With the help of this guide you can grind weaker enemy to make yourself as stronger as possible before run into difficult enemy that you can't handle yet, then progress as far as you can.
- Meat icon: Weak enemies, you should aim for those first.
- Stars icon: Strong enemies, the more star they have, the harder to defeat them. But them also drop Legendary and Epic Relics.
- FactionIcon: Indicates the most threatening enemy in a squad. For example Brutus with 4 hypogeans will mark as Mauler squad.
The general rules is to defeat weak ones first, then head for star enemies.
It's worth noting that there's a 2-star enemy behind the yellow sun portal, you need to defeat it to progress, this is the first choke point.
3-star enemies are way harder than others, if you didn't get good Relics (Firebringer etc) after clear all 1-star and 2-star enemies, it will be a difficult fight at the end.
