EDITED-

I've updated the idea for the solar aspect, partial credit goes to the guy in the comment section for this but I wanted to change it a little bit so it didn't have so much in one aspect.

Tempered Plating- Hold [Barricade] to coat yourself in pure solar energy that emits a burst of flame every few seconds that damages enemies and applies Scorch. While this effect is active ignition final blows extend the duration and grant Cure.

Base duration is 10 seconds. Ignition final blows will extend it by 5 seconds because I know with some builds ignitons are a bit more rare.

The timer Cannot exceed 10 seconds however.

Only extend it back up to 10 seconds like Devour.

Release a pulse every 2 seconds. This includes the initial activation so in total its 6 bursts.

Base Scorch applied 15 stacks

With the fragment that applies more Scorch- 20 stacks
