The fight

Mechanics

It swaps between ranged and magic every three attacks, one every 6 ticks.

After every five attacks it fires a lightning ball that splits into two currents. They chase you, hit up to about 18 and stun you for 4 ticks. The special doesn't line up with the style swap, so time your prayer switches. It's immune to poison.
