Rocket Shredder 9001

The salesgoblin always tells people about the RS-9001's huge variety of attachments, but somehow neglects to mention that you never get to pick the attachments it'll have when you mount up.

Riding Requirements:

This mount is available to all eligible characters on your account.
Level 10
Apprentice Riding (ground)
Expert Riding (flying)

Source:

Recruit-A-Friend reward.

Notes:

This mech-suit is a reward from the updated Recruit-a-Friend program, added in Patch 10.0.7. You will receive this reward after your recruits subscribe for a combined total of 6 months. Note that if you recruit one player who subscribes for 6 months you'll only receive this mount once the final month has been reached, but if you recruit six players who subscribe for 1 month each you should receive your mount immediately (this is how it worked prior to 10.0.7 and is likely to remain the case). See Blizzard's official announcement for more details.

Introduced in:

Patch 10.0.7

Travel Mode:

Ground (+60% or +100% speed)
Flying (+150%, +280% or +310% speed)

Speed depends on your riding skill.
