Background:
Joust is a gamemode fought between 2 teams of 3 on each side. The map is a single lane with the mode having an emphasis on team skirmishes, with a little taste of map macro play.
Much like Conquest, the aim of the game is to defeat the enemy Titan. In your way, stands 1 tower and 1 phoenix that you must destroy first.
To start the game, you will receive 1250 gold, and receive increase gold spooling (7 gold per second) as opposed to Conquest gold spooling (3 gold per second).
On the map, there are 4 buffs that exist:
Blue buff - There are 2 Blue buffs that will spawn on the map, one on each side (Order and Chaos). Blue provides CD and mana regen.
Red buff - This is the most important "neutral" buff on the map. To start the game, most teams will fight over control of the minion wave and in turn the red buff. Generally, the team that clears the wave first will gain pressure of red buff. First wave pressure is very important as it has a clear snowball effect on the next few minutes of the match. Red buff provides a damage over time (DOT) effect on any damage applied by the wearer of the buff.
Purple buff - This is the less important "neutral" buff on the map, it spawns in the "jungle" and is generally cleared first by the team that gets red buff pressure. Purple buff provides a stacking STR/INT buff with lifesteal.
Phantom Knight - This is the new Bull Demon King or Fire Giant equivalent in Joust, defeating it will provide a 20% penetration buff and also disable the foremost structure present on the enemies side. This jungle boss is essential for success in Joust, ensuring it is warded later in the game is always a good idea as losing this buff can be game losing.
Common Team Compositions:
1 mage + 1 guardian/warrior + 1 hunter
1 hunter + 1 guardian + 1 warrior/assassin
1 mage + 1 warrior + 1 assassin
Generally, these are the most common team compositions you will find in Joust. In 3v3 you have less teammates and must cover more weaknesses with less god slots. In turn, this results in certain compositions being much stronger than others. There are many variations of compositions you can employ, and this acts as more of a general guide. The main things you need to cover within your composition are as follows:
Wave clear, Single target damage, AOE damage, Frontline and Engage.
If your composition covers most of these things, you should find decent success.
