Time is of the essence so I want to include each vocations responsibility regarding killing Urmahlullu after the update (Note: I did get help from the players of my world to ensure quality thank you so much to Smuu and Sore Surer)
For Knights: Winterblade is best or you can do a Gnome Sword. For Axes: Cobra Axe while using the spell Utito.
What Knights can do to help is to firstly walk Urma to a spot where he switches targets as he will, never walk to another player ^ or < of TP and magic walling v of the TP. If 2 people block the boss (EK/RP) it can be in any corner. Please note during the end of 3rd stage if there's no RP, you can also create a magic wall ensuring that the boss sits in place to be beamed. You can't just follow 4th form around the room because it will go back to 3rd form it must be trapped and go FULL ATTACK on it. 2nd stage and 4th form of boss is most demanding as it needs to be killed within a minute. After they do this they use the spell Utito to ensure proper damage.
For Paladins they should help be a side tank to keep it from moving. Paladins typically bring Infernal Bolts or Spectral Bolts (got this information from players) and Sudden Death Runes while using mas san and san.
For Mages Sudden Death Runes andIcicles (Only on Wisdom of Urmahlullu) + Waves. Ice should be used on Wisdom as shes immune to death then.
- Wisdom of Urmahlullu is the one where mages use icicles as it's -100% death and -100% fire all others mages and paladins will use spells and sudden death runes.
