There are two kinds of Paragons:
Paragons can be identified by their name extension (grand/elite) as well as their color coded overhead Paragon tag as shown in the picture.
Grand Paragons are a stronger variants of it's original.
Elite Paragons are even stronger than Grand Paragons.
Paragons are more aggressive than regular monsters — they will immediately lock onto and pursue any enemy that enters within 10 tiles, provided they have line of sight (AcquireOnApproach). Regular monsters only detect targets periodically during their AI cycle, but Paragons react instantly the moment you step into their view. They also cannot flee from combat, and their poison is one level stronger than their base type.
On every creature spawn, there is chance that a mob gets transformed into a Paragon.
The chance depends on the region the mob spawns in.
The loot is up scaled accordingly to the new stats and skills of the creature.
Additionally, each paragon will have a Paragon Chest in its loot.
The higher the players luck value and the tougher the enemies they defeat, the higher the level (1-6) of the Paragon Chest they'll receive. Color coded as shown in the picture.
To open a Paragon Chest, you need to pick the lock and deal with the trap.
