Path of burning steppes: solar kills and picking up firesprites build up a heat charge meter, heat charge buffs solar dmg and resistance to stasis slow/freeze, if frozen instantly breakout releasing a solar explosion and can manually be activated by using grenade ability
Max heat meter is strong enough to delete red bars and chunk tanky yellow bars in legend-master pve content, strong enough to break shields and a bit of health in pvp but still weak enough to need a follow up melee on T6+ resilience. Instant breakout with max heat meter provides small immunity window to avoid being refrozen, also doesn't benefit from roaring flames but can proc it.
Still fits the original idea of burning steppes but gives a better usage as either a dmg boost or emergency save in stasis heavy activities, cause let's be honest this exotic kinda fails on the MAIN THING it's created for being a stasis counter as a whole, also gives firesprites a decent usage
