Those who study meteorology and weather science are often known for designing a numerous machines and tools that allow them to manipulate weather and storms. Some hail from places such as Weatheria, and some may simply develop these technologies on their own.
Cloud Surfing
Starting at 2nd level, you can use a Bonus Action on Your Turn to create a floating cloud beneath you that that pulls you in any direction using an air current, immediately before or after you Cast a Creation Power (Spell) of 1st level or higher. Doing so allows you to fly up to 10 feet without provoking Opportunity Attacks.
Storm Forecasting
At 6th level, you gain Resistance to lightning and thunder damage while holding your gadget. In addition, whenever you start Casting a Creation Power (Spell) of 1st level or higher that deals lightning or thunder damage, storm clouds emerge from your gadget. This eruption causes creatures of your choice that you can see within 10 feet of you to take lightning or thunder damage (choose each time this ability activates) equal to half your Tinkerer level.
At 18th level, you become immune to lightning and thunder damage while holding your gadget.
Weather Control
At 10th level, you gain the ability to create and control weather around you.
If it is raining, you can use an action to cause the rain to stop Falling or wind to change direction in a 20-foot-radius Sphere centered on you. You can end this Effect as a Bonus Action.
As an action, you can cause clouds to form in a 20-foot-radius Sphere around you and create rain and wind in that area for 1 minute. Up to 10 gallons of water will fall from this rain altogether onto whatever surface is beneath it, extinguishing any small flames, and reducing all fire damage dealt in the area by an amount equal to your intelligence modifier. The wind will disperse any fog within 20 feet of you while this Effect is active. You can also end this Effect as a Bonus Action. You can use this effect a number of times equal to your proficiency bonus until you complete a Long Rest. If you are out of uses of this feature, you may expend a creation power (spell) slot to use it again.
Thunder Counter
Starting at 14th level, when you are hit by a melee Attack, you can use your Reaction to deal thunder damage to the attacker. The damage equals your Tinkerer level. The attacker must also make a Strength saving throw against your Tinkerer creation (spell) save DC. On a failed save, the attacker is pushed in a straight line up to 20 feet away from you.
