Azkor Survival event
In this event you can only use Chaos units and Azkor is mandatory to use.
As last survival event shoved tanky units that can deal with multiple enemies are the best for clearing waves. In theory summoners should be good, but for chaos they are too squishy. Exception is for Corrodius who can flood the field and his passive gives so much needed mobility for chaos units. Abraxas can give you one free turn but that is, his summons will die and unless you can pickup refresh bonus he's gonna die too without doing much else.
Some tips from my gameplay:
- Keep you units close together for Wrask shields and Rotbone heals.
- If you have your actives, you can wait a turn for enemies to come to you instead of breaking your formation.
- Always clear waves before rarity upgrade or you will lose a lot of health or units against one upgrade higher enemies.
- You can wait for Bomb pickup and only use it when more enemies around. It becomes stronger as game progresses.
- For rank upgrade you don't need to clear genestealers ambush tokens, you just need to don't have active enemies on field.
