Tutorial/Immortal Construct

A nigh-immortal life form created through bio-alchemy. The Immortal Construct burns its life to enter the "Lifeflare" state, in which it gains several HP shields at one time. Any DMG dealt by it while in this state will restore its HP.
When the number of HP-restoring shields goes below a certain number or after Lifeflare lasts for a set time, the Immortal Construct will attempt to unleash "Scorching Radiance." To stop it, you must break all of its HP shields.
The Immortal Construct will be unable to recover any HP when affected by Stellar Glimmer reactions, no matter what it does...
