beating the da ra lie (something like that)

[K_I_R_E_E_K]

Multi hit weapons, either a good slicer or a good sword, avoiding attacks with a hucast is recomended if you thing the battle is going to last a long time.

That's basicly it, you may use a gun to make an extra damage, but once he grabs to the raft, kill him with a sword, remember that he attacks with the tentacles very fast, so time your attacks correctly.
