Less Rabi is arguably the most difficult achievement
pre-raiding.  It requires perfect group composition and
extreme precision and organization.  The achievement requires
you to venture into Gundrak, located in north eastern
Zul’Drak.  Once there, the third boss in the
instance is your man.  His name is Moorabi, High Prophet of
Mam’Toth.  The achievement reads: “Defeat
Moorabi in Gundrak on Heroic Difficulty while preventing him from
transforming into a mammoth at any point during the
encounter.”  This guide will offer a list of
abilities that are effective interrupts on Moorabi and a few different
strategies on how to execute your interrupts to perfection.



style="font-weight: bold; font-style: italic;">The
science behind the transformation cast-


The base cast time of Transformation is 4 seconds.  Moorabi
has an ability called Mojo Frenzy which connects his spell haste
directly to his health percentage.  Example:  If
Moorabi has 100% health, his haste rating is 0% which makes
transformation a 4 second cast.  At 75% health his haste
rating is 25%, making Transformation a 3 second cast.  At 50%
its 2 seconds, 25% its 1 second, and
at 1% health Transformation is a
.04 second cast (which in reality with lag is basically impossible to
interrupt).  That is the difficult part of the
fight.  When Moorabi’s health is above 50% his time
between casts is 10 seconds, below 50% it’s 5
seconds.  I know most of you are thinking, “Well,
what if he is between casts when he hits 50%?” The answer is
that he will continue his 10 second interval until his next cast then
begin his 5 second interval.



style="font-weight: bold; font-style: italic;">Interruption
abilities-


Moorabi is immune to silences, stuns, and cast slowing
abilities.  Here is a list of abilities that are top interrupt
choices.

 

style="font-weight: bold; font-style: italic;"> style="width: 35px; height: 32px;" alt="Hammer of Justice"
src="http://www.tentonhammer.com/image/view/70051">Hammer
of Justice (60 second cooldown, 40 second with 2/2 Improved Hammer of
Justice)- A melee range
interrupt that locks out spells for 3 seconds.



style="font-weight: bold; font-style: italic;"> style="width: 36px; height: 33px;" alt="Spell Lock"
src="http://www.tentonhammer.com/image/view/70058">Spell
Lock (Felhunter) (24 second cooldown)-
Very difficult to time properly but is still a decent interrupt that
lasts 6 seconds.



style="font-weight: bold; font-style: italic;"> style="width: 36px; height: 33px;" alt="Counterspell"
src="http://www.tentonhammer.com/image/view/70048">Counterspell
(24 second cooldown)- Is an
8 second interrupt.  This is by far the best interrupt ability
any class has.



style="font-weight: bold; font-style: italic;"> style="width: 35px; height: 33px;" alt="Kick"
src="http://www.tentonhammer.com/image/view/70052">Kick
(10 second cooldown)- Is a
simple interrupt that lasts 5 seconds.  Improved kick
won’t help here because he is immune to silence.



style="font-weight: bold; font-style: italic;"> style="width: 35px; height: 33px;" alt="Fan of Knives"
src="http://www.tentonhammer.com/image/view/70050">Fan
of Knives (no cooldown)-
Requires 2/2 points in Throwing Specialization to get a 100% chance to
interrupt.  Bad thing here is that it takes 50
energy.  Good thing is that you can pop adrenaline rush and
spam it under 10% health.



style="font-weight: bold; font-style: italic;"> style="width: 35px; height: 33px;" alt="Shield Bash"
src="http://www.tentonhammer.com/image/view/70057">Shield
Bash (12 second cooldown)- If
your tank is a warrior this is a great interrupt.  It
interrupts the target for 6 seconds, which gives an extra 1 second to
DPS when Moorabi is below 50% health.



