Woo Hoo! Update (below game description) says theres going to be an update during the summer! Just letting all the people who don't read the updates out there know that! :D
The character's like a supersoldier...he's got 9 lives, he can double jump, has the force to move jewels, and armed with a pixel minigun...yep, there's no stopping him.
Actually, a spy would do better with a knife, where she could then sneak up behind enemies and backstab them. I mean, a timed bomb? That's a big no-no in stealth.
Here's a tip for everyone: If one of your units is low on HP, upgrade them with stars to a multiple of 5 (5 stars, 10 stars, etc.) This will recover their HP to the max. I keep all my units with 4 upgrade stars, 9 upgrade stars, etc. so if there almost dead, I just put in an extra star and full HP!
This is an add on to my previous comment. My final stats were: Maxed out H Attack, H Defend, L Attack, L Defend. Maxed out Poisoned Death, Poison, Poisonous Wave, and Paralyze. Spell Level 50 Life, Spell Level 51 Mana, and Spell Level 10 Basic Damage. Hope this helped you get the badges!
Here's what to do for the badges. Choose Poison Water as your starting clan, and start out by upgrading H Attack and L Defend. Keep training, and start spending skill points on life, mana, and basic damage. Don't bother learning Higher Level Magics, just learn Poisonous Wave first, Poison second, and then Paralyze. Upgrade them to max, then upgrade H Attack, H Defend, H Defend, and L Defend to max. Make sure your basic damage is maxed as well. From here on, keep upgrading mana and life. Use Poisonous Wave to poison your enemy, and use Paralyze to stun them. With enough mana, you should be able to finish your enemy off eventually. This is optional, but equip Poisoned Death if it helps.
