Over the course of her life, Ororo Monroe has been trained as a juvenile thief, worshiped as a goddess, and hated as a mutant. Since Charles Xavier enlisted her to join the X-Men, Storm has grown as a warrior and as a leader.Marvel Source
Her control over the climate has been honed through constant training and numerous battles, and her arsenal of elemental powers, from shattering lightning strikes to freezing winds, make her a force of nature to be feared and respected.
The Doctor Doom Medallion helps with alot of your skills, thundering tempest, lightning storm, etc. And it gives you a nice Survivability bonus with the fear effect.
The costume core is kinda self explanatory.
And in the artifacts i targeted spirit regen and survivability the regen so you can continue casting your boom boom bam spells without having to wait for spirit, same reason why i put so many points into Spirited, and the invuln is just well storm is kinda squishy and that can help her just plow through spamming those spells.
Thank you for checking out my build for storm!