style="font-weight: bold; font-style: italic;"> style="width: 34px; height: 32px;" alt="Pummel"
src="http://www.tentonhammer.com/image/view/70055"> style="width: 34px; height: 32px;" alt="Monkey Pummel"
src="http://www.tentonhammer.com/image/view/70056">Pummel-
There are 2 different Pummels.  One is an ability that Fury
Warriors have that interrupts the target for 4 seconds with a 10 second
cooldown.  The other is an ability that gorillas have that
locks out for 2 seconds with a 30 second cooldown.  If your
hunter can properly time his pet’s Pummel this could be a
viable option (works just like Spell Lock).



style="font-weight: bold; font-style: italic;"> style="width: 35px; height: 33px;" alt="Earth Shock"
src="http://www.tentonhammer.com/image/view/70049">Earth/Wind
Shock (6 second cooldown, 5 seconds with 5/5 Reverberation)-
Are ranged instant cast interrupts.  With 5/5 Reverberation
this could be the only interrupt your group needs (I will explain
further on this later in the guide).



style="font-style: italic; font-weight: bold;"> style="width: 33px; height: 32px;" alt="Mind Freeze"
src="http://www.tentonhammer.com/image/view/70054">Mind
Freeze (10 second cooldown)- Just
like Pummel and Kick.  Just a simple Interrupt with a lock out
that lasts less than 5 seconds.



style="font-weight: bold; font-style: italic;"> style="width: 35px; height: 33px;" alt="Maim"
src="http://www.tentonhammer.com/image/view/70053">Maim
(10 second cooldown)- Is an
ability that Cat form Feral Druid possess.  Maim is a stun
with a 3 second spell interrupt added on, even though the stun is
completely pointless the interrupt is still instant cast.



[protip]Priests are the only class without a spell interrupt[/protip]






style="font-weight: bold; font-style: italic;">Strategies-

There are countless different strategies and group comps that can
accomplish this achievement, but, there are few that make it
easy.  In this strategy portion of the guide I am going to
give a brief explanation of what would make an effective interrupt
group.  Before I begin, keep in mind this is an extremely easy
fight if you aren’t going for the achievement.  A
healer and/or tank are NOT necessary to do this achievement. 
Also, when your group uses interrupts that last longer than 5 seconds
when Moorabi is under 50% health it is strongly suggested to use some
sort of debuff countdown because you know Moorabi is going to attempt
his next cast the very moment that interrupt falls off.  This
will throw off your timing if you are using a stopwatch because instead
of 5 seconds between casts it could be 6 or 8.



style="font-style: italic; font-weight: bold;">Strategy
1- Use a basic group with a
healer, tank, and 3 DPS.  The only catch is that one of your
DPS is an Elemental Shaman with 5/5 talent points in
Reverberation.  The key here is that your Shaman must have his
in-game stopwatch started the moment Moorabi begins to cast the first
transformation, that way he/she should always be ready to interrupt at
every 10 second interval until 50%, then every 5 second
interval.  The big thing is that the Shaman’s
cooldown is identical to Moorabi’s time between
casts.  Therefore the Shaman should be spamming his/her Earth
Shock the entire fight.  It is extremely important the shaman
is the only one interrupting during this strategy.



style="font-weight: bold; font-style: italic;">Strategy
2- This strategy requires a
nontraditional group comp.  4 DPS and a tank will do the trick
here.  Specifically a Shadow Priest, Mage, and 2 additional
DPS and a tank.  The key to this strategy is that the Mage
uses Counterspell at the cast closest to 30%.  This gives the
group 8 seconds to dig in and do as much damage as possible. 



It is possible to complete this achievement with as little as 2
interrupts (other than Earth Shock with 5/5 Reverberation), but I just
don’t recommend them because they rely so much on
luck.  If you do try another tactic I strongly advise you to
not use a healer for the simple reason that the more DPS you have, the
less casts Moorabi will attempt below 35%.  Those 2 strategies
are the most fool proof ways to acquire Less Rabi.  Just be
smart, keep your head on a swivel and you might just achieve the
impossible.
