Pick up food items to heal. You have to leave or finish the level to revive dead ones and fully heal all. What's the specific trouble you're having? What chapter are you on? I'm assuming you have the starter pack guys plus one other...who is it? What level are they? --- I'm gonna go butter up my pooper with it real good!
Well my cousin hve been playing and we keep getting all the skylanders killed when we are at the very end and i was just wondering if we could revive them quicker. I know they heal a little bit if you swich them out for a while. and by the way i have the starter pack plus chop chop and i just bought bash last night.
If you get the Dark Light Crypt adventure pack it comes with a health potion item you can use on the portal to slowly regen health. If you can find him Whirlwind (extremely hard to find before he is re-released) has the soul gem ability to heal other skylanders.
