Sunshine, Nightfall, Snow, Rain.

These 4 weather conditions are caused by certain weapon charge attacks, or just occur naturally. Usually, a weapon that causes a weather condition will not benefit from that specific weather condition.

Weather conditions do not appear in Lockdown, and will not be a balancing issue there since they will not exist in PvP; only in the clockworks or missions.

***Sunshine***

Sunshine's visual effect looks similar to when you are in Haven: In the top middle to top left corner of your screen, there will be beams of orange light.

Sunshine is caused by Sudaruska's charge attack and has a duration of 30 seconds.

Sunshine increases weapon and monster chance to cause fire to 130%, and reduces weapon and monster chance to cause freeze to 70%.
*****Here is an example of what I mean. Furious Flamberge has a 1 in 16 chance to cause fire. In sunshine, it now has a 1.3 in 16 chance to cause fire. I don't mean "30% extra", I mean "130% of the original chance" or "70% of the original chance".

Special Effects: Valkyrie Armor's negative fire resistance is not in effect in sunshine, reducing fire's strength against it and keeping the "holy" armor (holy = sunshine) aspect to it.

***Snow***

Snow's visual effect is comparable to that of freeze-themed levels in the clockworks.

Snow is caused by Triglav's charge attack and has a duration of 30 seconds. This is the only weapon that benefits from its own weather condition.

Snow increases weapon and monster chance to cause freeze to 130%, and reduces weapon and monster chance to cause fire to 70%.

***Nightfall***

I am not sure what Nightfall's visual effect would look like or what I should compare it to.

Nightfall is caused by Graviton Vortex and has a duration of 30 seconds.

Nightfall increases weapon and monster chance to cause curse, self-inflicted curse, and sleep to 130% and has no negative effect.

Special effects: Gran Faust's charge time becomes comparable to Divine Avenger's. Divine Avenger's charge time becomes comparable to Gran Faust's. Chaos Armor's negative poison, freeze, and curse resistance becomes positive poison, freeze, and curse resistance in Nightfall.

***Rain***

Rain's visual effect is comparable to the effect created by the sprinkler system in the new recruit missions with Rhendon.

Rain is caused by Neutralizer's charge attack and has a duration of 30 seconds.

Rain increases weapon and monster chance to cause shock to 130%, and reduces weapon and monster chance to cause poison to 70%.

Special effects: Leviathan Blade will truly rain down upon its foes like the water from a tidal wave as its description says, slightly increasing its charge attack's range.

Weather conditions may also occur naturally in the clockworks or in missions. These weather effects cannot be altered or changed if they occur naturally.

One weather condition can replace another if the weather condition did not occur naturally.

Weather conditions cannot be caused by these weapon charge attacks unless the player is holding a Weather Stone trinket.

Weather Stone, 5 star trinket. Description: "Allows the player to cause weather conditions with certain weapons while in the clockworks or on a mission." There will also be added flavor text, I am not good at creating flavor text.

Real life reasoning behind some of the effects:

1. Sunshine = heat = should make it more difficult to freeze things. Sunshine can cause droughts, which can lead to fire.

2. Snow appears in cold weather conditions, and in cold weather conditions, things freeze easier. Snow significantly reduces wildfires.

3. Nightfall. Witches in real life likely prefer the night time to cast their dark magics = more curse? No true need for a negative effect.

4. Rain = water = a good conductor = shock. No, rain does not help get rid of fires. There should NOT be a reduced chance of fire effect, since rain and floods tend to cause wild fires due to the shock factor and we already have a negative fire effect from snow :). Rain also spreads disease, so a reduced chance of poison is illogical. Regardless, think of rain washing away poisons? Err....

In game reasoning for these effects:

1. Sudaruska and Triglav currently are great for their charge attack. They are both slower and deal less neutral damage than GF and DA with normal attacks, but I think this could be made up without damage buffs. A weather condition that can be useful utility-wise will help balance them.

2. Graviton Vortex is not nearly as useful as Electron Vortex due to Electron's chance to shock and cancel knockback as these weapons are used for utility and not damage. Graviton Vortex causing Nightfall and increasing the chance to cause curse can be a great added effect to gather up monsters with a Graviton then have a teammate unleash a GF charge attack inside of the cluttered group of monsters sucked in.

3. Neutralizer is just Neutralizer, 80% of Spiral Knights are unaware of its existance...... (80% is accurate, forum goers / wiki users are the minority of this game). It deserves something cool. It looks blue, and blue = water, so rain -.- sorry, not much of an explanation RP-wise here.

4. These should not be overpowered. Look at my example earlier, in Sunshine a Furious Flamberge will rise from a 1 in 16 chance to fire to a 1.3 in 16 chance to cause fire. 130% of its original chance, not 30% added chance. It will make only a slight difference, although it may help very much defensive-wise against certain status themed monsters while being a hindrance against other status themed monsters. Keep in mind that some of these status themed stratums, like freeze-themed levels, tend to already have a natural occuring weather condition which cannot be replaced.

They also demand an entire trinket slot to be used for the Weather Stone trinket.
