Increasing the difficulty on Ragnarok mode

[Slayerplayer]

So, I think every boss needs an ability like Thor and Odin. 

Heimdal can blow his horn twice. Healing his soldiers one horn sound. To increase their damage - another sound of the horn. But then you need to find two different horn sound to make it epic. 

Hodur as And one can send the arrow in the sky. but size should be small so that the player is difficult to see the illuminated area. Let it lets on one arrow in three players at a time that was more artful. 

Loki give the ability to appear unexpectedly. There are several options. 
Option 1-wave Loki and tricksters may appear randomly and out of turn. 
Option 2 - Loki may receive the first wave instead of a trickster, and instead of a Wraith. 
Option 3 - Loki can teleport where he wants and when he wants to, and can disguise as a player. What do you think?

The idea noname I loved it!

Hodurs ability wont work. simply because most areas are roofed completlly.you assume that every place is without roof, but its not. it would be an instakill too when people cade in small areas and they cant jump out really when all of them try to escape at once.
