Best tactic to take down Giants at level 1 without kiting them (too much), grab a bow and a quiver packed with arrows, start loosing some arrows at the giant, as soon as you see him raise his club above his head for the homerun strike, sprint (yes sprint, running isn't fast enough

) towards him and literally under his arm as he brings it back down to earth, you will probably get some splash damage and a little stagger, but if you are quick enough you can turn and fire some more arrows into him, then repeat.
It's a little challenging until you get used to it. But it's fun playing that close to certain death.

Any bug that only happens to your corpse is null IMO, you couldn't play on as a corpse, so what difference does it make if you just spin round and fall dead (hate that spin animation, thank god for mod ;p) or take a short flight?
