Sun God's Divine Lineage

You have unlocked a hidden part of your soul which encompassed your legacy

[The Fire] You are immune fire damage. You can use the heavenly flames of Sun God to imbue yourself to get +3 to your AC for 1 minute, imbue any weapon you posses for an additional 2d10 damage and ignore any flame resistance or immunity for 1 minute or use it to dispel all negative effects and heal a person you touch to max hp. You can only use each ability of Sun God once per long rest.

[Ruin] Once your Soul Core is fully saturated, you can detonate it to deal 15d20 fire damage which ignores any resistances or immunities. After you use this ability your character will die.
