Using wyvern milk helps you not insta die to em cause it cancels the bleed best way to kill for me tho was 2 things large bear traps n a wooly rhino. You have the giga get trapped n the u ram into the giga from behind you can about 6000 damage per trap with a high melee rhino 🦏

Next strat is large bear traps and a Thylo trap the giga and then bleed it out make sure to come from behind tho with both starts or u will get hit

Hope this helps
