[2022] The next step in itemization and player agency

It does work. The burning ground from searing exarch altars is identical to other sources of burning ground.

After discussion with some designers, I think I've worked out why so many people think it's bypassing immunity, and it's because there's a different effect not caused by the altar mod - entirely separate to the altar, apparently some exarch monsters use the oil ground effect introduced in heist, where they spread an oil ground effect, that can later be set on fire to add burning damage to the existing oil ground effect. That's not burning ground because it's spawned as a separate ground effect with a different effect that doesn't burn, and later has a second stat added. We're looking into whether this can be changed so the burning part is done using the regular burning ground debuff so that part of the effect would be treated as burning ground.
