Archdemon

 Description The Archdemon is the sixth of 12 Legendary Minions, residing in Group 2.

It spawns by merging two level 5 Portals. When spawned, you will receive a level 1 Portal via Skully.

The Archdemon produces 15 Darkness and gives a 10% chance to level skip. You may only benefit from the chance to level skip from three Archdemons, topping out at 30%.

It gives 20% Time Shard bonus, with a 10% bonus for each subsequent Archdemon. Having the Reaper, Cyclops, and Archdemon provides a 40% Time Shard bonus.

It can be merged with the Harpy to create The Infernal.

It can be fed to The Devourer with 10 or more Legendary Minions inside the Lair.

 Trivia
 * The total cost to summon a Archdemon is 960 Blood Runes and 960 Death Runes.
 * The level skip gives the summoning percentage for champions of the minion skipped to (although this bonus is usually inconsequential).
