Exarch's Elekk.
Summon Exarch's Elekk summons an elekk for the Paladin to mount and pursue justice at blinding speeds.
Can be trained at level 20 from any Paladin class trainer. The Paladin also automatically gains the Apprentice Riding skill (75) when learning Summon Exarch's Elekk, allowing them to ride the mount immediately.
This can only be learned by draenei.
