Tip to tanking BH SoT without barb

Staryu - Dreamweaver

1) Watch normal chat.
2) When he says congratulations. Spark resist or absolute domain.
3) Rinse and repeat until boss dies.

You still need to be able to tank boss when he buffs though. I've done it with 6.7k hp. His buffed normal attacks hit around 6k without bb and with 9k def.

If you can't find a barb and have no high hp tank, your best bet is to find a veno to purge his attack buff.
