Chrono Trigger (NDS): [Optional] Boss (Queen Zeal & Mammon Machine)

Its Side-quest Time! Black Omen - Grand Finale Pt.1: So its three bosses back to back with no time in between to heal or change party members.

Queen Zeal: She's easy if you use Alya's Dino Tail and Frog's Frog Squash since she will be using Halation constantly.
Mammon Machine: The odd part of this fight is every time you attack with a physical its defense goes up and every time you attack with magic it will raise its attack. Go all out with magic attacks, since its attacks wont' do that much damage to your party.
Queen Zeal: ...She looked better human. In this battle you have a choice to charm some of the best armor at this point. If your not interested go all out on the head and AVOID attacking the hands. Note: Use Mega elixirs when in trouble
