(pardon the delay, work issues) also markdown hates me (pardon the delay, work issues)

Regular feats

its going to be

• 2nd level Kinetic Activation, its use magic item with your element, even prepare a staff (charges half level)
• 6th level counter element - its counter spell/effect as long as it has your elements reaction, no use limit
• at the 11th level you can change change an impulse to another at prep leading to at 14th being able to swap on a 10 min break

impulses

are feats but they are restricted to one you have a gate for

• wood has some decent healing and deals (positive/Vitality
• earth has a way to make you into a walking tank with armor in earth a first level. AC+4 for 1 action that lasts 10 min replacing your light armor (it and other ones that replace armor automatically use your highest armor number)
• burning jet is a 1st level fire that has you "jump" with fire, upgrading at 10th level to being able to leap and not fall, a hover flight (2 actions)
• Magnetic pinions 3 actions from metal... this one im just going to copy in, its also overflow

Small pieces of metal fly from you, propelled with magnetism at great velocity. Make ranged impulse attack rolls against up to three creatures within 60 feet of you; you gain a +1 circumstance bonus to your attack roll against any target wearing metal armor or made of metal. All three attacks count toward your multiple attack penalty, but it doesn’t increase until after all the attacks. The metal pieces deal 1d4 bludgeoning damage and 1d4 piercing damage on a hit (or double damage on a critical hit). Level (+2) Each type of damage increases by 1d4.

Oh I thought of another one, any fun fluff/only useful for a very specific occasion spells like Personal Rain Cloud
