Archdemon

 Description The Archdemon is the sixth of 12 Legendary creatures, 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 cannot be fed to The Devourer.

 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).
