Loop Hero is all about wandering a potentially eternal loop, defeating monsters, placing cards to manipulate the game, and trying to stack the odds in the hero's favor. There is a lot for players to get to grips with when it comes to understanding the core gameplay loop, and the seemingly simple game can take dozens of hours of play to understand fully.
Loop Hero is filled with different resources players will need to gather up to expand their camp and get further into the loop, and the Orb of Expansion is both very important and very difficult to get. It can often be better to dedicate a run on the loop specifically to getting this resource, but players will need to get lucky even then.
To get the Orb of Expansion, players will need to kill more than four enemies in a single fight. This is a rare occurrence in Loop Hero and is also very risky. Engineering such a fight can be done by using a specific tile combination, but even that will only work for a limited time. By placing a Vampire Mansion tile right beside a Village, the Village will become a Ransacked Village for three turns. During those three turns, the tile will spawn four Ghouls, and the nearby Vampire Mansion will spawn a Vampire, resulting in five enemies being on the tile.
At the end of the fight, provided the player is successful, the Orb of Expansion will have a chance to drop, and the drop chance will increase as more enemies appear on the tile. This tile will only generate five monsters for the three turns that the title remains a Ransacked Village, as the Ghouls will stop spawning after it becomes a Count's Land tile.
Players will want to unlock the Herbalist's Hut and get access to potions and use every trick they can to heal during these fights. Building high evasion stats on the Rogue is a good tactic, or a health regen Warrior build can also carry the fight and heal up considerable as the hero travels the rest of the loop in between battles.
It is certainly a good idea to focus on farming the Orb of Expansion by making sure that Village and Vampire Mansion cards are in their deck before players start an Expedition, and ignoring chapter bosses such as the Lich in favor of spawning as many high enemy count tiles as they can, then leaving when they finally get the Orb of Expansion. It is even possible to make the rest of the loop as easy as possible by simply not placing any other enemy-generating tiles and focusing only on building combinations of the Vampire Mansion and Village tiles.
