Army of Ruin

These achievements for reaching Minute 30 are some of the toughest in the game. Unlike Vampire Survivors, this game is not so easy to become incredibly overpowered and unstoppable. The 25-minute mark is where things start to get pretty crazy, and even on my successful runs, I very quickly got overwhelmed and destroyed by 35 minutes (unlike Vampire Survivors, where it seems like you can just let your controller idle indefinitely and you'll never die once you're set up).

After a bunch of trial and error, I have put together a list of what I feel are the most critical trinkets for success. In my opinion the weapons aren't strictly as crucial as these trinkets, but obviously some weapons are much better than others, so I'll cover them second. Note that, if you don't have one of the ones I list below, just search the achievement list for its same name to unlock it. 

Trinkets
 

• Forbidden Sword (light) - useless until it's maxed, but once it's maxed it's an absolute game changer, and it feels like it practically guarantees victory. I always have this trinket marked as a favorite
• Magnifier (earth) - size matters in this game, because when the horde gets huge, it's way too easy to get overwhelmed. Weapons like Wolf's Fang that are very localized damage suddenly cover a huge part of the screen, and with six weapons in capacity, you'll notice your attacks just cover everything on screen
• Silver Bullet (wind) - crowd control is the name of the game as you get deep into runs, and this trinket is amazing for allowing you to stay on the move or just keep a safe area around you
• Leather Bracer (ice) - this is a little dependent on your weapons, but it's pretty much guaranteed to affect at least three of your weapons, and will have your huge weapons firing off way more often

Those are the key ones I always go for. Some other honorable mentions as ones I really like to use, and help out for the long runs. Pick ones that help evolve your weapons. 
 

• Shackles (earth) - this significantly helps with crowd control, especially on Forge and Shrine where there are some fast moving enemies
• Wristband of Grudge (wind) - if you do happen to take damage, especially while still rounding out your build, this over doubles your damage, which is massive to help get out of a jam
• Dragon's Heart (fire) - an extra 50% damage is nice, and there aren't many fire elements I like
• Sacred Effigy (dark) - basically the equivalent of 30% more damage, but it's a noticeable difference

Those are my main ones, and I ensure to get at least three from the top list, and at least one or two from the second list. There's a decent chance your sixth one will just be a bad RNG one, or one that you use to fill out the elements needed to evolve your weapons.

As for weapons, these are my top ones. Some aren't great by themselves, but once evolved (and with will Projectiles upgraded, or with the Magnifier and Leather Bracers) they are very good.

Weapons
 

• Wolf's Fang - extremely high damage, and with Magnifier it can cover half of the screen. Add on two Projectiles and it hits three times, plus the Fire Rate increases to make it even more frequent
• Serrated Spears - Area and Projectiles plus knockback make these things constantly clear an unstoppable path in front of you
• Storm Javelin - its evolution is amazing for crowd control, and with Magnifier its pools will cover the entire screen
• Mystical Firecracker - excellent knockback and good damage. Again, can cover the screen with Magnifier
• Whirlwind Axe - evolved and with the Fire Rate increases, these things will be everywhere doing tons of damage at mid and long range
• Blood Wing - great screen-covering projectiles, and its evolution adds great knockback
• Cupid's Arrow/Bronze Starfish - these are the starting weapons of two additional characters you can unlock, Tisha and Neptune. These weapons start off slow, but evolved and with Projectiles upgrades and high Fire Rate, these things will be everywhere. At the end of my successful runs, these weapons were always the two highest DPS weapons in my runs

Ideally, you want a mix between localized damage around you and then damage out around the screen at random enemies. I found that, with the trinkets above, I could make most weapons work as long as there was a variety in their range.

Lastly, here are some weapons I found to be terrible at the later parts of runs:
 

• Toxic Stench - amazing for the first few waves for clearing enemies and leveling fast, but drops off so fast by the middle of a run that it's virtually useless
• Golden Trident - way too many gaps in its fire area to be helpful for big mobs
• Magical Staff - really bad after the first third of so of a run. Definitely don't waste a slot here
• Throwing Axe - not enough damage and not enough time on screen. Not worth it
• Crawling Root - largely wasted shots that just spread too much to really have much of an impact

Worst case, you can always grind out more money to increase your Upgrades to help out more. Damage should be at 10, as should Size and Fire Rate. Experience should also be at 10 to level up quickly, and having high Luck and Pickup Range are helpful too for getting the most levels and upgrades you can.
