Oh, sorry, typo, it's 'List', not lost. Okey, hereo you go.
This boss starts to Borrow every minute, after one minute of engagement, which first borrow will be on the 2nd minute after engagement.
Borrow deals 10% max health to those who stands near when borrow starts.(325 range)
The worm will moves to a targeted raider, dealing a AoE massive damage upon reaching it. Won't target those who are within 500 range and moves at a 150 ms. If no one is within range, erupts, dealing 4.5k damage. This is considered phase 2, and it lasts for a minute too. If time's up and no eruptions occours, it erupts at current position. Ending eruption deals 2k damage.
Frostlings:
Summoned every 45 seconds, a wave consists of 6 frostling, everytime spawn 2 wave, one at the left side of the map and right side of the map. If while the worm is on the surface and noone is in it's melee range, 8 waves will be called in, 4 at the left and 4 at the right.
So this is what i think of btw, any thoughts?
