I've switched to using a tiger now. Crabs get stuck too easy with the Warriors getting under it.
The maneuverability and speed of the tiger's attack is great. Wear plate, have monkey, eat damage reducing foods and a med kit if things get real hairy.
Jump in middle of them to kill archers fast
Jump out, run out to kite them
Turn to face them, just walk backwards, swiping.
Time the Warriors attacks, you have time to step in, swipe, step back, before being hit.
Using a crab, can still be done, however, they go through stam like crazy on high levels, feed it shrunken head stew for sure.
