Alliance Events

Alliance Events allow your alliance to work together and beat the boss together. While each boss has its own tricks and traps, there are some general principles to understanding how these events work.

### Waves

Each boss has 8 waves. That is to say, once you have defeated the Wave 1 version of a boss, your alliance will now be facing the Wave 2 version. And so on. Each time a boss wave is defeated, all your alliance members get an Alliance progression reward. Typically, the Wave 2-4 rewards are the three covers of a 3\* character, Wave 5-7 are the three covers of a 4\* characters, and Wave 8 is a Legendary Token.

The alliance event begins with the boss unlocked. When he's unlocked, all subnodes are locked. The boss unlocks in one of three ways:

1. Someone in your alliance defeated the boss for the wave, moving you all up to the next wave. (This unlocks him for everyone in your alliance)
2. You have beaten a subnode
3. 8 hours has passed since the last time you played against the boss.

### Time Slots

Typically, each alliance event begins on a Thursday at noon EST. This begins a series of 8-hour blocks (Noon-8pm, 8pm-4am, and then 4am-noon). These blocks run from noon on Thursday through Sunday (ending at ??:?? EST on Sunday, so the last time slice is short) There are subnodes that are available to be beaten ONCE during each time slice, and then they are locked (if you fail to beat the computer, you can try again). Each subnode has an essential character. Unlike a traditional essential character requirement, you can fulfill the requirement using ANY character with the same name (so a Venom requirement can be met with either of the 4\* options or the 1\* option).

Once the subnode is played, it will unlock the boss if it is not yet unlocked. While the boss is unlocked, all subnodes are locked (so you can only play the boss). When you play the boss - win or lose - you unlock the subnodes (that have not yet been beaten in this time slice) and relock the boss. Any points that you acquired in that game are added in to both your score as well as the alliance score.

As the time slots progress, so will the difficulty of the computer's team.

### Efficient Playing

If you want to maximize your score, there are two things to consider.

**When to Start** - Early waves of the boss have lower health, so it's possible for a well-organized alliance to defeat the wave with each player hitting the boss a minimal number of times. Typically, both the Wave 1 and Wave 2 bosses can be defeated with less than 20 successful attacks, which means if everyone in the alliance attacks each boss once, the wave will update (and therefore unlock for all players) and allow everyone to attack again, without yet completing any of the subnodes. The reason to do this is so that when you do the subnodes, the boss value when you unlock it is as high as possible. So you want to start with the boss in the highest possible wave you can reasonably expect from your alliance. To that end, the following table gives you an approximation of how many full-defeats of a boss each wave typically requires (note - alliance events with 2 boss battles, like Sinister Six, follow a close but somewhat different model)

**Event Play** - once you have started playing, your goal becomes to defeat the boss 6 times once every 8 hours. So your default strategy should be, once you've defeated the boss for the last time in the first time slot. The default approach should be to wait the 8 hours for the boss to unlock, then defeat the boss, play a subnode, and repeat until you've completed all subnodes and the boss after each subnode (with a standard one-boss event, that will mean you'll have done the boss 6 times and each of the 5 subnodes).

This approach hits a little bit of a hiccup when the boss wave is defeated. At that point, you gain the ability to attack the new boss wave. If you had not yet completed the subnodes of the current time slice, it is easy, you attack the boss now, do each subnode and the boss with each of those, and get 6 boss hits taken care of. On the other hand, if you already cleared the subnodes, you have to make a choice - either let the new wave boss sit until the time slice changes OR attack the new wave boss now and reset your 8-hour waiting period.
