What would you like to see?
A boss that is a cooler version of argarok or maybe a wizard person thing.
Any certain items you'd like to use against the boss?
Arrows, sword, bombs???
How much damage should his attacks cause?
alot
maybe he could be a form of gannon
Should the boss follow the three hit / five hit pattern?
No, it should be even more, because the last boss fight should be intense.
