While in the player's inventory, the Demon Will Aura Gauge will display a HUD element to show how much Demon Will is in the local Aura.
From top to bottom, the measured Will aspects are:
• Raw
• Corrosive
• Steadfast
• Destructive
• Vengeful
See overleaf for an image of the Gauge's HUD Element.
Aura Gauge HUD Element
This gauge will appear in the top left of your screen. The coloured bars will give you a good estimate of how much of each Will Aspect is in the current chunk.
You can hold [Shift] to get a numerical value for each Aspect, between 1 and 100 Will for each. 100 is the maximum amount of any one aspect of Will that a chunk can have in it.
