What does Alter Environment do?
Note: This is a very powerful ability at higher levels, and any significant use of Alter Environment that would affect a significant area will require Staff oversight or approval before performing - this approval can be in the moment or acquired beforehand through a ticket. Reckless or negligent use of this power in ways that cause great collateral damage or harm to innocents may be considered sufficient to damage your grounding in the Light Side of the Force. Permanent altering of a landscape through terraforming efforts or invoking natural disaster level applications of the power requires DM-level approval and will generally be limited to non-standard (event) areas unless or until module changes become easier to implement, if at all.
No Points: You cannot use this power. It is a Rare ability.
1 Point: You have begun to tap into the flow of the Force in nature to become in tune with the planet around you. You can sense and predict weather patterns, and are able to affect minor aspects of local weather. Doing anything actively with this ability at this level takes concentration. You can influence the air to create brief breezes or gusts of weak wind, alter the temperature and humidity in an area by small amounts (~+/-15 degrees F, 9 degrees C), and dispel or redirect buildups of electrical charge in the air to protect against natural lightning strikes.
2 Points: Your attunement to the natural world is deepening. You can manipulate air pressure more heavily to create steady or whipping winds, and lower or raise the air pressure in an area to disorient opponents. You can alter the temperature by a greater degree (~+/-35 degrees F, 20 degrees C), attempt to manipulate the moisture in the air sufficiently to create fog and mist (potentially inhibiting fires) or dispel them, and even generate localized tremors in the earth. With concentration, you can create mild weather events like light to medium precipitation (rain, snow, sleet, hail), temporarily halt the flow of streams and small rivers to cause localized flooding, and affect the movement of cloud cover.
3 Points: You are in tune with the world around you. The wind blows at your request, the sky sends rain when you beckon it, and the earth will quake and rend itself open should you ask the stone for aid. With concentration you can create and manipulate weather events of notable strength: heavy rain, driving winds, even thunder and lightning (although you cannot direct where this lightning may strike short of making effort to /not/ allow it to strike particular targets). When creating tremors and earthquakes, they are still localized within a particular area, but you can now bid the earth to split open and create small fissures and difficult terrain to hinder your foes. Your control over temperature and humidity is significant now, allowing you to raise or lower the temperature to scorching or bone-chilling levels (~+/-70 degrees F, 40 degrees C) with concentration - though lighter levels of manipulation take less effort for you now. You can almost entirely vacate the air from a moderate area, making breathing difficult, or increase the pressure significantly and cause eardrums to burst.
3☆ (Mastery): You are truly one with nature. Tornadoes, tidal waves, earthquakes, violent lightning storms, you can weave the natural world around you as you require. You can now even summon individual lightning strikes to smite a target, though small targets such as an individual human might be difficult. You cannot achieve planet-wide effects.
