When I found the Phoenix, Lua Error appeared and after that my character stopped beating with tentacle in a close combat.
This became clear by the lack of tentacle animation during a normal melee attack and by the fact that the resource does not accumulate.
Plus I checked the log later - there was no darkness damage.
