You can carry up to two guns with you at all times. You start out with the Bad Pistol at the beginning of every run. As the name implies, the Bad Pistol's stats aren't that great and the damage is minimal. However! The Bad Pistol also costs no energy to fire, making it handy in emergencies.

It's much better than relying on the wonky melee attacks, not to mention the danger that comes with trying to get that close to enemies in the first place. Keep in mind though that you will sometimes find new weapons that cost zero energy, like the dedicated melee weapons. Go ahead and replace the Bad Pistol with these!

Having trouble early on? Try unlocking the Chest in the lobby before going into the dungeon. The chest costs a one time fee of 1000 gems to unlock, but it provides you with a common weapon to start out with at the beginning of every run.

The dungeons are host to tricky traps! The most common is your typical spike trap, but these are easy to avoid as long as you watch your footing. Beware of the colored barrels! Depending on the color, these barrels will do something differently if they're hit by either you or an enemy.

The classic red barrel explodes when it's struck, dealing around 5 damage to anything around it. Be careful around these, as you can easily kill yourself in one explosion if your shields are broken. On the flipside, you can utilize them to wipe out a lot of enemies!

Green barrels will leave behind a small cloud of poison gas. Poison gas can also naturally spawn in certain rooms, so watch out! Lingering around poison gas will sap your health away and slow your movement speed.

Blue barrels shoot out a burst of ice crystals when they're destroyed. Anything that is hit by one will freeze on the spot, disabling any movement or action. Obviously this is great for stopping problem enemies in their tracks, but be sure not to get hit by one yourself!

Grey barrels shoot out darts. These have no special effects; they just damage you normally.

If you find a gun that has the Frost prefix, use it! Frost weapons can freeze enemies (the same effect from the blue barrels) when you critically hit them. This effect is incredibly helpful during boss fights, as you can avoid crazy bullet patterns altogether if the boss is frozen. Couple this with the Knight's special ability Dual Wield, and you have a very high chance of landing critical hits.

Upon taking a portal to the next level, sometimes you're prompted with a random selection of power ups. Here's a couple we've found useful:

Increased chance of finding potions inside crates. Health potions are pretty rare by default, so you'll want all the help you can get with restoring health. This will give you a point to breaking all those random crates you come across!

Slower enemy bullets and increased pick up radius. The pick up radius is nice, but the slower enemy bullets is almost a necessity with the amount of bullets the bosses spray all over the arenas.

Immune to traps. This one's situational. This makes you immune to spikes but it does not make you immune to the barrel traps.

Chance to restore health on enemy kill. This one is pretty straight forward and can give you a nice buffer between levels.

The Rogue's special ability is a combat roll that grants them invincibility frames. Much like the frost weapons, this ability is invaluable during boss fights when things get really crazy. The Rogue costs 2000 gems, making them the cheapest hero to unlock. You should aim to unlock the Rogue as soon as possible.
