Walkthrough: Sonny 2, Zone 6 (Biological/Heroic)

Another chapter in the run for the Ashes of Ashes achievement. In case you have gotten the Legend achievement now (which you should have), you can train as much as you want here. It will NOT matter because zone 7 is already unlocked with the Legend badge.

1. Metal Warden:
   Watch out for his Death Sentence spell. It is the same that The Warden from zone 1 already used and will kill the affected team member. Whether you have a strength-based Poison build or a speed-based shadow build, this fight should be easy.
   
2. The Bomb:
   Wow, this took me long to figure out. Here's what I did:
   Put ALL available points into speed (Respec if necessary), put equipment on that boosts your speed and bring the following abilites: Withdrawal (max), Agile Exposure (max), Shadow Blend (max), Toxicant Form, Leading Strike.
   Use this sequence to inflict damage: Corrosion - Toxicant Form - Shadow Blend - Agile Exposure - Withdrawal. My Bio inflicts about 29,000 damage (31k) with that combo (!), depending on your stats it might be more if you have good equipment. Mine was average because I threw away some high speed-bonus stuff.
   Fill in with Agile Exposure and Leading Strike, then repeat the whole sequence (7 turns per cycle due to the cooldown of withdrawal) until finished.
   Your teammates will also benefit from the Agile Exposure and Corrosion, making them inflict more than double damage.
3. Nostalgia:
   With the above sequence and event half decent gear, you will knock him down in no time. Bring Disrupt along, by the way, to counter his buffs.
4. The Judge:
   Same as above. Piece of cake for a good speed build Bio. Funny attack buffs has, though.
   

Having been able to kick the bombs butt after all really made my day. Yay! :)
Enjoy your victory, and move on to zone 7, which won't be so easy.
