Fight with Grade 1 Fighters

As explained in Impregnable Fortress your online rank is based on your fighters rank, you want to try and pair up that trophy with this one too if you can as it would save you a lot of time. That's the only reason why you want to fight with grade 1 fighters. Because if you have any character in your fighter freezer grade 2 or above it will affect your rank online and thus pair you up with tougher opponents.









On these raids its advised to use premium decals as they won't disappear if you were to lose so those are a good investment. These can be bought at the mushroom club in the waiting room for 50 000 coins. you can still use normal gear and normal stickers if you want but these will disappear forever if you die while on a raid. This won't count towards Material World either as the gear disappears/gets taken and doesn't get destroyed.

Other tips

Users have reported that using a weapon with blunt damage (such as a Metal Bat or Iron) has a higher chance of knocking out a fighter than any other damage type.





Using a goretastic move will always result in a death of a fighter, so don't use those (unless the enemy is 6 or more levels higher than you as it won't matter).





When you knock out a fighter in the Platform area, just take that one. Don't take chances by dying in the waiting room area. No matter how easy the opponent seems.





This is the rarest trophy in the game, and for good reason. That's because knockouts which are needed to capture a fighter are very rare. Luckily there are some ways that can help you get this trophy almost twice as fast.In order to capture a fighter, you need to knock out an enemy fighter while you are on a raid, pick up their body, and carry them back to your Train before the time runs and leave in order to confirm the capture. There isn't any special technique to do so and its mostly luck based but there are some factors that will help to increase the chance of getting a knockout.It is important to note that you can knock out more than one fighter in a single TDM Raid, but you can only capture one fighter per raid sadly.The odds of knocking an opponent unconscious are based on the difference in levels between your Fighter and theirs.If your enemy is 6 levels higher than you = impossible.4-5 levels = very rare1-3 levels = rareSame level = highest probability of capture (but still somewhat rare)NOTE: If you were not to be able this with grade 1 fighters early in the game you would have to use grade 4 or 5 fighters depending on how you work on Impregnable Fortress so please read that trophy thoroughly first.This will allow you to hold more fighters in your restroom at once so you can reset more fighters at the same time. you can also release fighters if you want instead or if you manage to get all stalls full.As you invade countless bases trying to capture their fighters, you will earn a tremendous amount of SPLithium and Kill Coins which you can use in order to upgrade your base, attract enemy players to your base (capturing fighters will help with this as well), and purchase Premium Decals from the Mushroom club.To find out how many Fighters you have Captured you can access your Player Log.To access your player log press Options () > Underworld Rolodex > My Data > Player Log > Fighter.
