Sonny wasn't all that hard, especially as an assassin. The only abilities I use at all were Iron Skin, Regeneration, Intervention, and Smash. Made my ring be Quick Attack X1, Suppression X1, Iron Skin (lvl2-4) X1, Intervention X1, and the rest Smash lvl 5. Just use Intervention on your ally, and then use Iron Skin on yourself. Iron Skin at a high enough level makes all melee attacks 1 damage, and it gives you more HP. When Iron Skin has 1 turn left, use Suppression, and then when that has 1 turn left, use Iron Skin. Smash in between, and then use Intervention on your ally if necessary. Takes a while, but with lucky Smashes, you can make the final bosses use up a lot of their Focus fast.
on sinjid SOTW you can't use this but on most games you can
to find a number everything is a multiple of 8 so if you have 10 strength on any game first scan 80, then change it and x8 scan again. You should get 1-4 numbers just copy them down and change the value to whatever you want (must be multiple of 8 EX 888888888888888)
but before you do all that you have to click the top left button looks like a computer then click windows list and find your window (EX 00001380 - Sonny|Armor Games - Windows Internet Explorer)
