Simple really. Don't go trolling, don't just stand around, don't intentionally hinder other players.

Send some stickers, react to other players. Have fun.

You might have seen other players being affected by your attacks or getting kicked around yourself, this is called tripping and really annoying, to prevent it you should equip a Shock Absorber (Shockproof) or Flinch Free (Brace) decoration. Shock Absorber keeps you from hitting others or getting hit while Flinch Free only protects you but can stop some reactions to very weak monster attacks (really. look it up, it's not worth much)

When someone has mounted the monster everyone else does severely reduced damage. So use that time to sharpen, re-apply buffs, heal or prepare a strong attack to release once it's down.

You can craft more heals, traps or pods simply by having the ingredients on hand. I always carry 5 Mandragora and Catalyst to make more Max Potions.

There are traps everywhere in the world that can significantly speed up hunts. Sometimes it's even possible to stun a fleeing monster. Hint: Lagiacrus

Don't hit a sleeping monster! The first hit on a sleeping monster deals double damage, the so called "wake-up". And when the monster is sleeping you can place bombs to stack up some damage or heal/sharpen while others prepare bombs. Good options to deal the wake-up are True Charge Slash with the Great Sword or a charged attack with the Hammer. Any charged attack that deals it's damage in a single instant.

You can tell a monster is falling asleep by listening to the music, it will fade out and the monster will lie down.

When you join any quest the goal is to hunt a specific monster. So doing anything else is just wasting everyone's time. If you want to sightsee play alone :D

This includes focusing on a single monster in a quest with multiple targets. Simply open the map, look where the other players are and help. Monsters in multiplayer are more aggressive and have more health, you should never fight alone.

You might think "wow healing is so good, I'll just sit back and heal my team"
That's not a good idea.

• you do no damage
  
• you don't distract the monster
  
• you make teammates rely on your heals - if you can't heal they might die

It's just not a fun or effecfive strategy, you are more helpful in the fight.

These things are awesome, any time the monster is leaving the area just shoot it with this and you get another minute in the ring.

Lifepowder or Dust of Life. Occasionally healing everyone makes the hunt much safer overall.

Everyone does more damage yay!

You know how busted these things are when playing alone right? Now picture 4 hunters wailing on a downed monster, yeah. And as a bonus you can use them to save other players that have been grabbed.

Again: stunning the monster while 4 players are hitting it is awesome! Capturing is good to get hunts over faster, especially when you already used 2/3 faints.

The primary use of bombs are to be used when you wake a sleeping monster, if everyone places them that deals a lot of damage. You can also pick them up and roll them, fun.

To clarify: I am talking about using a Focus Strike on a wound. Hitting wounds normally is fine!
Some weapons get more out of wounds than others.

• Sword & Shield
  
• Dual Blades
  
• Lance
  
• Gunlance
  
• Light Bowgun
  
• Heavy Bowgun
  
• Bow

If your weapon is on this list, kindly leave wounds for others.

• Great Sword
  
• Hammer
  
• Hunting Horn
  
• Switch Axe

Great Sword gets a fast way to TCS, Hammer can charge while attacking, Hunting Horn can stack some Notes and Switch Axe can trigger a fast FRS or activate Power Axe.

• Long Sword
  
• Charge Blade
  
• Insect Glaive

Long Sword gets a Spirit level per wound and can combo into spirit roundhouse, Charge Blade can activate Savage Axe mode and Insect Glaive gets Triple Buff instantly.

Please let them take wounds, it really makes a difference.

When the monster is fleeing popping a wound can get them to stagger and stay longer, especially blue (tempered) wounds do this. So when you have the opportunity go for it!

After the monster used a particularly strong attack you can attack a part of its body (usually the head) as if it were a wound, but only for a moment. A good example of this is Rey Dau after he uses his Laser/Zap attack he opens his head and horns which is then a weakpoint.

Since these are so fleeting everyone can use them.

These weapons are particularly suited to MP hunts. In general lighter weapons that sheath faster are better.
SnS can famously use items while the weapon is unsheathed, allowing users to heal teammates or use traps really fast.
Hammer can stun the monster better than any other weapon creating openings for everyone to do damage.
The buffing weapon, do i need to explain this?
A fast sheath speed combined with being ranged means players can buff or heal safely. And there are ammo types exclusively for teamwork.

Consider these effects as they are much stronger in a group.

These skills can be helpful in multiplayer.
They are only suggestions, use your own judgement on what you think is needed.

I've touched on this in the first section, this skill stops tripping completely.

A good teammate is one that doesn't faint. This is the best defensive skill. Heroics, Speed Eating, Evade Extender and Evade Window are also good. Use "Resistance" skills (stun, poison etc.) when applicable.

Wide Range is an Armor Skill that "Allows the effects of certain items to also affect nearby allies", in caveman speak: YOU HEAL - WE HEAL. Combine with Free Meal and go to slurp town on those mega potions.

These are the main multiplayer skills. Almost every skill is good situationally, check out the comments for what other players like.
