Description:
When wearing the Nobility in Decay set, it is impossible to have Living Corpse (from Bone Armor) and Beautiful Corpse (from the Nobility in Decay set bonus) active simultaneously.

Because Living Corpse is not displayed as a visible buff or status effect, it is difficult to track directly. However, the following test reliably reproduces the issue.

Steps to reproduce:

1. On a skill bar without Nobility in Decay, cast Bone Armor (or the Summoner’s Armor morph).
Living Corpse is applied and you are able to use the corpse consumer Necrotic Potency (the morph that restores 6 Ultimate).
2. Switch to a skill bar with Nobility in Decay equipped and cast Bone Totem.
The Beautiful Corpse buff appears in the Active Effects list.
3. Cast Necrotic Potency.
You receive only 6 Ultimate instead of the expected 12 Ultimate.
Expected result: If Living Corpse and Beautiful Corpse are both active, Necrotic Potency should consume two corpses and grant 12 Ultimate.
Actual result: Only Beautiful Corpse is consumed, and Living Corpse appears to be overridden or ignored, resulting in only 6 Ultimate.
Conclusion: It appears that Beautiful Corpse replaces Living Corpse, meaning both effects cannot coexist on the character at the same time.

Additional issue:
When Bone Armor is used on a bar with Nobility in Decay equipped, both Living Corpse (from Bone Armor) and Beautiful Corpse (from the set bonus) trigger their internal cooldowns, but only one corpse (Beautiful Corpse) is actually granted.

Design clarification / suggestion:
If it is intended behavior that Living Corpse and Beautiful Corpse cannot be active simultaneously, there should be a clear priority system. For example:
1. First GCD – casting Bone Armor on a Nobility in Decay bar grants Beautiful Corpse (set bonus).
2. Second GCD – a corpse consumer is used to consume Beautiful Corpse.
3. Third GCD – casting Bone Armor again grants Living Corpse, since the Nobility in Decay effect is on cooldown.
