If there is any OG/OP mages that can solo Elite Rahab / Deal crazzy damage on bosses I would like to know your secret, cause it looks like I am dealing 0 damage with Kraken items. (Never used Kraken before and I am a NEWBIE TOO)

Recently was able to purchase my first ever Kraken gear for a mage and have no clue how to use it, when it comes to killing some bosses.

Kraken Gun, Kraken Helm, Kraken Armor, Kraken Belt, Kraken Amulet + using Beast Helm, Killing ring, and Combat 85 braclet.

So, if you don't mind can you please explain what should I do in order to deal MAX OP damage, cause as for now it looks like i have 0 damage when it comes to bosses. I proc my Kraken weapon and deal 0 damage.

If you have advice towards Mage build Including PET and Equipment build vs Bosses, I would much appreciate it! Ty
