Doomsdays

This has a description of what Doom is and has a list of all of the Doomsdays currently in the mod.

Doom
Doom is the mod's "mana" or "special" bar. It is used for specific weapon abilities, like shooting fireballs or blocking specific damage types, as well as for each weapon's built-in special which I've named Doomsdays (though in the mod they are only referred by the various Doomsday subtypes).

You gain Doom by playing normally, running around doing things that a person does in Minecraft, but you can also gain Doom faster by attacking enemies and even taking damage. However, if you die your Doom is either partially removed or fully emptied (depending on difficulty). You can also increase your maximum Doom amount by using an item called Doom Consume. On use, this increases your Doom limit by a healthy 100 points, allowing you to use even more Doomsdays for longer periods of time.

Doomsdays
To use a Doomsday, you can hit the R key (or whatever you set it as) while holding a weapon with a Doomsday. To activate armour-based Doomsdays, you need to wear the full set and use the Doomsday hotkey while holding nothing in your hand. Doomsdays, though stronger, also inflict a global cooldown on your Doom, not allowing you to use any other Doomsdays or Doom abilities until it is done. You can use the Cooldown Defuse item to remove part or all of the cooldown if waiting isn't your thing. Weapon abilities that are not Doomsdays, such as ones that shoot single projectiles and such, have short weapon dependent cooldowns usually around 5 or 10 ticks so that spam clicking is possible but has reduced effectiveness.

The various types of Doomsdays are: Influence, Overflow, Crisis, World Shaper, and Combination. Generally, Influence Doomsdays are the easiest to use as they require the least amount of Doom and have relatively low cooldowns. Overflow will usualy be an extended Doomsday and its full cost and cooldown are dependent on how long you allow it to be used. Crisis Doomsdays will be more effective at lower health levels and are generally instantaneous. World Shaper Doomsdays disrupt or destroy the terrain around you, either altering the blocks or entities or generating new terrain from thin air. Combination Doomsdays are just that: a Combination of two Doomsdays, combining their effects into one much stronger Doomsday. Keep in mind you need a lot of Doom to use these for a long period of time as using the two prerequisites and then sustaining the Combination Doomsday takes a lot.

Doomsdays have a chance for a Crucial Moment, which gives slightly amplified effects to that Doomsday. If it is an extended Doomsday, the particular iteration that had the Crucial Moment will have the amplified effects, not the entire thing. Along with Crucial Moments, Doomsdays may also Backlash, which can only happen when the Doomsday is initially used; Backlashes cannot occur multiple times on an extended Doomsday. When a Doomsday backlashes, it usually applies a negative effect to the user, with the effects being related to the Doomsday's normal effects. It will also inflict one-third of the normal Doomsday cost and cooldown to the user. Influence has a normal chance to Backlash whereas Overflow and World Shaper have a higher chance and Crisis has the highest. Combination Doomsdays have no chance to Backlash. Harder difficulties also increase Backlash chance.

For any extended Doomsday, Doomsdays that last longer than one tick or are not instant can be stopped by sneaking for a second. Extended Doomsdays are the key to using Combination Doomsdays as Instant Doomsdays need to be used while an extended one is in effect to combine them. There are only a few Combinations that are currently possible; more may be added at some point.

Some weapons will have two Doomsdays, such as the Celestial Aegis. If a weapon has two Doomsdays, they can generally be combined into a Combination Doomsday. The first listed one in the description will be the one that activates on normal special use, the second listed will be activated while sneaking with special use.

Doomsday cost scales with difficulty. For example, Decay's cost is 40 on Hard, 27 on Normal, 20 on Easy, and 1 on Peaceful. Doomsday cooldown also scales with difficulty; Decay's cooldown is 20 on Hard, 15 on Normal, 10 on Easy, and 0 on Peaceful.
