When using the 'Apply Rend to armour' option from a combat roll, the reduction in armour value is not tracked anywhere on the token's stats.
The current armour value will appear to be at its original value. However, subsequent damage will be applied correctly with the armour value reduced. From: MadDave123#3059 age-of-sigmar-soulbound: 4.0.0 soulbound-core: 1.0.0
Add Status Effect "Rended" or other cool word. It will be automatically activated when rend was successfully applied to armour.
Add popup bobble when cursor hover over token with information. I have something like that from module https://github.com/illandril/FoundryVTT-token-tooltips and is really useful because you can custom what you want to see.
I would say that a status effect should be related to the actor itself, not an item on an actor
If a module does a good job at something, I see no reasons to try and take users away from using it by putting it in the system. Also I'm not really sure how a tooltip is relevant here. If I understand the issue, is that armor value is a single property, there's no "base" armor data (like Rended heavy armour might be 1/3 armour value)
The solution would simply to be add another property that denotes damage to the armor, so the user knows their heavy armor is 1/3 instead of just 1.
