• (Pistolier Only) You can fast reload your pistols by dropping the magazines and placing the guns upright in your ammo belts to the left and right.
• Ejecting or dropping a partly-spent magazine into your ammo belt will add the same magazine to the next reload (NOT RECOMMENDED, AVOID AT ALL COSTS)
• You can take attachments off enemy weapons before they dissappear and place them on your own. (for example, laser sights)
• Heart Containers give a full heal in addition to the max health bonus.
• There are different heart container rarities, base being +2.
• Friendly fire is possible and allies WILL become hostile if hit too many times.
• After a fight and when approached, some allies will ask something from you (ammo, medkit), and sometimes give an item in return.
• Allies can drop loot like enemies.
• There is a chance for a large, high-level enemy to spawn when approaching a door at the end of a level.
• There is a rare chance for a chest to spawn after killing all enemies.
• Using weapons dropped from enemies can both help save on ammo and engage in range not possible with your class.
• You can dual wield dropped enemy weapons.
• Other player ghosts can be used to revive from Ghost form, just like the player’s ghost.
• Some projectiles like Arrows(?) and Magic can be shot and destroyed mid-flight.
• Finishing the game will unlock a higher difficulty (stronger enemies/higher xp gain) as well as the Global Sun Run.—
  (Global Sun Run info in this part of the section, don’t read if you want to go in blind)
• The Global Sun Run is a different portal with 24 randomly generated levels from the last portion of the game.
• Global Sun Run has no bosses nor key-locked chests. Only stronger and higher quantity of enemies.
• Global Sun Run has three stores. First one at level 2, another one at level 10, and lastly at level 20 (someone confirm last one). None of them have locked chests or donation stands, so there’s no reason to store keys or items you only want to donate.
• Global Sun Run has no rats or wolves. It only has humanoids (snipers, rifles, smgs, magic) and the Slenderman looking guy. Your biggest worry will be getting rushed by twenty guys or getting shot from different angles.

Poison and charms stack. Meaning if the muzzle has +4 magic damage and you use a bomb charm which gives +15 damage, the enemy will receive 17 poison damage every second in the explosion, which can be refreshed by shooting at the enemy before it wears off.

Unconfirmed: it also stacks with the sun spell.
