attack power is key. Watching over 30 ads daily helps me get stronger little by little, which is appreciated. The variety of ways to get stronger, like with sub-weapons and attachments, is also a great feature.
